Neural encoding in orbitofrontal cortex and basolateral amygdala during olfactory discrimination learning. (1/2509)

Orbitofrontal cortex (OFC) is part of a network of structures involved in adaptive behavior and decision making. Interconnections between OFC and basolateral amygdala (ABL) may be critical for encoding the motivational significance of stimuli used to guide behavior. Indeed, much research indicates that neurons in OFC and ABL fire selectively to cues based on their associative significance. In the current study recordings were made in each region within a behavioral paradigm that allowed comparison of the development of associative encoding over the course of learning. In each recording session, rats were presented with novel odors that were informative about the outcome of making a response and had to learn to withhold a response after sampling an odor that signaled a negative outcome. In some cases, reversal training was performed in the same session as the initial learning. Ninety-six of the 328 neurons recorded in OFC and 60 of the 229 neurons recorded in ABL exhibited selective activity during evaluation of the odor cues after learning had occurred. A substantial proportion of those neurons in ABL developed selective activity very early in training, and many reversed selectivity rapidly after reversal. In contrast, those neurons in OFC rarely exhibited selective activity during odor evaluation before the rats reached the criterion for learning, and far fewer reversed selectivity after reversal. The findings support a model in which ABL encodes the motivational significance of cues and OFC uses this information in the selection and execution of an appropriate behavioral strategy.  (+info)

Quantitative structure-activity relationships for nasal pungency thresholds of volatile organic compounds. (2/2509)

A model was developed for describing the triggering of nasal pungency in humans, based on the partition of volatile organic compounds (VOCs) between the air phase and the biophase. Two partition parameters are used in the model: the water-air partition coefficient and the octanol-water partition coefficient. The model was validated using data from the literature, principally on alcohols, acetates and ketones. The model suggests that all test compounds, regardless of their chemical functional groups, bind to a common receptor site within the hydrophobic interior of the bilayer membrane of the trigeminal nerve endings. There is probably only a slight, non-specific interaction between the VOC molecule and the receptor molecule, whereas this type of non-specific interaction for the detection of odor is much stronger. In practical terms, the suggestion that all VOCs share a common irritation receptor site implies that nasal-pungency thresholds of individual VOCs may be additive. Quantitative structure-activity relationships (QSARs) for nasal-pungency thresholds were also developed from the model, which can be used to predict nasal-pungency thresholds of common VOCs. Although the present model does not offer additional precision over that of M.H. Abraham et al., 1996, Fundam. Appl. Toxicol. 31, 71-76, it requires fewer descriptors and offers a physiological basis to the QSAR. Another advantage of the present model is that it also provides a basis for comparison between the olfactory process and nasal pungency.  (+info)

A technique for assessing the effects of olfaction on feed preference in lactating Holstein cows. (3/2509)

Our objective was to develop a method for assessing the effects of olfaction on feed preference. Two multiparous lactating Holstein cows were offered a totally mixed ration consisting of corn silage, alfalfa haylage, and a ground corn and soybean meal-based concentrate mixture (25:25:50 on a DM basis) for their ad libitum consumption in four consecutive 2.5-h periods daily for 5 d. An apparatus was developed that allowed odorants to be distributed at a set rate over two feeding containers with limited possibility of odor carryover. Four odorants and a control (no odorant) were compared against each other. All possible comparisons were conducted on the left and right feeding sides to avoid potential lateral-preference effects. Rank values of 0 or .5 were assigned to each odorant based on the percentage of total feed consumed in a period. A test of overall equality based on the sums of squares of ranks was used to determine whether odors affected preference. The limited results indicated that inhalation of odorants did not affect preference. Rank values were doubled for several odorants when compared with others, which suggested that the sample size limited experimental sensitivity. To attain reasonable power, we estimated that at least six cows were needed per study. Large effects of odorants on feed preference would have been required to reach statistical significance in this trial; however, the method provides a practical technique for testing the effects of olfaction on feed preference in cattle when the suggested number of cows is used.  (+info)

Blind smell: brain activation induced by an undetected air-borne chemical. (4/2509)

EEG and behavioural evidence suggests that air-borne chemicals can affect the nervous system without being consciously detected. EEG and behaviour, however, do not specify which brain structures are involved in chemical sensing that occurs below a threshold of conscious detection. Here we used functional MRI to localize brain activation induced by high and low concentrations of the air-borne compound oestra-1,3,5(10),16-tetraen-3yl acetate. Following presentations of both concentrations, eight of eight subjects reported verbally that they could not detect any odour (P = 0.004). Forced choice detection performed during the presentations revealed above-chance detection of the high concentration, but no better than chance detection of the low concentration compound. Both concentrations induced significant brain activation, primarily in the anterior medial thalamus and inferior frontal gyrus. Activation in the inferior frontal gyrus during the high concentration condition was significantly greater in the right than in the left hemisphere (P = 0.03). A trend towards greater thalamic activation was observed for the high concentration than the low concentration compound (P = 0.08). These findings localize human brain activation that was induced by an undetectable air-borne chemical (the low concentration compound).  (+info)

The effect of age on odor-stimulated functional MR imaging. (5/2509)

BACKGROUND AND PURPOSE: The effects of age, sex, and handedness on olfaction have not been adequately addressed with odor-stimulated functional MR imaging studies. We sought to determine the effect of age on functional MR imaging experiments performed with odor stimulation. METHODS: Five right-handed subjects with a mean age of 73 years and five right-handed subjects with a mean age of 24 years underwent gradient-echo echo-planar functional MR imaging using binasal olfactory stimulation. Imaging parameters included 3000/30 (TR/TE) and a 5-mm section thickness in a 6-minute sequence with 30 seconds of pulsed odorants alternating with 30 seconds of room air. The data were normalized to a standard atlas, and individual and group statistical parametric maps (SPMs) were generated for each task. The SPMs were thresholded for a P < .01, and the volumes of activation and distribution of cluster maxima were compared for the two groups. RESULTS: Analysis of the group SPMs revealed activated voxels in the frontal lobes, perisylvian regions, and cingulate gyri, with greater volume in the younger group than in the older group. The right inferior frontal, right perisylvian, and right and left cingulum had the largest number of voxels activated. The most common sites of activation on individual maps in both groups were the right inferior frontal regions and the right and left superior frontal and perisylvian zones. CONCLUSION: Given similar olfactory task paradigms, younger subjects showed a greater number of activated voxels than did older subjects. One must be cognizant of this effect when designing studies of odor-stimulated functional MR imaging.  (+info)

The effect of odour priming on long latency visual evoked potentials of matching and mismatching objects. (6/2509)

This study reports a cross-modal, olfactory/visual event related potential (ERP) using odours as olfactory primes. The results show a difference in the ERP waveform for the N400 waveform when a visual image does not match the priming odour. An N400 peak was produced for both the matched and mismatched conditions but the peaks were significantly more negative for the mismatched condition. By the use of non-food odours this study extends an earlier finding by Grigor, who, using the same ERP paradigm, obtained similar results for food odours and photographs of food.  (+info)

Visual event related potentials modulated by contextually relevant and irrelevant olfactory primes. (7/2509)

Visual evoked potentials were recorded from 16 scalp locations on 10 young subjects during presentation of a series of high-quality photographs on a computer screen. The photographs consisted of equal numbers of pictures of fruit (citrus and non-citrus fruits), flowers (roses and other flowers) and objects (e.g. buildings, vehicles, animals etc.). Every picture was different in order to avoid repetition effects. The pictures were presented under four odour conditions: no odour, rose odour, jasmine odour and citrus odour. In order to keep the subjects alert they were asked to make categorizing decisions for the visual stimuli (e.g. flower or fruit). No decision was required concerning the relationship between the visual stimulus and the odour. As expected, the N400 peak was more negative when the picture stimulus did not match the odour. It is hypothesized that the N400 peak can be used as a measure of relatedness of a sensory stimulus to a previous or on-going prime, irrespective of the mode of the stimuli.  (+info)

Sensory perception is related to the rate of change of volatile concentration in-nose during eating of model gels. (8/2509)

The relationship between perceived aroma and the volatile concentration measured in-nose was investigated during eating of a model food. Sensory ranking and time-intensity analysis (TI) were used to measure perceived aroma, while in-nose volatile concentration was monitored by atmospheric pressure ionization mass spectrometry, which produced time release data. A gelatine-sucrose gel with a range of gelatine concentrations (2-8% w/w) and flavoured with furfuryl acetate was used as the model food. Sensory scaling showed decreased flavour intensities and TI showed a decrease in the flavour perceived over time, as the gelatine concentration increased. Studies in model systems and in people demonstrated that the different rates of release observed for different gelatine concentrations were not due to binding of volatile to protein in the gel, nor to mucous membranes, but were due to different rates of gel breakdown in-mouth. There were no significant differences in the maximum in-nose volatile concentrations for the different gelatine concentrations, so the amount of volatile present did not correlate well with the sensory analysis. However, the rates of volatile release were different for the different gels and showed a good correlation with sensory data.  (+info)

In the following we describe the methodological details of appetitive associative olfactory learning in Drosophila larvae. The setup, in combination with genetic interference, provides a handle to analyze the neuronal and molecular fundamentals of specifically associative learning in a simple larval brain.,br /,Organisms can use past experience to adjust present behavior. Such acquisition of behavioral potential can be defined as learning, and the physical bases of these potentials as memory traces. Neuroscientists try to understand how these processes are organized in terms of molecular and neuronal changes in the brain by using a variety of methods in model organisms ranging from insects to vertebrates. For such endeavors it is helpful to use model systems that are simple and experimentally accessible. The Drosophila larva has turned out to satisfy these demands based on the availability of robust behavioral assays, the existence of a variety of transgenic techniques and the elementary ...

Take-home message: -30 to 80% of people with COVID-19 report loss of smell, known as anosmia. -The likely targets of the SARS-CoV-2 virus are supporting cells in the nose that support growth of the nerve cells that allow us to smell -Anosmia treatments being studied include: Retraining the brain to smell, calming nasal inflammation and finding ways to regrow damaged nasal cells One year, my dad came down with a terrible cold and a very high fever. As with many colds hed had before, he lost his sense of smell. But this time, it didnt come back. By Christmas that year, we were all gathered in the kitchen as my dad cooked a big family dinner. My cousin, who was standing near the stove, said she smelled gas. It turned out one of the burners was no longer lit and gas was escaping quickly through the house. My dad, who had been at the stove the entire time, couldnt smell it at all. So while losing your sense of smell seems like a mere inconvenience, if you cant smell a gas leak or smoke from a fire, or
PNAS, 22 February, 2019, DOI: https://doi.org/10.1073/pnas.1812342116. Suppression of GABAergic neurons through D2-like receptor secures efficient conditioning in Drosophila aversive olfactory learning. Mingmin Zhou, Nannan Chen, Jingsong Tian, Jianzhi Zeng, Yunpeng Zhang, Xiaofan Zhang, Jing Guo, Jinghan Sun, Yulong Li, Aike Guo, and Yan Li. Abstract. The GABAergic system serves as a vital negative modulator in cognitive functions, such as learning and memory, while the mechanisms governing this inhibitory system remain to be elucidated. In Drosophila, the GABAergic anterior paired lateral (APL) neurons mediate a negative feedback essential for odor discrimination; however, their activity is suppressed by learning via unknown mechanisms. In aversive olfactory learning, a group of dopaminergic (DA) neurons is activated on electric shock (ES) and modulates the Kenyon cells (KCs) in the mushroom body, the center of olfactory learning. Here we find that the same group of DA neurons also form ...
It wasnt until several years had passed after I moved out of my parents home that I could finally smell their house smell. All the years that I lived there I never knew the smell of my own house. This of course does not take into account the obvious years that we had a cat. This past summer I think I figured out the mystery of being able to smell your own house. We were away for about a month with no one staying at our house during this time. When we arrived back home there was no food or people smell to interfere with the true house smell. For once I was able to experience my house odor as if I was a stranger visiting for the first time. Overall I would say my house smelled pleasant but a bit stale, presumably from having the windows shut for so long. I was happy to know that my house didnt have any funk smell to it like some houses I have been in before ...
I opened a couple racks of ribs a couple weeks back that had a strong sulfur smell. Even after all that I could justify cooking them, rotten is rotten. If the steaks feel sticky to the touch or slimy, they need to be discarded. Bought a large bone in pork butt yesterday to cook today. Pork shoulder smells like rotten eggs. However, like thirdeye pointed out, if the smell was strong then maybe you have an alternate issue. If it doesnt then it is bad. The smell should dissipate and after a quick rinse, the pork itself shouldnt really smell much at all. That portion has a large bone and was bloodier than the rest of the piece. As I was removing the pork skin, I smelled the area where the leg was cut off from it and noticed a very slight scent of manure or something like it. I threw them out and after looking back was glad I did. It is a different smell from spoilage. Wash it off, let it sit for a few minutes, if the smell dissapates, it is cryovac funk.

But what about smells? Digital images are essentially throwaway items, so could an aroma better capture a mood or event?. London, UK-based designer Amy Radcliffe thinks so. Thats why she created the Madeline, a device that holds onto smells.. The idea: Sniffing stored odors at a later date will bring important memories flooding back in a way Facebook photos just cant match.. The Madeline is a strange-looking device, but its by no means new. In fact, scientists in the fragrance industry have been using technology like it for years.. In order to capture a smell, an object is placed inside a glass dome connected by an air hose to an odor trap. Recording a smell isnt an instantaneous process; it can take hours or even days to properly capture the aroma of a chosen item.. (That makes me wonder if youre capturing the moment associated with the smell or just the memory of the smell storage process.). Its a very delicate process, but thats the intention.. Your odor memories are very fragile; if ...
Olfactory sensory neurons project axons to the brain within the olfactory nerve, (cranial nerve I). These nerve fibers, lacking myelin sheaths, pass to the olfactory bulb of the brain through perforations in the cribriform plate, which in turn projects olfactory information to the olfactory cortex and other areas.[17] The axons from the olfactory receptors converge in the outer layer of the olfactory bulb within small (≈50 micrometers in diameter) structures called glomeruli. Mitral cells, located in the inner layer of the olfactory bulb, form synapses with the axons of the sensory neurons within glomeruli and send the information about the odor to other parts of the olfactory system, where multiple signals may be processed to form a synthesized olfactory perception. A large degree of convergence occurs, with 25,000 axons synapsing on 25 or so mitral cells, and with each of these mitral cells projecting to multiple glomeruli. Mitral cells also project to periglomerular cells and granular cells ...

Scientists have found that the sense of smell is most accurate between the ages of 30 and 60 years. It begins to decline after age 60, and a large proportion of elderly persons lose their smelling ability. Women of all ages are generally more accurate than men in identifying odors.. Some people are born with a poor sense of smell or taste. Upper respiratory infections are blamed for some losses, and injury to the head can also cause smell or taste problems.. Loss of smell and taste may result from polyps in the nasal or sinus cavities, hormonal disturbances, or dental problems. They can also be caused by prolonged exposure to certain chemicals such as insecticides, and by some medicines.. Tobacco smoking is the most concentrated form of pollution that most people are exposed to. It impairs the ability to identify odors and diminishes the sense of taste. Quitting smoking improves the smell function.. Radiation therapy patients with cancers of the head and neck often complain of lost smell and ...

Even before COVID-19, there was a body of evidence that correlated a loss of smell with an onset of clinical depression. In fact, experiencing a loss of smell can greatly impact your sense of taste. You can get super hungry! If the sense of smell returns at times, this is not a permanent loss. While we tend not to think of smell and taste as important as our other senses, clearly its loss can interfere with the enjoyment of life-and our safety. But the smell and taste loss associated with COVID-19 appears to be unique to the novel coronavirus according to Nicholas Rowan, M.D., an assistant professor of otolaryngology-head and neck surgery at the Johns Hopkins University School of Medicine.

The first thing to do when youve noticed the smell of sewage in your faucet water is to inspect the cause and run a test to check the water chemistry. Since magnesium sulfide gas can live in the drain and pipelines, smell the water away from the drains to make sure your assessment is correct. Upon checking, youll find out the real culprit behind the smell of sewage. The simple process of stepping away from the sink will help determine the source of the problem. The isolation technique is done to identify whether the sewage smells come from the drain or from the water itself. Most likely, if its not in the drain and pipelines, its definitely in the water source. The best thing to do is to test the water for its chemistry. Whether youre using municipal water supplies or a private well, theres a high probability your water source is responsible for the unpleasant smell. Sewage smell is a clear indicator of contaminants in your drinking water. Locating the source of a smelly water problem will ...
Jay, 25, a musician in Seattle, Washington. Thinks it smells like: Sweat, urine, and human nature.. My first memory of the smell of pussy is the first time my high school girlfriend was grinding against my thigh with nothing but panties on. We made out and fooled around, but kept all the touching above underwear. The thing was, her panties were super thin, and she got super wet.. I didnt notice until I got home that night that there was a white crust on the thigh of my jeans. When I smelled it, it smelled amazing. I dont even know what drove me to smell it, but once I had, I couldnt stop. Its tough to describe it, because it smells so uniquely like what it is. Its a little like fresh sweat after a womans done exercising, but theres always more to it. I hid those jeans by the side of my bed and would smell them and masturbate every night for like a week straight!. Years later, I finally told a woman how much I loved her smell. I wish I had the self confidence I have now when I was a bit ...
That is the main difference between regular detergent and detergent made for he machines. Best to leave the skin on. This is the best way, if the vinegar smell does not bother you. Vinegar to Kill & Prevent Ticks. There are ways to do this. In addition to passing urine that smells like vinegar, affected women may experience painful intercourse and urination, genital itching, vaginal swelling, and discharge from vagina. If Buster has just taken care of business on your favorite rug, saturate the spot with undiluted vinegar to deodorize the spot. The Mead Lovers Digest mailing list (was) a good place to discuss mead brewing issues with others. The more your feet sweat, the more they may smell like vinegar. What Is Meth?

When you suffer brain trauma or head trauma these can affect your sense of smell and change how you register this sense. This condition is called anosmia. The result is the loss of olfactory functions making odors imperceptible. Both minor and major brain damage can be enough to cause this sort of damage. Without a sense of smell noticing gas leaks or toxic chemicals can pose a safety risk. Another effect can be loss of appetite from not being able to smell food.. There are functions of the brain that can be impaired that are controlled by areas close to these regions. This means that if smell and taste are damaged there could be other areas affected. The results can be emotional problems such as depression, aggressive behavioral problems, apathy, and general feelings of unconcern. It is important to address these issues after suffering from a TBI.. Recovery. It is possible to recover a sense of smell after a TBI. Some 30% of affected people have been shown to recover over time. It can happen ...
I had a horrendous smell in my nose as well. For Pitz, coffee, chocolate and red wine smell and taste awful. A more common reason for a musty smell in the nose is a sinus infection. 17th Annual Photo Contest Finalists Announced. Then the next wave of neurons needs to be generated to continue that process., Rawson says that because the brain is receiving incomplete smell information, when the recovery process is happening in patches, or recovery is partial in different regions, you may go through that stage of parosmia on the way to a fuller recovery.. We also know that nerves do not function very well within an inflammatory environment. Ammonia in an aqueous environment exists in equilibrium between ionized ammonium cation and the non-ionized ammonia. From smell training to nutritional supplements, Miguels personal journey on recovering his nose after Covid-19. Having an ammonia odor on your breath is very common in patients with more advanced (usually Stage 4 or 5) chronic kidney ...
Since the beginning of the pandemic, a loss of smell has emerged as one of the telltale signs of COVID-19. Though most people regain their sense of smell within a matter of weeks, others can find that familiar odors become distorted. Coffee smells like gasoline; roses smell like cigarettes; fresh bread smells like rancid meat.
Sense smell taste - I havent been able to smell or taste for 2 weeks. I thought it was a cold but usually I only lose my sense of smell/taste for a few days. Why? Acute neuropathy. I have seen this before. In the absence of head injury, it is somewhat of a mystery. I had one patient lose her smell and taste after a flu vaccine. I think it is due to a neuropathy or acute nerve disease of the olfactory nerve, the nerve that delivers smell, which would also affect taste. I always give a trial of steroids.
Cat urine is just like other pets urine as it can gives a very bad smell nearly impossible to mask off. It can happens quite often that your cat urinates outside the litter box and on a carpet, bed linens, clothes or furniture. It is very important to remove the urine smell to prevent your cat from repeating the same mistake again on the same spot. As you know, pets tend to return to the same spot which they previously urinated if the odor is still there. Moreover, if the problem is not being taken care off, the urine left unclean will gives out a strong ammonia smell and eventually causes more bacteria growth. Many of you, cat owners are not quick enough to clean up the urine. Thus, once the urine dries up, you might not see it on the floor but the smell cannot be avoided. Luckily, there are a few items from your house that are able to neutralize the cat urine smell like vinegar, baking soda and enzymatic cleaners. Vinegar is said to be one of the easiest and most useful product when it comes ...
Some biologically important examples would include coenzyme-A, glutathione and cysteine. However, not all thiols have fowl smell. For example, furan-2-ylmethanethiol provides the aroma of roasted coffee while grapefruit mercaptan gives grapefruit its characteristic scent. You can see a complete list here.. After seeing some examples, lets come to the main point i.e. why thiols have such foul smell. Thiols are decomposition products of proteins. When amino acids, like cysteine and methionine, are decomposed, thiols are one of the last things to form. This would explain why it becomes important to smell and avoid them (you wouldnt want to eat a dead and decaying mammoth, and a blind hunter might not be able to tell if he has found a decaying mammoth if he cant smell such compounds). As a side note, this also explains why organic acids have sour taste and smell. Compounds like glucuronic acid, citric acid, oxalic acid, lactic acid, butyric acid, acetic acid, etc. are all decomposition products ...
Loss of a sense of smell may be a more reliable indicator of Covid-19 than cough or fever, research suggests. A study by University College London (UCL) of 590 people who lost their sense of smell or taste earlier in the year found 80% had coronavirus antibodies.. Of those people with antibodies, 40% had no other symptoms. The research only looked at people with mild symptoms, however. Evidence that loss of smell and taste could be signs of coronavirus began to emerge from about April, and they were added to the official list of symptoms in mid-May.. Current guidance states anyone who experiences a loss of, or change to their sense of smell or taste should self-isolate and apply for a test. But lead author of the UCL study, Prof Rachel Batterham, says cough and fever are still seen by many as the main symptoms to look out for.. She recruited people between 23 April and 14 May by sending out texts via four GP surgeries in London, enrolling those who reported losing their smell or taste in the ...
Invited talk, Most Influential Paper Award) In this retrospective we will review the paper Java Quality Assurance by Detecting Code Smells that was published ten years ago at WCRE. The work presents an approach for the automatic detection and visualization of code smells and discusses how this approach could be used in the design of a software inspection tool. The feasibility of the proposed approach was illustrated with the development of jCOSMO, a prototype code smell browser that detects and visualizes code smells in JAVA source code. It was the first tool to automatically detect code smells in source code, and we demonstrated the application of this tool in an industrial quality assessment case study. In addition to reviewing the WCRE 2002 work, we will discuss subsequent developments in this area by looking at a selection of papers that were published in its wake. In particular, we will have a look at recent related work in which we empirically investigated the relation between code ...
These chemicals are contained in the natural substances the body releases, like sweat, Vaginal fluid or Semen. Thus most smells are not associated with any Infections.. If someones personal hygiene is not taken care of, then these substances build up, and the smells get stronger. Washing daily, and giving particular care to areas where substances could build up (for example under the foreskin of an uncircumcised man or boy, or the Vaginal area of a woman or girl) will mean any mild smells are meant to be there and should not become unpleasant.. Some infections also cause the release of other substances from the body. These substances can have distinctive and sometimes unpleasant smells that go with them. It might be that an unusual Discharge carries a particular smell, or is an unusual colour, and this could be a clue to the presence of an infection. (An example of this is bacterial vaginosis.) This website contains details of several sexually-transmitted infections and non sexually-transmitted ...
Portland is arranged in neighborhoods everywhere but in the very center of the city, and so much of my commute to and from work is through neighborhoods of houses, and in the autumn, I love to smell the smoke from peoples fires coming from the chimneys, the smells of things cooking in their kitchens - of course the rain and the leaves and the trees all have particularly earthy smells in the autumn. Fog and mist have distinctive smells as well. The cold, crisp air of autumn and winter does heighten the smells, I think ...

Dogs sense of smell. The olfactory sensitivity of dogs ranks first among all animals, and blind dogs can use their noses to live like normal dogs. The sensitive sense of smell of dogs is mainly manifested in two aspects: one is the sensitivity to smell; the other is the ability to distinguish smell. Sensitivity varies depending on the type of taste, which is about 1200 times that of human smell. The dogs nose can distinguish about 2 million different odors, and it also has a high degree of analysis ability, able to smell the kind of odor it is looking for from many mixed odors. The ability of dogs to perceive smell can reach the molecular level. For example, when 1 cubic centimeter contains 9000 butyric acid molecules, dogs can smell it, and in general, there are about 268×10.e+16 molecules per cubic centimeter of air. Therefore, dogs can feel the concentration of butyric acid at 3.36×10.e-17. When someone dilutes sulfuric acid by one tenth of a million, dogs can still smell it, and the ...
Parosmia (a distorted sense of smell) is marked by the perception of certain smells as unpleasant (such as chemicals, burning, or mold) or different upon each new inhalation.. This disorder is often caused by traumatic brain injuries because they can inflict damage on the olfactory bulb, which is a structure in the brain that gives it information about perceived scents.. A bacterial or viral infection can also cause parosmia because upper respiratory infections can inflict damage on olfactory neurons.. Progressive brain disorders such as Alzheimers and Parkinsons disease are marked by the formation of beta-amyloid plaques in the olfactory and central nervous systems and can lead to a distorted sense of smell as well.. You smell things that arent ...
Illustration of the anatomy of smell. The perception of smell starts in the lining (mucosa) of the nose, where tiny hair-like receptor nerve cells detect airborne chemicals. Activated receptor cells transmit messages to the olfactory bulb, just above the nasal cavity. The olfactory bulb is a swelling on the end of the olfactory nerve which carries the sensory impulses to the brains smell centres. These olfactory centres lie brains frontal lobe and limbic system, which interpret the impulses to produce the sensation of smell. - Stock Image C027/6959
November 06, 2014. By Dorothy Rowley. Special to the NNPA from The Washington Informer. Older adults whove lost their sense of smell - namely, the ability to pick up on strong odors like smelly socks or bacon sizzling in a pan - could be at an increased risk of death within five years, according to a study involving more than 3,000 people ages 57 to 85.. The study, which published recently in the science journal PLOS ONE, revealed in a smell test conducted in 2005, that nearly 40 percent of subjects who failed died within five years, compared to a 19 percent death rate within five years for those with moderate smell loss. Ten percent of the test subjects were determined to have a healthy sense of smell.. During the test, Sniffin Sticks, which resemble felt-tip pens, were loaded with five different scents - peppermint, fish, orange, rose or leather - that subjects were asked to identify.. Nearly 78 percent of those tested who were able to identify at least four of the five scents, were ...
Every pet owner has to deal with the occasional indoor accident whether it is before a young pet is properly housetrained, consequences of an illness, the aging of a pet or just an overly excited or stressed pet that may have less control. What no pet owner has to deal with, however, is the ongoing smell from urine accidents. With the proper steps, it is easy to control odors and eliminate pet urine smell entirely.. 12 Easy Ways to Eliminate Pet Urine Smells. Depending on a pets diet, health and the frequency of accidents, urine smells can become quite overpowering. Fortunately, there are easy ways to eliminate those odors… ...
Smell is one of the five senses. It is how we interact with the world. What does the smell of a good meal mean to you? What are good smells and what are bad smells? Are there effects beyond just being pleasant or unpleasant? Specific odors that represent food or indicate danger may be capable of altering an animals lifespan and physiological profile by activating a small number of highly specialized sensory neurons, researchers at the University of Michigan, University of Houston, and Baylor College of Medicine have shown in a study publishing by the end of April in the online, open-access journal PLoS Biology.
The Secret of Scent. Author Luca Turin (here he is on TED) breaks down scent chemistry for the reader in fairly simple terms. For me, one of the upshots is that there are no smell-alikes in nature. The same compounds always cause the same aromas. Its possible for things to smell close to one another, or to create scent illusions where a set of compounds combines and sort of evokes or mimics another compound, but it can never be exactly alike - because the only thing that would smell exactly like a given smell is the molecule responsible for it. And so if you smell something, a molecule in the aroma is causing it. If you notice a similarity, some similarity is really there - even if, culturally, people perceive the two things as pleasant or unpleasant ...
We have five senses and smell just may be the most powerful of them. It is through life experience that we learn what should smell good and what smells bad. What we think about a waft from a barrel of hot, salty boiled peanuts or the blend of potatoes, lobster, and sausage will either make our mouth water or our nose shrivel up in disgust. Our sense of smell drives hunger, memory, emotions, and attraction.. When I was a teenager, my first boyfriend wore Drakkar Noir, a popular cologne in the early 1990s. Still to this today when I catch a hint of the unique scent, Im reminded of a moment from our multi-year relationship. He was my first true crush, my first love, and my best-friend. Drakkar Noir will forever bring a little smile to my face as I recall my memories of that time.. Just behind your nose in your nasal passages are sensory cells about the size of a postage stamp. Its these little receptors that pick up the molecules of odor as they waft by. Some may cause us to have an obvious ...

Some of the most common medications used by Americans cause zinc deficiency, including: the blood pressure medicines, called ACE inhibitors; loop diuretics used to treat cardiovascular problems; cholestyramine, which binds to bile acids and lowers cholesterol; oral contraceptives; stomach acid reducers, called H-2 receptor antagonists; and estrogen and hormone replacement therapies.* In the US, ACE inhibitors alone account for 130 million prescriptions annually. Diuretics are third most commonly used type of medicine in people over age 60.**. What are the risks of losing the sense of smell? MayoClinic.com says that anosmia isnt dangerous in and of itself, but an intact sense of smell is necessary to fully taste foods. So loss of smell could cause you to lose interest in eating, leading to weight loss, malnutrition or even depression. Loss of smell also prevents you from smelling things like spoiled food or smoke.. Ive already encountered that problem on my smellcation, evoking the when in ...
One thing thats obvious about cannabis is that it has a strong smell. Actually, it can have lots of different smells: skunk, berries, pine, fuel, lemon, black licorice, Girl Scout cookies…Those smells come from terpenes that are Generally Recognized As Safe, because theyre found in things we eat all the time, like pepper. The wide variety of smells means that plants can differ a lot in terpene content. Some of these terpenes are arousing. Some are relaxing. Some reduce pain and inflammation. Some may have anti-addictive properties (selective CB2 agonists). That is to say, its actually true that different strains of marijuana are better suited for different uses, or different times of day.. Common use of sativa for stimulating and indica for sedating is apparently wrong, though.. ...
its difficult to explain but the smell left me with a longing for days gone by when i was the surgical registrar on the floor. i was the guy placing the nasogastric tube when the patient brings up the nights festivities all over the bed and often my shoes, leaving a sour smell of alcohol and stomach acid. when i was the one placing a high flow line into the neck of the nth drunk uncooperative gunshot wound patient, where part of the technique is to dodge his often well placed punches. in those moments you are not aware of the smell. maybe the adrenaline drowns it out. but it is always there. the next day when you walk into casualties and the smell hits you, the nighs activities return so vividly to your mind ...
The new study utilized the University of Pennsylvania Smell Identification Test (UPSIT). This simple test is commercially available for smell identification. It has become the gold standard of smell identification tests and has now been administered to about 500,000 patients so far. Developed by Dr. Richard Doty, the test has also been used as screening test in identifying early stages of AD and has been found to be superior to other non-diagnostic clinical measures in predicting cognitive decline. The loss of odor identification is based on memory and is not the same as a loss of the sense of smell.. Several other studies have also identified altered sense of smell in cognitive decline. For example, in a very simple approach to screening for early stages of AD, University of Florida researchers asked participants to smell a spoonful of peanut butter at a short distance from their nose. The participants had a confirmed diagnosis of early stage AD, some had other forms of dementia, while others ...

The mammalian olfactory system processes odorants presented orthonasally (inhalation through the nose) and also retronasally (exhalation), enabling identification of both external as well as internal objects during food consumption. There are distinct differences between ortho- and retronasal air flow patterns, psychophysics, multimodal integration and glomerular responses. Recent work indicates that rats can also detect odors retronasally, that rats can associate retronasal odors with tastes, and that their olfactory bulbs (OBs) can respond to retronasal odorants but differently than to orthonasal odors. To further characterize retronasal OB input activity patterns, experiments here focus on determining the effects of odorant concentration on glomerular activity by monitoring calcium activity in the dorsal OB of rats using a dextran-conjugated calcium-sensitive dye in vivo. Results showed reliable concentration-response curves that differed between odorants, and recruitment of additional glomeruli, as
Although the presence of an olfactory impairment in Parkinsons disease (PD) has been recognized for 25 years, its cause remains unclear. Here we suggest a contributing factor to this impairment, namely, that PD impairs active sniffing of odorants. We tested 10 men and 10 women with clinically typical PD, and 20 age- and gender-matched healthy controls, in four olfactory tasks: (i) the University of Pennsylvania smell identification test; (ii and iii) detection threshold tests for the odorants vanillin and propionic acid; and (iv) a two-alternative forced-choice detection paradigm during which sniff parameters (airflow peak rate, mean rate, volume, and duration) were recorded with a pneomatotachograph-coupled spirometer. An additional experiment tested the effect of intentionally increasing sniff vigor on olfactory performance in 20 additional patients. PD patients were significantly impaired in olfactory identification (P , 0.0001) and detection (P , 0.007). As predicted, PD patients were also ...

However, two 2016 studies support the use of the University of Pennsylvania Smell Identification Test (UPSIT), and suggest it may offer a practical, low-cost alternative to other tests.. In one study, UPSIT was administered to 397 older adults (average age 80) without dementia, who were also given an MRI scan to measure the thickness of the entorhinal cortex (the first brain region to be affected by Alzheimers disease). After four years, 50 participants (12.6%) had developed dementia, and nearly 20% had signs of cognitive decline.. Low UPSIT scores, but not entorhinal cortical thickness, were significantly associated with dementia and Alzheimers disease, and with cognitive impairment. Entorhinal cortical thickness was significantly associated with UPSIT score in those who transitioned from MCI to dementia.. In other words, it looks like impairment in odor identification precedes thinning in the entorhinal cortex.. In another study, UPSITwas administered to 84 older adults, of whom 58 had MCI, ...

I am going to discuss a couple interesting facts that affect dog urine odor removal. First what I call Odor Memory. This is when we (humans) smell a particular odor and our brain remembers it. For example urine. If we smell urine and it gets into our nose and brain then certain things like seeing the urine stain again will trigger that smell in out brain and we will smell the urine again even if the smell is not still there. This is a psychological odor that is not a real odor but our brains cant tell the difference. Sometimes we can just think of the smell and we will smell it. It happens with all types of smells. Most of us have had this happen. This affects removing dog urine odor because we can psychologically smell the odor even after we have removed it. Sometime we wnat someone else to test smell the area we have cleaned to see if the odor is gone.. The other interesting point is that on average women can identify 10,000 distinct odors and the average man can identify 5,000 distinct ...
Frank C. Morris, Jr., Member of the Firm, and Nancy L. Gunzenhauser, Associate, will co-present Accommodating Employees with Allergies and Odor Sensitivities, a Lorman Education Services webinar.. With allergies and odor sensitivities on the rise and affecting millions of Americans, employers are increasingly confronted with the challenge of accommodating such conditions in the workplace. As a result of the ADA Amendments Act, many more employees are filing disability-related claims for failure-to-accommodate, discrimination, and retaliation, causing employers to question how to properly accommodate such conditions.. This live webinar will provide human resources professionals and attorneys with the necessary information to determine if an employee or applicant claiming an allergy or odor sensitivity is covered by the ADA, how to implement appropriate policies addressing allergies and odor sensitivities in the workplace, properly accommodate employees affected by these conditions, and ...

Methods: In 274 members of the PREVENT-AD cohort of healthy aging persons with a parental or multiple-sibling history of AD dementia, we assessed the cross-sectional association of OI with potential indicators of presymptomatic AD. Some 101 participants donated CSF, thus enabling assessment of AD pathology with the biomarkers total tau (t-tau), phospho-tau (P181-tau), and their ratios with β-amyloid (Aβ1-42). Adjusted analyses considered age, cognition, APOE ε4 status, education, and sex as covariates. We measured OI using the University of Pennsylvania Smell Identification Test and cognitive performance using the Repeatable Battery for Assessment of Neuropsychological Status. Standard kits provided assays of the AD biomarkers. Analyses used robust-fit linear regression models. ...
Of all our senses, smell is the most mysterious. Yet, despite our lack of understanding, it seems that the nose knows when there is something wrong with the brain. It is now clear that loss of the sense of smell is an early marker for Parkinsons disease and other neurodegenerative conditions. Simple smell tests can help clinicians diagnose Parkinsons more accurately, and a series of recent studies further suggest that they could be used to sniff out at-risk patients earlier.. First described in 1871, Parkinsons is chiefly thought of as a movement disorder characterized by slow movements, rigidity, and tremor. It is becoming increasingly clear, however, that Parkinsons also involves various non-motor symptoms, including cognitive impairment, sleep disturbances, and altered smell, taste, and vision. Clinicians recognized that Parkinsons involves loss of the sense of smell in the 1970s, but reliable tests for olfactory dysfunction did not become available until the mid-1980s. The development ...
Smoking also tends to leave an oily residue on other surfaces, which can contribute to a lingering smoke smell even if you vacuum and use absorbent materials like baking soda and activated charcoal. HEPA: This type of air filter is rated to use mechanical filtration to capture 99.97% of particles 0.3 microns in size, which includes some smoke particles. Leave them for a day and replace them if the smell lingers. Carpet is a sponge for odors and should be replaced, along with any furniture that is still in the house. Luckily, there are ways to fix this. Smelling Cigarette Smoke (Phantosmia): What could it mean? Find a smoke remediation specialist through websites such as Yelp, or ask for referrals from your local home improvement center. The smells vary from person to person but are usually unpleasant, such as burnt toast, metallic, or chemical smells. The smell of cigarette smoke, when there is no odor present, can be an indication that a persons olfactory nerve has been damaged in some way. If ...
A unifying feature of mammalian and insect olfactory systems is that olfactory sensory neurons (OSNs) expressing the same unique odorant-receptor gene converge onto the same glomeruli in the brain [1-7]. Most odorants activate a combination of receptors and thus distinct patterns of glomeruli, forming a proposed combinatorial spatial code that could support discrimination between a large number of odorants [8-11]. OSNs also exhibit odor-evoked responses with complex temporal dynamics [11], but the contribution of this activity to behavioral odor discrimination has received little attention [12]. Here, we investigated the importance of spatial encoding in the relatively simple Drosophila antennal lobe. We show that Drosophila can learn to discriminate between two odorants with one functional class of Or83b-expressing OSNs. Furthermore, these flies encode one odorant from a mixture and cross-adapt to odorants that activate the relevant OSN class, demonstrating that they discriminate odorants by using the
The impact of health, management, and microbiota on olfactory function in canines has not been examined in review. The most important characteristic of the detection canine is its sense of smell. Olfactory receptors are primarily located on the ethmoturbinates of the nasal cavity. The vomeronasal organ is an additional site of odor detection that detects chemical signals that stimulate behavioral and/or physiological changes. Recent advances in the genetics of olfaction suggest that genetic changes, along with the unique anatomy and airflow of the canine nose, are responsible for the macrosmia of the species. Inflammation, alterations in blood flow and hydration, and systemic diseases alter olfaction and may impact working efficiency of detection canines. The scientific literature contains abundant information on the potential impact of pharmaceuticals on olfaction in humans, but only steroids, antibiotics, and anesthetic agents have been studied in the canine. Physical stressors including exercise,

Olfactory identification deficits occur in patients with Alzheimers disease (AD), are associated with disease severity, predict conversion from mild cognitive impairment (MCI) to AD and are associated with healthy elderly subjects developing MCI. Odor (olfactory) identification deficits may reflect degeneration of cholinergic inputs to the olfactory bulb and other olfactory brain regions. Acetylcholinesterase inhibitors (ACheI) like donepezil show modest effects in improving cognition but can be associated with adverse effects and increased burden and costs because of the need for prolonged, often lifelong, treatment. Converging findings on odor identification test performance (UPSIT, scratch and sniff 40-item test) from four pilot studies, including two of our own, suggest that acute change in the UPSIT in response to an anticholinergic challenge (atropine nasal spray), incremental change over 8 weeks, and even the baseline UPSIT score by itself, may predict cognitive improvement with ACheI ...

New televisions may produce an unusual smell or odor when first turned on. Due to the manufacturing process of components, televisions and other electronic products can have parts with plastic coatings that may produce a smell after the product is first turned on and warms up. The smell will usually dissipate within days of use and does not return. This is normal and occurs with many electronic products.. NOTE: If the smell continues to linger even after the television has been turned off, ensure there is sufficient ventilation around the TV and in the room and the odor will dissipate. ...

It has been demonstrated that when exposed to Androstadienone, women let go of stress and discomfort, followed by a feeling of well being. Multiple studies have shown this mood elevating reaction. It has also been said that it eases the symptoms of PMS as well as headaches in women. Another study that was attempting to determine if Androstadienone exposed women would be able to withstand greater levels of pain due to the relaxed Androstadienone induced state, discovered that exactly the opposite was true. Consequently, they accidentally demonstrated that Androstadienone increased the skin sensitivity of women due to a heightened state of arousal. The above mentioned study demonstrates that exposure to Androstadienone increases a womans sense of pleasure when being touched. It has been demonstrated that women exposed to Androstadienone judge men as more attractive than when they have not been exposed. It has been known to increase intimacy and comfort, and can also increase caring feelings. ...

The chemical senses of taste and smell play a vital role in conveying information about ourselves and our environment. Tastes and smells can warn against danger and also contribute to the daily enjoyment of food, friends and family, and our surroundings. Over 12% of the US population is estimated to experience taste and smell (chemosensory) dysfunction. Yet, despite this high prevalence, long-term, effective treatments for these disorders have been largely elusive. Clinical successes in other sensory systems, including hearing and vision, have led to new hope for developments in the treatment of chemosensory disorders. To accelerate cures, we convened the Identifying Treatments for Taste and Smell Disorders conference, bringing together basic and translational sensory scientists, health care professionals, and patients to identify gaps in our current understanding of chemosensory dysfunction and next steps in a broad-based research strategy. Their suggestions for high-yield next steps were focused in
Many times after a rain, there is a distinctive odor in the air - a sort of musky smell. This pleasant fragrance is most common in rains that follow a dry spell. If you are a gardener, you may find this smell similar to the smell you sense when you turn over your soil. Good organic soils contain bacteria. One bacterium that is abundant in damp warm soils is actinomycete.. Actinomycetes are a key ingredient in the decomposition of organic materials in the soil. These bacteria thrive when the soil is moist. When the soil dries out, the actinomycetes produce tiny spores. These spores are part of their reproduction cycle. Rain kicks up these spores when the raindrops hit the ground and make them airborne. Air movements then disperse the spores and carry some of the spores to our nose, where we detect a pleasant aroma. Actinomycetes are very common, which is why you experience the pleasing after-the-rain smell in many locations.. Winds can transport odors from areas upwind of you. We also can ...
One thing I hate to read about is a musky man - partly because its become hackneyed, and partly because the word conjures its original use. The musky scent in colognes used to come from a glandular secretion from near the musk deers rectum. According to Wikipedia, the word musk originates from the Sanskrit for testicle.. Mmmm, picture that next time you cuddle up with your musky historical romance hero. He smells like deer butt.. There are so many more interesting scents for a man, and if you do a bit of research you can make your hero sound intriguing and sexy.. 1. Do you want him to smell natural or synthetic?. You might not want your hero to reek of cologne, but I cant think of many pleasant descriptions of mens natural scents. (Maybe you can help me out by leaving a comment.) It seems much easier to describe the scent of a villain than a hero.. There are a few factors that can affect the way people smell. Men can pick up different smells depending on their job.

We have always spoken about the surface, texture, size and the possible threat of a comet. But have we ever thought about how a comet smells like when its tearing around in space?. Scientists have discovered a new comet that possesses strong foul smell of horse stable (ammonia), of rotten eggs (hydrogen sulphide) and the pungent and very suffocating odor of formaldehyde.. The name of this foul smelling comet is 67P/Churyumov-Gerasimenko.. The discovery was made by the scientists at the University of Bern in Switzerland through the Rosetta Orbiter Spectrometer for Ion and Neutral Analysis that has been sniffing the fumes of the strange celestial body with the help of its two mass spectrometers.. The scientists said they had determined about the smell of the comet by analysing the chemicals in its coma, the fuzzy head that surrounds the nucleus.. According to the scientists, the strong smell of the comet is mixed with the bitter, faint and hydrogen cyanides almond-like aroma. The comet also has ...
While general grossness and the sewer tunnels both figure in as possible explanations, the Keyser Soze of the mystery smell might actually be a set of organic brake pads the agency once ordered for its trains. According to this explanation, popular among online Metro obsessives, the agencys attempt to go green backfired when new brakes it installed started emitting the dead-fish smell train passengers know so well. This explanation is backed up by a customer service message from Metro, posted on Metro-tracking blog Unsuck D.C. Metro in September, which blamed the smell on the brake pads. The agency had already decided not to reorder them, according to the customer service employee, but was trying to go through its supply first. Metro later denied that the brake pads were still in use. Will this mystery ever be solved? Maybe not until the smell comes back. Metro spokesman Dan Stessel claims that the organic brake pads havent been used for years. When Ive gone down this road in the past, ...
Odor perception is a complex process involving the central nervous system and can evoke psychological and physiological responses. Because the olfactory signal terminates in or near the amygdala, odors are strongly linked to memories and can evoke emotions. The amygdala participates in the hedonic or emotional processing of olfactory stimuli.[45] Odors can disturb our concentration, diminish productivity, evoke symptoms, and in general increase a dislike for an environment. Odors can impact the liking for a person, place, food, or product as a form of conditioning.[46] Memories recalled by odors are significantly more emotional and evocative than those recalled by the same cue presented visually or auditorily.[47] Odors can become conditioned to experiential states and when later encountered have directional influences on behavior. Doing a frustrating task in a scented room decreases performance of other cognitive tasks in the presence of the same odor.[48] Nonhuman animals communicate their ...
Through what they claim is the largest genome-wide association study (GWAS) of olfactory genes, researchers in Iceland have identified genetic variants that affect how people perceive the strength and unpleasantness of fish odor. Many people find the smell of fish strong and unpleasant, but the new study-which involved more than 9,000 people in Iceland, and a sniff test-showed how some people carry a mutation in a particular gene that makes fish odor less intense. The researchers also identified other gene mutations that impact on the ability to discern the smell of licorice, and cinnamon.. We discovered sequence variants that influence how we perceive and describe fish, licorice, and cinnamon odors, said Rosa Gisladottir, PhD, from deCODE Genetics and the University of Iceland, who is first and co-corresponding author of the teams published paper in Current Biology. Since our sense of smell is very important for the perception of flavor, these variants likely influence whether we like food ...

We purchased a 5th wheel trailer that an older person and their dog had lived in for about 2 years. The trailer was only 2 1/2 years old, but the couches smelled of urine (not sure if human or dog) and in their attempt to cover the smell up, it smells like they used perfume of some sort on the cushions.. 1.We had the couches steam cleaned by a carpet cleaning company. RESULTS: Reduced smell by 50% but still smelled.. 2. Let everything air out for about 60 days. RESULTS: No real reduction in smell.. 3. Removed the covers from cushions and had covers dry cleaned. RESULTS: Perfume smell gone, urine smell still strong.. 4. Cushion foam washed in clorox solution and dried. RESULTS: Cushions odor free.. 5. Sprayed a cushion cover with white vinager and let dry. RESULTS: Urine smell still detectable.. Do you feel one of your products will take out the smell? If so I could place the cushion covers in a plastic bag for a period of time with the proper product you might recommend. As for the couch backs, ...
We supplemented our knowledge of the smell terms in Jahai and Maniq by using free-listing: we simply asked people to list all the smell words they knew. In addition, we tried to find out more about their application by asking people to provide exemplars (What smells like X?) for each of the smell words. With the Maniq, we also conducted a similarity judgment task. We wanted to understand better the how the smell words were related to one another. So, we provided Maniq speakers with triads of smell words, and asked them to tell us which word was the most different to the others. It would be like asking English speakers to say which is the most different out of the following three: GREEN, BLUE, ORANGE. These judgments can be converted into similarity matrices, and then analysed using multivariate statistics to reveal the underlying structure of the smell lexicon.. These empirical methods are one prong of our smell studies. We also rely on linguistic elicitation to figure out more about the ...
A temporary loss of smell can be caused by a blocked nose or infection. In contrast, a permanent loss of smell may be caused by death of olfactory receptor neurons in the nose or by brain injury in which there is damage to the olfactory nerve or damage to brain areas that process smell (see olfactory system). The lack of the sense of smell at birth, usually due to genetic factors, is referred to as congenital anosmia. Family members of the patient suffering from congenital anosmia are often found with similar histories; this suggests that the anosmia may follow an autosomal dominant pattern.[7] Anosmia may very occasionally be an early sign of a degenerative brain disease such as Parkinsons disease and Alzheimers disease. Another specific cause of permanent loss could be from damage to olfactory receptor neurons because of use of certain types of nasal spray; i.e., those that cause vasoconstriction of the nasal microcirculation. To avoid such damage and the subsequent risk of loss of smell, ...
The potential uses of smell technology are endless, notes Josep Samitier, the coordinator of the SPOT-NOSED project that developed nanobiosensors to mimic the way human and animal noses respond to different odours. This new nose biosensor is unusual in how its made. By placing a layer of proteins that constitute the olfactory receptors in animal noses on a microelectrode and measuring the reaction when the proteins come into contact with different odorants, the system is capable of detecting odorants at concentrations that would be imperceptible to humans.. Our tests showed that the nanobiosensors will react to a few molecules of odorant with a very high degree of accuracy. Some of the results of the trials surpassed even our expectations, Samitier says. These tiny bioelectronic sensors, he says, represent a major leap forward in smell technology and a clear example of a biomimetic devices obtained by converging Nano-Bio-Info technologies.. Several hundred different proteins, which the ...

Li backed up these findings with scans of the volunteers brains. She used a technique called functional magnetic resonance imaging (fMRI) to show that their learning experiences were mirrored by changes in their posterior piriform cortex (PPC), a part of the brain involved in learning new smells. At the start of the study, sniffing both forms of 2-butanol triggered similar patterns of activity in the PPC. After the shock, these patterns became more distinct, even though the overall level of activity in the region stayed the same. In contrast, the patterns for the rose oxide molecules remained strongly coupled throughout the study. Adaptive sniffing Weve known for decades that a shocking stimulus can condition an animal towards certain types of behaviour, but this study clearly shows that it can also make an animal more sensitive to the stimulus in question. Clearly, animals benefit from being able to discern the smell of danger and ignore unimportant odours. As Li herself put it, the whiff of ...
Steven D. Munger, University of Florida. Each of our senses gives us a unique view of our world. Our visual system detects parts of the electromagnetic spectrum, revealing movement, brightness and color, but also a smile or a tear. Our auditory system registers changes in pressure, but also allows us to hear the crash of ocean waves or the smoky contralto of Billie Holiday. To appreciate the flavor of food and drink, recognize the perfume of the first spring flowers or detect the danger of a gas leak, we rely upon our olfactory (smell) and gustatory (taste) systems.. Smell and taste are intimately linked to each other. They are collectively known as chemical senses because each system functions to detect chemicals in our external environment. Our brains also process aspects of smell and taste together, especially when it comes to perceiving the flavor of food.. The chemical senses play hugely important roles in the lives of all animals. For example, a recent pair of studies showed that social ...

If the physician determines a patients loss of smell to be caused by allergies or other inflammatory diseases, he/she may recommend nasal or oral steroids and antihistamines to decrease the inflammation. Surgery may be suggested if the patient is found to have nasal polyps, chronic sinusitis, deviated septum, or other surgically treatable disorders. However, our knowledge in recommending surgery to improve olfaction is limited, as there is no good evidence currently to suggest either surgery or medical management has a better outcome with regard to smelling ability. As mentioned before, despite medical or surgical treatments, certain inflammatory diseases like chronic rhinosinusitis can cause permanent loss, and return of smell to a totally normal state may not be possible. Although there is some controversy, many patients who have obstructive causes for their loss of smell usually do report significant improvements after both medical and surgical treatments. Patients with a permanent loss of ...
The purpose of this agreement is to provide funding for a collaborative effort with the National Center for Health Statistics (NCHS) to pilot test the chemosenses component in persons age 40 and older, and implement in the survey pending a successful pilot. The chemosenses component will consist of 1) household interview questions to define the prevalence of self-reported taste and smell disorders, and to identify risk factors and confounders for the analysis of the taste and smell exam data; 2) smell testing using two modified Pocket Smell Identification Tests, a scratch and sniff test with 8 odorants; and 3) taste testing performed using small amounts of liquids that can be spit out afterwards. For Taste testing, the respondent will be asked both to identify and to rate the intensity of the stimulus. (ADC12002001-1-0-0) ...

People often talk with some drama about the smell of fear, and yet who among us could describe what the odour is like?

The New Caledonian languages branched off from the other Oceanic languages after Melanesian people settled in New Caledonia around 3000 bc. The languages evolved under mostly isolated conditions until there was contact with Europeans in the late 18th century which created regular contact form the subsequent trading, migration and eventual colonization. Protestant and Roman Catholic missionaries arrived in New Caledonia in the 1840s and began efforts at conversion; most notably for the north province was Marist mission was set up just north of Pouebo, in Balade. The French took colonial possession of most of New Caledonia in 1853 and imposed forced labor, limitations on travel, and curfews which lead to Melanesian revolts that were a frequent occurrence until 1917. By 1860 the French had established their authority over the southern part of the mainland and implemented policies that significantly destabilized and altered the lives of Melanesians, including: the confiscation and dispossession of ...
