Distinct signaling pathways mediate touch and osmosensory responses in a polymodal sensory neuron. (1/1361)

The Caenorhabditis elegans ASH sensory neurons mediate responses to nose touch, hyperosmolarity, and volatile repellent chemicals. We show here that distinct signaling pathways mediate the responses to touch and hyperosmolarity. ASH neurons distinguish between these stimuli because habituation to nose touch has no effect on the response to high osmolarity or volatile chemicals (1-octanol). Mutations in osm-10 eliminate the response to hyperosmolarity but have no effect on responses to nose touch or to volatile repellents. OSM-10 is a novel cytosolic protein expressed in ASH and three other classes of sensory neurons. Mutations in two other osmosensory-defective genes, eos-1 and eos-2, interact genetically with osm-10. Our analysis suggests that nose touch sensitivity and osmosensation occur via distinct signaling pathways in ASH and that OSM-10 is required for osmosensory signaling.  (+info)

The distribution of zinc selenite and expression of metallothionein-III mRNA in the spinal cord and dorsal root ganglia of the rat suggest a role for zinc in sensory transmission. (2/1361)

Zinc appears to play a role in synaptic transmission in the hippocampus. We tested the hypothesis that zinc is similarly involved in sensory transmission by determining whether vesicular zinc and metallothionein-III (MT-III), a zinc-binding protein, are localized in rat primary afferent neurons. MT-III mRNA, measured using RT-PCR, and MT-III immunoreactivity, were both present in the spinal cord as well as the thoracic and lumbar dorsal root ganglia (DRG). At a time (24 hr) that allows retrograde transport of zinc selenite to cell bodies, only small-diameter neurons and neurons scattered throughout lamina V of the spinal cord were stained by sodium selenite injected intrathecally. This stain disappeared if a ligature was placed on the dorsal root to block axonal transport, demonstrating that these cells are, in fact, zinc-containing primary afferent neurons. When assessed 1 hr after sodium selenite, stain was distributed throughout the neuropil of the spinal cord, especially in lamina III and the area surrounding the central canal. Even in rhizotomized animals, large- and small-diameter DRG neuronal cell bodies were also stained with either selenite (1 hr) or 6-methoxy 8-para-toluene sulfonamide quinoline (TSQ). Paradoxically, this unique pool of zinc was eliminated in large-diameter DRG neurons after neonatal capsaicin treatment, which had no effect on selenite stain or MT-III mRNA content in small-diameter DRG neurons. In summary, we demonstrate that there is a population of capsaicin-insensitive small-diameter primary afferent neurons that are zinc-containing. In addition, there is a unique pool of capsaicin-sensitive zinc that is associated with large-diameter cell bodies.  (+info)

Effects of duodenal distension on antropyloroduodenal pressures and perception are modified by hyperglycemia. (3/1361)

Marked hyperglycemia (blood glucose approximately 15 mmol/l) affects gastrointestinal motor function and modulates the perception of gastrointestinal sensations. The aims of this study were to evaluate the effects of mild hyperglycemia on the perception of, and motor responses to, duodenal distension. Paired studies were done in nine healthy volunteers, during euglycemia ( approximately 4 mmol/l) and mild hyperglycemia ( approximately 10 mmol/l), in randomized order, using a crossover design. Antropyloroduodenal pressures were recorded with a manometric, sleeve-side hole assembly, and proximal duodenal distensions were performed with a flaccid bag. Intrabag volumes were increased at 4-ml increments from 12 to 48 ml, each distension lasting for 2.5 min and separated by 10 min. Perception of the distensions and sensations of fullness, nausea, and hunger were evaluated. Perceptions of distension (P < 0.001) and fullness (P < 0.05) were greater and hunger less (P < 0.001) during hyperglycemia compared with euglycemia. Proximal duodenal distension stimulated pyloric tone (P < 0.01), isolated pyloric pressure waves (P < 0.01), and duodenal pressure waves (P < 0.01). Compared with euglycemia, hyperglycemia was associated with increases in pyloric tone (P < 0.001), the frequency (P < 0.05) and amplitude (P < 0.01) of isolated pyloric pressure waves, and the frequency of duodenal pressure waves (P < 0.001) in response to duodenal distension. Duodenal compliance was less (P < 0.05) during hyperglycemia compared with euglycemia, but this did not account for the effects of hyperglycemia on perception. We conclude that both the perception of, and stimulation of pyloric and duodenal pressures by, duodenal distension are increased by mild hyperglycemia. These observations are consistent with the concept that the blood glucose concentration plays a role in the regulation of gastrointestinal motility and sensation.  (+info)

Physiological changes in blood glucose do not affect gastric compliance and perception in normal subjects. (4/1361)

Marked hyperglycemia (blood glucose approximately 14 mmol/l) slows gastric emptying and affects the perception of sensations arising from the gut. Elevation of blood glucose within the physiological range also slows gastric emptying. This study aimed to determine whether physiological changes in blood glucose affect proximal gastric compliance and/or the perception of gastric distension in the fasting state. Paired studies were conducted in 10 fasting healthy volunteers. On a single day, isovolumetric and isobaric distensions of the proximal stomach were performed using an electronic barostat while the blood glucose concentration was maintained at 4 and 9 mmol/l in random order. Sensations were quantified using visual analog scales. The blood glucose concentration had no effect on the pressure-volume relationship during either isovolumetric or isobaric distensions or the perception of gastric distension. At both blood glucose concentrations, the perceptions of fullness, nausea, bloating, and abdominal discomfort, but not hunger or desire to eat, were related to intrabag volume (P +info)

Interstitial Ca2+ undergoes dynamic changes sufficient to stimulate nerve-dependent Ca2+-induced relaxation. (5/1361)

We recently described a perivascular sensory nerve-linked dilator system that can be activated by interstitial Ca2+ (Ca2+isf). The present study tested the hypothesis that Ca2+isf in the rat duodenal submucosa varies through a range that is sufficient to activate this pathway. An in situ microdialysis method was used to estimate Ca2+isf. When the duodenal lumen was perfused with Ca2+-free buffer, Ca2+isf was 1.0 +/- 0.13 mmol/l. Ca2+isf increased to 1.52 +/- 0.04, 1.78 +/- 0.10, and 1.89 +/- 0.1 when the lumen was perfused with buffer containing 3, 6, and 10 mmol/l Ca2+, respectively (P < 0.05). Ca2+isf was 1.1 +/- 0.06 mmol/l in fasted animals and increased to 1. 4 +/- 0.06 mmol/l in free-feeding rats (P < 0.05). Wire myography was used to study isometric tension responses of isolated mesenteric resistance arteries. Cumulative addition of extracellular Ca2+-relaxed serotonin- and methoxamine-precontracted arteries with half-maximal effective doses of 1.54 +/- 0.05 and 1.67 +/- 0.08 mmol/l, respectively (n = 5). These data show that duodenal Ca2+isf undergoes dynamic changes over a range that activates the sensory nerve-linked dilator system and indicate that this system can link changes in local Ca2+ transport with alterations in regional resistance and organ blood flow.  (+info)

The neural consequences of conflict between intention and the senses. (6/1361)

Normal sensorimotor states involve integration of intention, action and sensory feedback. An example is the congruence between motor intention and sensory experience (both proprioceptive and visual) when we move a limb through space. Such goal-directed action necessitates a mechanism that monitors sensorimotor inputs to ensure that motor outputs are congruent with current intentions. Monitoring in this sense is usually implicit and automatic but becomes conscious whenever there is a mismatch between expected and realized sensorimotor states. To investigate how the latter type of monitoring is achieved we conducted three fully factorial functional neuroimaging experiments using PET measures of relative regional cerebral blood flow with healthy volunteers. In the first experiment subjects were asked to perform Luria's bimanual co-ordination task which involves either in-phase (conditions 1 and 3) or out-of-phase (conditions 2 and 4) bimanual movements (factor one), while looking towards their left hand. In half of the conditions (conditions 3 and 4) a mirror was used that altered visual feedback (factor two) by replacing their left hand with the mirror image of their right hand. Hence (in the critical condition 4) subjects saw in-phase movements despite performing out-of-phase movements. This mismatch between intention, proprioception and visual feedback engendered cognitive conflict. The main effect of out-of-phase movements was associated with increased neural activity in posterior parietal cortex (PPC) bilaterally [Brodmann area (BA) 40, extending into BA 7] and dorsolateral prefrontal cortex (DLPFC) bilaterally (BA 9/46). The main effect of the mirror showed increased neural activity in right DLPFC (BA 9/ 46) and right superior PPC (BA 7) only. Analysis of the critical interaction revealed that the mismatch condition led to a specific activation in the right DLPFC alone (BA 9/46). Study 2, using an identical experimental set-up but manipulating visual feedback from the right hand (instead of the left), subsequently demonstrated that this right DLPFC activation was independent of the hand attended. Finally, study 3 removed the motor intentional component by moving the subjects' hand passively, thus engendering a mismatch between proprioception and vision only. Activation in the right lateral prefrontal cortex was now more ventral than in studies 1 or 2 (BA 44/45). A direct comparison of studies 1 and 3 (which both manipulated visual feedback from the left hand) confirmed that a ventral right lateral prefrontal region is primarily activated by discrepancies between signals from sensory systems, while a more dorsal area in right lateral prefrontal cortex is activated when actions must be maintained in the face of a conflict between intention and sensory outcome.  (+info)

Quantitative and selective assessment of sensory block during lumbar epidural anaesthesia with 1% or 2% lidocaine. (7/1361)

We have examined sensory block during lumbar epidural anaesthesia using a cutaneous current perception threshold (CPT) sensory testing device in 20 patients who received 10 ml of either 1% or 2% lidocaine (lignocaine). CPT at 2000, 250 and 5 Hz stimulation at the trigeminal (V), ninth thoracic (T9) and second lumbar (L2) dermatomes, and dermatomal levels of block to light touch, temperature and pinprick discrimination were measured before and every 5 min until 60 min after epidural lidocaine. There were significant differences between 1% and 2% epidural lidocaine in all CPT at T9 and L2, in addition to maximal cephalad spread of the three sensory modalities. After 2% lidocaine, all CPT increased significantly at T9 and L2. In contrast, only at 250 and 5 Hz for L2 did epidural block with 1% lidocaine produce significant increases in CPT. Maximal level of loss of touch sensation after 1% lidocaine was significantly lower than that of cold and pinprick sensations. We conclude that the dose of lidocaine affected intensity of sensory block during lumbar epidural anaesthesia. In addition, differential neural block resulting from epidural anaesthesia appeared to be associated with a differential effect on nerve fibres of different sizes.  (+info)

External thoracic restriction, respiratory sensation, and ventilation during exercise in men. (8/1361)

Multiple factors may contribute to the dyspnea associated with restrictive ventilatory disease (RVD). Simple models that examine specific features of this problem are likely to provide insight into the mechanisms. Previous models of RVD utilizing elastic loads may not represent completely the impact on pulmonary and chest wall receptors derived from breathing at low thoracic volumes. The purpose of this study was to investigate the sensory consequences of breathing at low lung volumes induced by external thoracic restriction in an attempt to further elucidate the etiology of dyspnea in this setting. Ten men were studied, with and without an inelastic corset applied at residual volume (restriction resulted in mean reductions in vital capacity, functional residual capacity, residual volume, and forced expired volume in 1 s of 44, 31, 12.5, and 42%, respectively). During 10-min steady-state exercise tests (at a workload set to achieve approximately 65% maximum heart rate), restriction resulted in significant increases, compared with control, in minute ventilation (61 vs. 49 l/min), respiratory frequency (43 vs. 23 breaths/min), and visual analog scale measurements of respiratory discomfort (65 vs. 20 mm). Alveolar hyperventilation (end-tidal PCO2 = 39 vs. 44 Torr for control) and mild O2 desaturation (arterial blood O2 saturation = 93 vs. 95% for control) occurred. Hypoxemia, atelectasis, increased work and effort of breathing, or a decrease in the volume-related feedback from chest wall and/or lungs could be responsible for the increased dyspnea reported. External thoracic restriction provides a useful model to study mechanisms of dyspnea in RVD.  (+info)

Erotic sensation play is a class of activities meant to impart physical sensations upon a partner, as opposed to mental forms of erotic play such as power exchange or sexual roleplaying. Sensation play can be sensual, where the sensations are generally pleasing and light. Many couples that would not consider themselves active in BDSM are familiar with this kind of play: the use of silk scarves, feathers, ice, massage oils, and other similar implements. Sensation play in BDSM can also involve sadomasochistic play, involving the application of carefully controlled stimuli to the human body so that it reacts as if it were actually hurt. While this can involve the infliction of actual pain, it is usually done in order to release pleasurable endorphins, creating a sensation somewhat like runners high or the afterglow of orgasm, sometimes called flying or body stress. In BDSM play, the top (or dominant) introduces and controls the sensation to the bottom (or submissive). Two partners exploring ...

The present study examined the relationship between personality and individual differences in multi-tasking ability. Participants enrolled at the University of Utah completed measures of multi-tasking activity, perceived multi-tasking ability, impulsivity, and sensation seeking. In addition, they performed the Operation Span in order to assess their executive control and actual multi-tasking ability. The findings indicate that the persons who are most capable of multi-tasking effectively are not the persons who are most likely to engage in multiple tasks simultaneously. To the contrary, multi-tasking activity as measured by the Media Multitasking Inventory and self-reported cell phone usage while driving were negatively correlated with actual multi-tasking ability. Multi-tasking was positively correlated with participants perceived ability to multi-task ability which was found to be significantly inflated. Participants with a strong approach orientation and a weak avoidance orientation - high levels of

BACKGROUND: Sensation-seeking is a trait that constitutes an important vulnerability factor for a variety of psychopathologies with high social cost. However, little is understood either about the mechanisms underlying motivation for intense sensory experiences or their neuropharmacological modulation in humans. METHODS: Here, we first evaluate a novel paradigm to investigate sensation-seeking in humans. This test probes the extent to which participants choose either to avoid or self-administer an intense tactile stimulus (mild electric stimulation) orthogonal to performance on a simple economic decision-making task. Next we investigate in a different set of participants whether this behavior is sensitive to manipulation of dopamine D2 receptors using a within-subjects, placebo-controlled, double-blind design. RESULTS: In both samples, individuals with higher self-reported sensation-seeking chose a greater proportion of mild electric stimulation-associated stimuli, even when this involved sacrifice of

The skin is a human beings largest sensory organ, helping to distinguish between a pleasant contact, like a caress, and a negative sensation, like a pinch or a burn. Previous studies have shown that these sensations are carried to the brain by different types of sensory neurons that have nerve endings in the skin. Now biologists at Caltech have identified in mice a specific class of skin sensory neurons that reacts to an apparently pleasurable stimulus.
A subjective evaluation experiment under the standard dynamic range (SDR) condition was past conducted on the purpose of verifying relationships between angular resolution images and a sensation of realness such that real objects are there. The results revealed that the sensation of realness monotonically increases up to 60 cpd (cycles per degree) which is equivalent to two pixels per minute in the angle of sight and then it becomes saturated above 60 cpd. The sensation of realness under the high dynamic range (HDR) condition has not yet been studied, it has possibility such that the relationships between angular resolution and the sensation of realness varies by the HDR effect. Hence, we conducted a subjective evaluation experiment to examine whether the angular resolution at which the sensation of realness becomes saturated can vary according to the dynamic range. The results indicate that there is a reproducibility of previous experiments results and the angular resolution at which the ...
The first handset to feature Beats Audio has officially been announced straight from HTCs Headquarter, and they are calling the device as HTC Sensation XE. And as youd guess, HTC Sensation XE will carry the same hardware specs as the first dual-core smartphone of the company, except that it got a faster processor at 1.5GHz, which definitely more than just enough to power all your apps in Android Gingerbread. It flaunts the same 4.3-inch capacitive display; this time however, its more vivid with qHD resolution. Plus, theres an option to add external storage up to 16GB through microSD, so you got plenty of space for your favorite multimedia files. And since this phone is expected to deliver Hi-Fi and studio quality audio on top of the powerful processor and vibrant display, HTC increased a few more Coulombs to HTC Sensations power source, this time with 1,730 mAh battery, so HTC Sensation XE wont drain power that fast.

Sensory nerves. Peripheral neuropathy usually affects your sense of touch and feeling in the nerves in the hands and feet. Most people with cancer who develop neuropathy feel tingling, burning, a buzzing electrical sensation, or numbness. It usually starts in the toes and fingers and can continue along the hands and feet toward the center of the body. You may feel as though youre wearing tight gloves or stockings, even though you arent. Nerve damage may also result in an uncomfortable sensation in your hands or feet that may be worse when you touch something. In addition, objects on your feet that usually arent painful, such as a shoe or bedcovers, may cause pain. You may notice an overall heightened sense of pain; the painful sensations are commonly described as pinching, sharp stabs, burning, and electrical shocks. You may notice a loss of sensation, making it difficult to feel hot and cold temperatures or to know if youve injured yourself. Another symptom is loss of position sense, ...
EPFL researchers have discovered that the human brain suppresses the sensory effects of the heartbeat. They believe that this mechanism prevents internal sensations from interfering with the brains perception of the external world. This mechanism could also have something to do with anxiety disorders.. Our heart is constantly beating yet we normally do not feel it. It turns out that our brain is capable of filtering out the cardiac sensation so that it doesnt interfere with the brains ability to perceive external sensations. For the first time, researchers from the Center for Neuroprosthetics at EPFL have identified this mechanism. They discovered that a certain region in the brain determines where internal and external sensations interact. Their work appears in The Journal of Neuroscience.. EPFLs neuroscientists noted that the brain perceives visual stimuli less effectively if they occur in time with the heartbeat. It seems as if the brain wants to avoid processing information that is ...

I would strongly contend that embodiment/disembodiment are central problems in trauma treatment. The felt self and sensations are only a partial approach to the problem. The purpose of embodiment, whether from conditions of trauma or not, is to restore vitality and integration, again and again. The out of contact state resulting from trauma demands being in touch but also being touched to find the way home again. This is where somatic based psychotherapies are crucial because they are based on fully experiencing oneself, ones own ground, centeredness and personhood, beyond the limitations of words and information processing. (IIBA Clinical Journal 17 - p29) (2007) David Finlay. It is interesting to note that recent developments in the field of trauma also confirm the importance of including the body in the therapeutic process. For instance, in trauma recovery work, lower-brain processing and the awareness of body sensations are key features of the sensorimotor techniques of Peter ...
Corneal sensitivity measured using a mechanical stimulus is depressed in diabetic subjects and the extent of any depressed sensitivity is related to the duration of the disease process according to Saini and Khandalavla. 35 This result conflicts with the conclusion reached by Inoue et al. 34 We did not find any association between corneal sensitivity and time since diagnosis of diabetes thus, confirming the latter study. We also agree with the results of ODonnell et al. 38 in not finding any difference in corneal sensitivity between the diabetic subjects and the nondiabetic subjects. It could be argued that we did not detect a reduced sensitivity using NCCA, because the diabetes in our subjects was of relatively short duration. On average, the diabetes in our subjects had been confirmed 9.3 ± 7.1 years (range, 1-43 years) earlier. We would expect a change in sensitivity subsequent to diagnosis of the disease, but this was not the case. For our protocol, we purposefully excluded subjects with ...

RLS is described by patients as the experience of vague or unpleasant sensations involving usually the lower extremities, but sometimes the upper extremities. This discomfort appears primarily during periods of inactivity, particularly during the transition from wake to sleep, or during the day, sitting on a plane, lone car rides, or sitting in a movie theater. RLS patients often have difficulty describing the sensations, rarely using conventional terms of discomfort such as numbness, tingling, or pain, but rather bizarre terms such as pulling, searing, drawing, creepy, crawly, fluttering, shimmering, butterflies, or boring sensations, with the sensations often causing anxiety. Distinct from sensory neuropathy patients, these unpleasant sensations are typically relieved by movement or counter stimulation (rubbing, massaging, hot water) of the affected part. Although, these manoeuvers are effective while being performed, the discomfort returns as soon as the individual becomes inactive or ...

Peripheral neuropathy is a widespread and potentially incapacitating pathological condition that encompasses more than 100 different forms and manifestations of nerve damage. The diverse pathogenesis of peripheral neuropathy affects autonomic, motor and/or sensory neurons, and the symptoms that typify the condition are abnormal cutaneous sensation, muscle dysfunction and, most notably, chronic pain. Chronic neuropathic pain is difficult to treat and is often characterized by either exaggerated responses to painful stimuli (hyperalgesia) or pain resulting from stimuli that would not normally provoke pain (allodynia). The objective of this review is to provide an overview of some pathways associated with the development of peripheral neuropathy and then discuss the benefits of exercise interventions. The development of neuropathic pain is a highly complex and multifactorial process, but recent evidence indicates that the activation of spinal glial cells via the enzyme glycogen synthase kinase 3 and
Touch (#5) requires elaboration. Touch (for our purposes) will also include the sensations of pain and temperature (hot/cold). When there is a perturbation on our skin, we readily can distinguish between touch, pain, hot, and/or cold. All of these sensations are electrical signals that travel to various parts of the brain for interpretation.. The important point is that all perceptions (sight, sound, taste, smell, touch [including pain and temperature] and proprioception) occur in the cortical brain. All perceptions are cortical. This means that they occur in our brain. Lay people often believe that their eye sees, their ear hears, their tongue tastes, their nose smells, or that something at their toe or back or neck hurts. But actually these various parts of our body only initiate an electrical signal that is then interpreted in our brain.. •••••. The cortical perception of pain is a universal human experience. The electrical signal for the perception of pain in the brain is brought ...

Connective tissue stimulation. A lot of therapists are keen on stretching connective tissues - tendons, ligaments, and layers of Saran wrap-like tissue called fascia. Im not a huge fan of this style, but certainly its a way of generating many potent and novel sensations, which may be inherently valuable to us - another form of touch. Although improving the fascia itself is implausible and unproven, perhaps fascial manipulations affect bodies indirectly, just as a sailboat is affected by pulling on its rigging. People have written whole books full of speculation along these lines. So, as long as the sensations are not like skin tearing (thats an ugly pain for sure), you might choose to tolerate this kind of massage if it seems to be helping you ...
Did you know that, our sense of smell has a unique way of doing it - since it follows an opposite path. Smell sensations are relayed to the cerebral cortex only after the deepest parts of our brain have been stimulated. In other words, incoming aromas first trigger an emotional response, which is then followed by cognitive recognition. (w.Garner) This means an emotional connection has been made long before your mind even recognizes what the smell is..

tingling hands is extremely common and bothersome at the same time. Such sensations are mostly harmless and only temporary. For an instance, it could be a result from the pressure on the nerves when you place your arm under your head as you sleep. In this case, the tingling commonly known as pins and needles effect is relieved as soon as removing the pressure that caused it.. Causes of Hand Numbness. Diabetes is among the most common causes of nerve damage, making out for about 30% of all cases. In diabetic neuropathy, numbness and other symptoms often first develop in the feet and go up the legs, followed by numbness and other symptoms that the both hands, then goes up the arms. About 60% of people who suffer diabetes have nerve damages ranging from mild to severe. In most cases, these are the first signs of diabetes.. Numbness in hands can sometimes be caused by compression of the nerve, also known as a pinched nerve. The compression of the nerve usually occurs around the areas where the ...
Tip 3: Eat vegetables first. Eating vegetables causes satiation. Foods that promote satiation (full sensation) are generally very bulky, have a high water and fiber content, and carry strong sensory attributes. It is important to realize that the satiating properties of a food are not just determined by its nutrient (and water) content. Texture is also very important. For example, there is evidence that eating an apple is more satiating than drinking apple juice, even if that apple juice was prepared in a blender using the entire apple. ...
The highly accessible Sensation and Perception presents a current and accurate account of modern sensation and perception from both a cognitive and neurocognitive perspective. To show students the relevance of the material to their everyday lives and future careers, authors Bennett L. Schwartz and John H. Krantz connect concepts to real-world applications, such as driving cars, playing sports, and evaluating risk in the military.

The Second Edition includes a revamped version of the In Depth feature from the previous edition in new Exploration sections that invite readers to learn more about exciting developments in the field. Additionally, new Ponder Further sections prompt students to practice their critical thinking skills with chapter topics. Available Tools and ...
A mobility limiting injury can throw me back down into a mental world of not coping. My body reacts with anxiety before my mind invents a reason to be racing. I have to pay attention to be able to recognise that this is happening, that my physical sensations are guiding my thoughts and that I have the power to let those thoughts go. I have to find the strength to deny the extra pain and incapacitation as a reason to give up and cry. I have to be strong enough to recognise that (in all likelihood) the injury will heal and I will be okay again. I have to be brave enough to trust my body, despite its history of letting me down. Its a lot of thinking and realising and letting go. Its a lot. ...
An intense, green, fruity oil, with clear vegetable notes reminiscent of olive leaves and vegetables (artichokes, tomato plants, etc.). Very strong on the palate and initially very bitter, turning distinctly astringent and ending with a clearly peppery aftertaste. These powerful sensations are correctly balanced by the intensity and complexity of the fruitiness and are highly appreciated when an intense and persistent oil strongly reminiscent of olives is called for..

Dear LinguistList members, another sensation which can kill the previous sensation that Bahtin (wrongly Bakhtin) wrote Medvedevs Formalnyj method...(Formal Method). Our statistical investigations based on the frequency of occurrence of prepositions showed by Chi-sqare test that Bahtin did not write it. We also proved that Voloshinov did not write this conrovercial Medvedevs text. We cannot prove that it was written by Medvedev because we have no other Madvedevs texts. We are sorry that we killed the sensation that Bahtin wrote it UNDER A MASK. If we receive some more Medvedevs texts, we can prove that it was written by Medvedev. Now the conclusion is that neither Bahtin, nor Voloshinov wrote it. How ever, as we wrote in our previous article published in the California Linguistic Notes, Tolstoy wrote Tolstoys texts, Dostoevskiy wrote Dostoevskiys and so on. We analysed about thirty Russian writers. They all showed their own authorship. We are looking forward to your commentaries about ...

CoolSculpting is non-invasive. This means, unlike other weight loss procedures, it does not require incisions, anesthesia, or other medications that could cause allergic reaction or infection. This means the complication rate and rate of side effects is much lower than with more invasive procedures such as liposuction or other surgical procedures.. The most common complication from CoolSculpting is a reduction in sensation in the area where the procedure was performed.. Other common side effects can include:. A tugging sensation at the treatment site- During the procedure, a roll of fat from the part of your body that is being treated is placed between the two cooling panels. This can cause a sensation of pulling or tugging as the machine is moved over the treatment site. Unfortunately, this is something that you will need to tolerate for the duration of the procedure, approximately one to two hours.. Pain, stinging, or aching at the treatment site- Another common side effect of the procedure is ...

The world view of rodents is largely determined by sensation on two length scales. One is within the animals peri-personal space. Sensorimotor control on this scale involves active movements of the nose, tongue, head, and vibrissa, along with sniffing to determine olfactory clues. The second scale involves the detection of more distant space through vision and audition; these detection processes also impact repositioning of the head, eyes, and ears. Here we focus on orofacial motor actions, primarily vibrissa-based touch but including nose twitching, head bobbing, and licking, that control sensation at short, peri-personal distances. The orofacial nuclei for control of the motor plants, as well as primary and secondary sensory nuclei associated with these motor actions, lie within the hindbrain. The current data support three themes: First, the position of the sensors is determined by the summation of two drive signals, i.e., a fast rhythmic component and an evolving orienting component. ...
Sensory Integration. Children with proprioceptive and tactile integration dysfunction can benefit from the sensory feedback they receive from proprioceptive, deep pressure input. Can be used for calming to help the oversensitive child decrease hyper-responsiveness.
Lately I have been noticing that my gfs vagina seems noticeably less tight than when we started dating a year ago. It used to be that I could insert just the head and feel a pleasant gripping sensation, now thats no longer the case - I need to go at least halfway in to feel any significant sensation at all. Thats without a condom too! I dont think its because of my size being too small - just about every girl Ive ever been with has commented on my size being large. Im not hugely long,

This study evaluated the effects of a single dose of pregabalin on colonic sensation and motor function in healthy adults and demonstrated that 200 mg of pregabalin reduces mean gas and pain sensation ratings in response to four random-order phasic distensions over the range of pressures, with the highest pressures reaching around 50 mmHg. These significant reductions in sensation ratings of gas and pain were observed in the absence of any significant effects on relaxation and only small effects on energy and drowsiness, the latter being significant on unadjusted comparison. These data suggest that the effect of pregabalin is mediated by a decrease in peripheral or spinal afferent functions. In our study, the two doses of pregabalin tested did not significantly affect sensation thresholds, colonic compliance, colonic fasting tone, or phasic MI.. A reduction in rectal pain sensation in response to distension was also reported by Houghton et al. (16) in patients with IBS. Human and rodent studies ...
Warm your bottom up with lighter sensations and build up intensity slowly. Switch between areas and intensities of sensation to give the bottom time to recover and keep things interesting.. Dont use implements on the head, face, or neck (you may want to protect the neck by covering it before play). Stick to the fleshier parts of the body: butt cheeks, fleshy part of the back (avoid protruding shoulder blades), upper arms. Avoid bony parts of the body, like the spine and joints, and avoid the tail-bone or lower back, as its possible to injure the kidneys..

A new study by researchers from the Institute of Psychiatry, Psychology & Neuroscience (IoPPN) has identified a link between impaired interoception - the ability to perceive internal sensations such as hunger, pain, disgust or fear - and alexithymia or emotional blindness.
The structure of the ear reflects that of a homunculus, which refers to a whole human body in miniature. The structures of the hands and feet also correspond to a homunculus. While walking, parts of the feet that correspond to different parts of the whole body are stimulated. When the hands touch, different parts of the whole body are also stimulated. A bodily sensation is achieved through contact with the outside world, which provides a sense of orientation through information from the distal parts of the body: feet, hands and ears. Ears also provide a sense of orientation by interacting with sounds from the outside world. The position of the ears on the side of the head means they stimulate centrally. The ears movements, together with the head, stimulate the archways and a synchronous sensation is produced for the head and body in their positioning relative to each other, which is then synchronized with the sense of the direction sounds are coming from. Together, the different forms of the ...
Enough of underwear…I felt a small ping and my heart started pounding. Now I am not psychic, I have never claimed to be, and I do not understand these things, but what happened next to this day doesnt really make sense. I had no other sensations at this point but I leapt off my chair and walked quickly to Claire (my oxygen machine) and turned her up to the maximum 5 litre flow. I then grabbed the phone, realised I was still connected to the bloody internet¸ disconnected and dialled 999. Whilst doing this I opened the front door got outside and shouted fire! (absurdly following advice from some cheesy teen magazine advising if you are being assaulted to shout fire as people are more likely to come to your aid - who says magazines dont teach us anything.) it was only at this point I really began gasping for breath. So the inexplicable part remains, how did I know what was about to happen therefore what to do? I had previously had a collapsed lung but it was a completely different experience ...
In recent years, ketamine has become the hottest thing to wear a syringe in the emergency department and the ambulance, and is starting to find its way into the ICU as well. It is a non-opioid, instead causing dissociation: it leaves the higher functions of the brain intact, yet disconnected from bodily sensations. Thus, there is little to no respiratory depression and it is extremely hemodynamically stable, usually causing not suppression but stimulation of blood pressure and heart rate (although in severe shock, as with any sedative, it can still cause decompensation).. At low doses, it is a potent analgesic, effective even in patients resistant or tolerant to opioids. Push .1-.3 mg/kg (usually 10-20 mg in adults) every 10 or 20 minutes, or better yet, infuse it in a minibag, since a fast push tends to cause more side effects.. At higher doses of ,1 mg/kg, it causes complete dissociation, essentially a state of general anesthesia with no connection between mind and body. Anything from surgery ...
Sensation and perception work seamlessly together to allow us to detect both the presence of, and changes in, the stimuli around us.. The study of sensation and perception is exceedingly important for our everyday lives because the knowledge generated by psychologists is used in so many ways to help so many people.. Each sense accomplishes the basic process of transduction - the conversion of stimuli detected by receptor cells into electrical impulses that are then transported to the brain - in different, but related, ways.. Psychophysics is the branch of psychology that studies the effects of physical stimuli on sensory perceptions. Psychophysicists study the absolute threshold of sensation as well as the difference threshold, or just noticeable difference (JND). Webers law maintains that the JND of a stimulus is a constant proportion of the original intensity of the stimulus.. Most of our cerebral cortex is devoted to seeing, and we have substantial visual skills. The eye is a specialized ...
To present realistic skin sensation for virtual reality, SmartTouch selectively stimulates each kind of receptor in the skin and reconstructs complex tactile sensations by combining these stimuli (tactile primary colors, analogous to the three primary colors for vision). This is acheived with electrical stimulation through the skin (electro-tactile display). Electrical current from surface electrodes generates an electric field inside the skin, which induces nerve activity. The basic idea is to utilize the different placement of sensory nerves and control the electric field by changing current-source distribution at the skin surface ...

The original LP was released on 23 May 1970 in stereophonic format.[1] There is an 8-second segment near the beginning of "Magic Bus" (leading into the lyric I don't care how much I pay) where the music is played backwards. Townshend stated that he did this deliberately to mark a part he had edited due to several mistakes. The 1995 and 2001 CD mixes edit this section differently and do not have the backward portion. The backwards portion was retained on Greatest Hits Live. The album was reissued on CD in 1985 by MCA in the US, and in 1987 by Polydor in Germany. In February 1995, the album was reissued as a remixed CD which included more songs than the original vinyl edition, as well as song introductions and other banter that had been edited out of the original release. For the remix, new vocal overdubs from Daltrey, Townshend and Entwistle were recorded to address occasional flaws in the original tapes or performances. The additional songs were inserted before and in the middle of the original ...
