Previous studies of the olfactory nerve, mainly in higher vertebrates, have indicated that axonal injury causes total degeneration of the mature neurons, followed by replacement of new neuronal cells arising from undifferentiated mucosal cells. A similar regeneration process was confirmed in the garfish olfactory system. Regeneration of the nerve, crushed 1.5 cm from the cell bodies, is found to produce three distinct populations of regenerating fibers. The first traverses the crush site 1 wk postoperative and progresses along the nerve at a rate of 5.8 +/- 0.3 mm/d for the leading fibers of the group. The second group of fibers traverses the crush site after 2 wk postcrush and advances at a rate of 2.1 +/- 0.1 mm/d for the leading fibers. The rate of growth of this group of fibers remains constant for 60 d but subsequently falls to 1.6 +/- 0.2 for the leading population of fibers. The leading fibers in the third group of regenerating axons traverse the crush site after 4 wk and advance at a ...
The olfactory nerve is typically considered the first cranial nerve, or simply CN I, that contains sensory nerve fibers relating to smell. The afferent nerve fibers of the olfactory receptor neurons transmit nerve impulses about odors to the central nervous system, where they are perceived by the sense of smell (olfaction). Derived from the embryonic nasal placode, the olfactory nerve is somewhat unusual among cranial nerves because it is capable of some regeneration if damaged. The olfactory nerve is sensory in nature and originates on the olfactory mucosa in the upper part of the nasal cavity.[1] From the olfactory mucosa, the nerve (actually many small nerve fascicles) travels up through the cribriform plate of the ethmoid bone to reach the surface of the brain. Here the fascicles enter the olfactory bulb and synapse there; from the bulbs (one on each side) the olfactory information is transmitted into the brain via the olfactory tract.[2] The fascicles of the olfactory nerve are not visible ...

Rods, cones and nerve layers in the retina. The front (anterior) of the eye is on the left. Light (from the left) passes through several transparent nerve layers to reach the rods and cones (far right). A chemical change in the rods and cones send a signal back to the nerves. The signal goes first to the Retina bipolar cell and Retina horizontal cell(yellow layer), then to the Retina amacrine cell and Retinal ganglion cell(purple layer), then to the optic nerve fibres. The signals are processed in these layers. First, the signals start as raw outputs of points in the rod and cone cells. Then the nerve layers identify simple shapes, such as bright points surrounded by dark points, edges, and movement. (Based on a drawing by Santiago Ramón y Cajal, 1911 ...
The most striking features of FXGs are their localization to axonal and presynaptic compartments, restriction to a subset of brain circuits during defined developmental periods, absolute dependence on FXR2P and regulation by FMRP. All of these attributes distinguish FXGs from the ubiquitous pool of Fragile X proteins investing the somatodendritic domain. Here, we will discuss the evidence supporting the assignment of FXGs as a novel context for Fragile X proteins and the implications of these findings for FXS and autism.. Several lines of evidence support the conclusion that FXGs are predominantly localized to the axonal and presynaptic compartments of selected neurons. (1) FXGs are most abundant in neuropil, e.g., strata oriens and lucidum in hippocampal area CA3 as well as the glomeruli of the olfactory bulb (Figs. 1 ⇑ ⇑-4). (2) FXGs are also observed in the axons in the hilus of the hippocampus and in the olfactory nerve layer (Fig. 3 B; supplemental Fig. S1, available at ...
Odobenocetops (/ˌoʊdəbiːˈnɒsɪtɒps/) was a small toothed whale known from Peru and Chile. Restricted to the Neogene (mostly Miocene), the genus is believed to have become extinct before the Pliocene. It had two tusks, and, in some fossils, one tusk was longer than the other. Odobenocetops can be identified as a cetacean based on several features unique to this order: The presence of large air sinuses in the auditory region connected to large pterygoid sinuses. The large supraorbital process of the frontal bone overhanging the orbital region. Narial fossae opening dorsally (thought not at the apex of the skull like in other cetaceans.) The absence of a true cribriform plate (a bony blade separating the nares). In Odobenocetops, a group of foramina in this plate allows the passage of olfactory nerves connected to the small olfactory lobes in the brain. In other cetaceans, the olfactory nerves are similarly present but strongly reduced. The elbow joint is immobile, as shown by a single ...

I feel very much rooted in the earth, but my friends and family describe my personality as "free spirited." It is good to be free spirited and wholly alive, methinks, swimming in the flow until fingers get pruney and ones soul feels saturated and content. Life is a mystery to be cherished and traveled. I like to eat good food. Soak up Natures beauty. Laugh in the company of good people. Drum at pickup music sessions. Feel lambs ear and pine and lavender and sage between my fingers. Count the stars in the sky and watch satellites whiz by in their orbits. I like listening to the old ones and absorbing their stories that always manage to sound fresh. I feel honored when the Muse sits and visits and the dreams that dance me into other realms at night. The synchronicities that lead my way each day, always making me feel like Alice. And the quiet that can be heard in the desert and on the shore and in the trees ...

Although infection occurs through direct contact with tainted waters, its not possible to catch the bacteria from another person. When tainted water is introduced into the nose through bathing or swimming, the bacteria invades and attaches to your nervous system and brain. It attaches to your olfactory nerve and moves to your olfactory bulbs-where it causes significant damage-then migrates to the brain. The disease progresses quickly and victims experience several symptoms including changes in taste and smell, headache, fever, nausea, and vomiting. It then leads to confusion, hallucination, a lack of attention, loss of balance, and seizures. It significantly shortens your life cycle as death occurs one to two weeks after the first symptoms are experienced.. ...
Cannabinoids are most beneficial when they reach our bloodstream without being passed through an organ. Therefore, when you spray vapors of CBD into your passage they are directly transported to your bloodstream in a matter of seconds. Without having to pass through the liver where all substances are transported to be absorbed into the bloodstream, CBD molecules through respiratory tract is absorbed 6-8 times more efficiently. The extensive network of vascular capillaries under the nasal skin mucosa guarantees immediate and easy conduction of active neurons to and from the brain. There are two cranial nerves, the Olfactory Nerve and the Trigeminal Nerve that acts as a direct passageway to brain. ...
The lack of visual representations is one of the difficulties in studying the psychology of odor perception. Chemists have models of molecular structure and anatomists can trace the olfactory nerves with dyes. But for smells loose in the real world, psychologists and odor trackers need a compelling visual representation. Esther Wus artistic approach is a great starting point ...
What did I get? Well, instead of the above (which could be, for some, overwhelming to the olfactory nerves and cause sensory overload), I got a very pleasant candle of cedar with just enough tobacco aroma to cut the sweetness. It is a great blend. No over-"floweriness" (or sweetness) of the plain cedar (which Johnny, the owner, sent me for comparison), so it wont smell like your grandmas house, but no overpowering tobacco smell, either. In my honest opinion, Johnny and the folks at Valor did a great job with this scent ...
solemnly declare that during the whole of my residence--nearly five years--I never saw the table otherwise than plentifully and wholesomely supplied…I confess that sometimes, at the breakfast hour, our olfactory nerves were saluted with a perceptible odour of burnt porridge; but I have known the milk to be burnt now and then at Thornycroft Hall; and certainly our bread and butter was cut in "planks," not slices, and the butter was, perhaps, a little hard to find…but if you had seen the large dishes-full replenished again and again till every girl was satisfied; if you had seen them passing down the long narrow tables in the lofty eating-room, disappearing with astonishing rapidity; if you had counted the number of "planks" each young lady consumed, you would not have imagined any pupil to be badly served. ...

Ambient particles matter and nanoparticles have been seen as a cause of changing brain activity and influencing the central nervous system. Over the past decades, several studies have suggested that nanoparticles could arrive to the brain through the inhalation of these particles via olfactory nerves. Passage to the brain is a particular concern since it has been demonstrated that nanoparticles are potent inducers of oxidative stress. The reason why the oxidative stress is so worrying is because it has been related to the appearance of several neurodegenerative diseases such as Parkinsons or Alzheimers disease. MRI evaluation of the brain reaches two results. Firstly, those children who live in more polluted locations revealed greater prefrontal lesions; and secondly, highly-exposed children and young adults showed upregulated inflammatory markers.. In particular diesel exhaust pollutants has been identified as an important and harmful source of health diseases. We can take as an example this ...
The skull, facial bones, and scalp provide protection and insulation to the deeper structures. The scalp and face are rich in blood vessels that vasodilate in response to cold to maintain normal body temperatures within these vital structures. The head contains the organs of special sense: the eyes, ears, olfactory nerve, and taste buds of the tongue. Impairment of the special senses suggests problems with the sensory organs, their CNs, or the brain. The tongue, pharynx, and larynx are the organs of speech. Changes in articulation suggest anatomic or functional problems with these structures. The nose, mouth, pharynx, larynx, and trachea form the upper airways; any compromise of these structures may impair effective respiration and effect changes in the tone or volume of voice. The mouth, teeth, mandible and maxilla, tongue, salivary glands, pharynx, and upper esophagus are the upper alimentary tract necessary for mastication and swallowing of food. The head and neck are highly vascular. The ...
Dr. Tina Ridgeway, the female neurosurgeon who is destined to hook up with the hunky neurosurgeon with nightmares (another Dr. Jekyll? See "Do No Harm"), presented a case at M&M conference. The patient, a chef, suffered olfactory nerve damage during a craniotomy for a meningioma. She acknowledged that she relied on the resident to obtain informed consent. This is not permitted in most hospitals. The chief of surgery then castigates her for allowing the resident to do the case. When I was a chief of surgery, I usually was faced with the opposite problem. Some of the attending staff were not letting the residents do enough ...
Its up to you, but be careful--lots of devils lurk in trying to approximate the contributions of a cell to extracellular field. An initially plausible but probably fatally flawed strategy would be to rely on somatic membrane current (insert extracellular into the soma, then multiply i_membrane by area of that segment). This would be easy to implement in NMODL with a statement in a BREAKPOINT block (so it would occur automatically at every time step, and be performed by compiled code). The flaw is that somatic current grossly overemphasizes the contribution of spike currents while grossly underestimating the effect of synaptic currents ...

I am interested in describing synaptic circuits in the olfactory bulb, the first relay station for odor processing in the brain. In the mammalian olfactory system, sensory inputs converge in the olfactory bulb in spatially segregated anatomical structure called glomeruli. Olfactory neurons expressing the same olfactory receptor project in specific glomeruli where they transmit sensory information to ~25 mitral and tufted cells, the principal output neurons of the bulb. Each glomerulus is surrounded by local juxtaglomerular neurons that shape the output of mitral and tufted cells. Juxtaglomerular cells include different types of neurons like inhibitory periglomerular cells, excitatory external tufted cells and mixed dopaminergic-GABAergic short axon cells.. My earlier work focused on intraglomerular excitatory interactions that amplify the complex and unique long-lasting synaptic response of mitral and tufted cells to an olfactory nerve input. I demonstrated the unexpected role of external tufted ...
Glaucoma is the term used to describe a group diseases characterised by a specific type of damage to the optic nerve head (ONH) known as cupping and a characteristic type of visual field loss. This loss is associated with progressive atrophy and loss of the retinal ganglion cells. Glaucoma is a leading cause of irreversible blindness in the world. This project was aimed at investigating olfactory ensheathing cells (OEC), a population of radial glia proven to be neuroprotective in central and peripheral nerve injury models, and their potential to protect the retinal ganglion cells in glaucoma. We studied the interactions of RGC and OEC in culture. We show that OEC can straighten, ensheath and bundle RGC neurites as well as support the survival of RGC and their synapses in culture. We also show that OEC endocytose dead RGC in culture. We modified a rat model of glaucoma (where paramagnetic microbeads are injected into the anterior chamber of the rat eyes) and characterised the early and late ...
Olfactory ensheathing cells (OECs) are the glial cells of the olfactory system. Their primary role is thought to be to provide support and guidance for primary olfactory axons. However, OECs are known to phagocytose bacteria and express immune markers and thus they may help to maintain a healthy environment. Interestingly, following widespread death of primary olfactory axons, there is minimal mobilisation of macrophages but yet the axonal debris is rapidly cleared. Purpose: We have therefore investigated whether OECs are the cells that are primarily responsible for removal of axonal debris. Methods: We cultured red fluorescent OECs from S100beta-DsRed mice and green fluorescent primary olfactory neurons from OMP-ZsGreen mice. Results: In explant cultures of DsRed-OECs and ZsGreen-neurons, OECs clearly contained green fluorescent axonal debris. When cellular debris from green fluorescent neurons was added to cultured OECs, the OECs extended pseudopodia and rapidly phagocytosed the axonal debris ...
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.[13] 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 ...

In the present study, we have shown that Robo proteins are expressed in cultured OECs and exhibit enriched distribution at the leading edge. A Slit-2 gradient indeed strongly repelled the migration of these cultured OECs. To our knowledge, this is the first guidance factor discovered to repel OEC migration. Because Slit-2 is highly expressed in the apical cells of OE, it is likely that it might help Robo-expressing OECs and olfactory axons migrate out of the OE through chemorepulsion during early development. Slits expressing in the OB might also regulate the stop and scattering of OECs that have arrived at the surface of the OB. OECs have been reported to pioneer the olfactory sensory nerves and provide a conductive substrate for the growth of olfactory sensory axons during development (Tennent and Chuah, 1996; Tisay and Key, 1999). An intriguing possibility is that the guidance of OECs by Slits might contribute to the guidance of axons because of the close interaction between neurons and glia. ...

The term olfactory bulb refers, in the human and macaque, to a small oval white structure located in the cleft between the ventral surface of the frontal lobe and the floor of the cranial cavity ( Carpenter-1983 ). In the rat and mouse it is a much larger structure in comparison to rest of the brain; there it occupies almost a quarter of the length of the cranial cavity ( Swanson-2004 ). Though classically considered a separate structure from the cerebral cortex in primates ( Nomina-1983 ), it is classified on the basis of internal structure as a component of paleocortex in all species ( Stephan-1975 ). In all species it is connected rostrally with the olfactory nerve. Caudally in primates it connects with the olfactory peduncle; in rodents it connects through the olfactory tract directly to the olfactory tubercle and olfactory areas (rodent) of the cerebral cortex ( Swanson-2004 ). It is a layered structure that contains cell bodies of the second neurons in the olfactory system. It is a key ...

As if it wasnt bad enough that particulate matter from diesel exhaust causes a range of respiratory problems including 15,000 premature deaths each year, new research shows that even short-term exposure to nanoparticles found in diesel fumes can affect brain function.. Nanoparticles can travel to the brain via the olfactory nerve, where they could cause an oxidative stress response in the region of the brain critical to information processing.. Researchers placed subjects in a room with either clean air or diesel fumes (similar to a busy street), and used a electro- encephalograph (EEG) to measure brain response. Subjects breathing the sooty air showed a stress response in the brains cortex within 30 minutes, which continued even after they left the room.. ...
