• receptor
  • The chemicals that are in the air around you will then diffuse across the mucus membrane and hit the cilia, stimulating the olfactory receptor neuron. (scientopia.org)
  • Each olfactory receptor neuron makes a specific kind of olfactory receptor protein (we think it's just 1:1, but we could be wrong), and we have over 1000 genes for olfactory proteins to chose from (srsly it makes up more than 1% of our genome. (scientopia.org)
  • We hypothesize that NMDA receptor (NMDAR)-mediated olfactory input to mitral cells is enhanced during training, such that increased calcium facilitates and shapes the critical cAMP pattern. (mun.ca)
  • The second revolution began in April, 1991 when Linda Buck and Richard Axel published their discovery of 1,500 olfactory receptor genes. (firstnerve.com)
  • As genes go, the olfactory receptor (OR) genes are relatively simple: think of them as different colored beads (amino acids) on a string. (firstnerve.com)
  • impulses
  • This was the long sought after mechanism by which the nose transforms chemical signals (odor molecules) into electrical ones (nerve impulses). (firstnerve.com)
  • The measurement of a temperature pulse and the claimed absence of heat release during an action potential were the basis of the proposal that nerve impulses are an adiabatic phenomenon much like sound waves. (wikipedia.org)
  • Anatomy
  • Because Latin was the lingua franca (common language) of the study of Anatomy when the nerves were first documented, recorded, and discussed, many nerves maintain Latin or Greek names, including the trochlear nerve (IV), named according to its structure, as it supplies a muscle that attaches to a pulley (Greek: trochlea). (wikipedia.org)
  • odor
  • There are olfactory testing packets in which strong odors are embedded into cards and the responses of the patient to each odor can be determined. (wikipedia.org)
  • Rat pup odor preference learning follows pairing of bulbar beta-adrenoceptor activation with olfactory input. (mun.ca)
  • Injury
  • 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. (bl.uk)
  • occur
  • Lesions to the olfactory nerve can occur because of "blunt trauma", such as coup-contra-coup damage, meningitis, and tumors of the frontal lobe of the brain. (wikipedia.org)
  • However, it is not known what olfactory disorders occur and if they are indeed a symptom of a depressive disorder. (wikipedia.org)
  • All cranial nerves are paired, which means that they occur on both the right and left sides of the body. (wikipedia.org)
  • skull
  • If the brain is carefully removed from the skull the nerves are typically visible in their numeric order, with the exception of the last, CN XII, which appears to emerge rostrally to (above) CN XI. (wikipedia.org)
  • Cranial nerves have paths within and outside the skull. (wikipedia.org)
  • There are many holes in the skull called "foramina" by which the nerves can exit the skull. (wikipedia.org)
  • typically
  • Naegleria fowleri propagates in warm, stagnant bodies of freshwater (typically during the summer months), and enters the central nervous system after insufflation of infected water by attaching itself to the olfactory nerve. (wikipedia.org)
  • Most typically, humans are considered to have twelve pairs of cranial nerves (I-XII). (wikipedia.org)
  • Origin
  • If the function is on the opposite side to the origin of the nerve, this is known as a contralateral function. (wikipedia.org)
  • results
  • An action potential traveling along a mixed nerve results in a slight increase in temperature followed by a decrease in temperature. (wikipedia.org)
