Pathways between the nasal passages and the CSF are functional in humans, as evidenced by the fact that drugs are delivered directly to the CSF following intranasal delivery, without entering the blood to an appreciable extent 11 2014-08-21 · Olfactory adaptation is a fundamental process for the functioning of the olfactory system, but the underlying mechanisms regulating its occurrence in intact olfactory sensory neurons (OSNs) are not fully understood. In this work, we have combined stochastic computational modeling and a systematic pharmacological study of different signaling pathways to investigate their impact during short pathway in agonistic behavior, we selectively ablated all of. the aesthetasc sensilla on both lateral flagella from one. group of crayfish and compared their behavi or to that of. intact control 2008-09-01 · The olfactory receptor gene (OR) superfamily is the largest in the human genome. The superfamily contains 390 putatively functional genes and 465 pseudogenes arranged into 18 gene families and 300 subfamilies. Even members within the same subfamily are often located on different chromosomes.

The specialized olfactory receptor neurons of the olfactory nerve are located in the olfactory mucosa of the upper parts of the nasal cavity.The olfactory nerves consist of a collection of many sensory nerve fibers that extend from the olfactory epithelium to the olfactory bulb, passing through the many openings of the cribriform plate, a sieve-like structure of the ethmoid bone. The olfactory nerve (n.

The specialized olfactory receptor neurons of the olfactory nerve are located in the olfactory mucosa of the upper parts of the nasal cavity.The olfactory nerves consist of a collection of many sensory nerve fibers that extend from the olfactory epithelium to the olfactory bulb, passing through the many openings of the cribriform plate, a sieve-like structure of the ethmoid bone. The olfactory nerve (n. olfactorius) is responsible for the sense of smell and is a complete sensory nerve. The olfactory test entails individual examination of each nostril and closure of the patient’s eyes because olfactory memory leads to odor recognition. The central processing pathways of the human olfactory system are not fully understood.
