olfactory nerveSmell Identification Test™Summary This chapter discusses the cranial nerve of the most primitive "special sense," smell. The olfactory nerve is a purely sensory nerve that conveys the neural impulses that the brain is able to interpret as odors. The olfactory nerve has the ...
In this case, the olfactory nerve is responsible for our sense of smell. The odor information originates in the epithelium of the nasal cavity and is transported to the brain via components of the olfactory nerve (cranial nerve 1 - CNI) and the olfactory pathway. A decreased sense of ...
Malingerers may claim inability to “smell” a noxious, volatile substance, such as ammonia, that actually stimulates the trigeminal nerve. In the other test, given a forced-choice test of four smells, the malingering individual chooses a correct response less frequently than by chance, i.e.,...
The human olfactory nerve is comprised of 6–10 million olfactory receptor cells, of which there are nearly 400 types harboring G-protein coupled odor receptors (GPCRs) on their cilia, with a given cell expressing only one type of receptor. In most cases, each receptor responds to a range ...
making them slow travellers only achieving distances of ca. 50–100km/day during the migration period20. In this study we used experimental long range displacement combined with olfactory or trigeminal nerve section to test which sensory cues are necessary for navigation during migration. Adult birds...
The team specifically targeted the olfactory nerve cells, or neurons, in fruit flies that are normally triggered by the smell of ripe fruit. 研究小组特别针对的是嗅觉神经细胞或者神经元,而果蝇的这些细胞通常会被成熟水果散发的味道激发。 It's olfactory lobe is also 4 times that of a human. 狗...

In some animal models, SARS-CoV-2 is able to invade the brain through the olfactory nerve. The virus infects sustentacular cells and olfactory sensory neurons in the mucosa, then travels through olfactory axons, reaching the olfactory bulb of the brain. Immune cells migrate to both the mucosa...
