agnosia
Yes, olfactory receptors synapse with mitral cells in the olfactory bulb. When odor molecules bind to olfactory receptors in the nasal epithelium, they activate sensory neurons that send signals to the olfactory bulb. In the olfactory bulb, these sensory neurons synapse with mitral cells, which then relay the olfactory information to higher brain regions for processing. This synaptic connection is crucial for the perception of smell.
An olfactory stimulus travels from the nasal cavity to the olfactory epithelium, where odor molecules bind to olfactory receptors. The activated receptors send signals through the olfactory bulb, which then relays the information to various brain regions, including the olfactory cortex and the limbic system. This pathway allows for the perception of smell and its emotional or memory associations.
Yes, damaged olfactory neurons can be replaced. The olfactory system has a remarkable ability to regenerate; olfactory sensory neurons are continuously renewed from basal stem cells located in the olfactory epithelium. This regeneration process allows the olfactory system to recover from injury or damage, although it may not always restore complete function.
A smell impulse begins in olfactory receptor cells located in the olfactory epithelium in the nasal cavity. These receptor cells detect specific odorants and send signals to the brain via the olfactory nerve.
There are three major types of agnosia: visual agnosia, auditory agnosia, and tactile agnosia.
inability to recognize the import of sensory impressions; the varieties correspond with several senses and are distinguished as auditory (acoustic), gustatory, olfactory, tactile, and visual.
An agnosia is an inability to recognize objects by use of the senses.
Agnosia - inability to recognize the import of sensory impressions
Lissauer was the first scientist to provide a detailed account of agnosia (1888). He hypothesized that disorders in visual object recognition could be classified as either apperceptive agnosia or associative agnosia.

Carbon monoxide poisoning is a frequent cause of apperceptive visual agnosia. The ensuing brain damage is frequently profuse and located in the posterior region of the brain.
The Olfactory nerve. CN1 Cranial Nerve I, or the first cranial nerve called the Olfactory nerve.
Axons from the olfactory nerve project to the olfactory bulb in the brain. The olfactory bulb processes and relays information about smells to other areas of the brain, such as the olfactory cortex, where scent perception occurs.
