"Sensory Processes": Smell, Vision, Taste, Hearing and Touch Receptors and information processing

Brief Reviews on all the sensory processes, a good read!. It is not extensive but for college students and graduate level neuroscience and neurophysiology studies, a good reading material.

The Nose and Nasal Cavity

Olfactory sensitivity is directly proportional to spatial area in the nose—specifically the olfactory epithelium, which is where odorant reception occurs. The area in the nasal cavity near the septum is reserved for the olfactory mucous membrane, where olfactory receptor cells are located. This area is a dime-sized region called the olfactory mucosa. In humans, there are about 10 million olfactory cells, each of which has 350 different receptor types composing the mucous membrane. Each of the 350 receptor types is characteristic of only one odorant type. Each functions using cilia, small hair-like projections that contain olfactory receptor proteins. These proteins carry out the transduction of odorants into electrical signals for neural processing.
