“Chemoreception and the sense of smell” is the seventh chapter of the book Sensory Transduction and begins with a general description of chemoreception, including chemotaxis in bacteria. It then describes olfaction in insects, including new discoveries of the nature of insect receptor proteins and the coding of olfaction in insects. It proceeds to review olfaction in vertebrates, beginning with the primary olfactory epithelium. It describes olfactory receptor proteins, the mechanism of olfactory transduction, and pathways of desensitization and adaptation. The basis of coding in the principal olfactory epithelium is described together with the anatomy and physiology of the olfactory bulb. A final section is provided on the accessory olfactory system and vomeronasal organ, including a description of receptor proteins, transduction cascades, and wiring to the accessory olfactory bulbs.
