摘要: Publisher Summary The olfactory system is important for reproductive/maternal functions, neuroendocrine regulation, emotional responses, aggression, and the recognition of conspecifics, predators, prey. Olfaction also plays a critical role in food selection, as perception flavors results from integration gustatory signals. This chapter presents neuroanatomy physiology. Odor molecules are transduced by receptor neurons (ORNs), first order located epithelium within nasal cavity. ORN axons project nerve to synaptically terminate bulb. bulb contains output neurons—mitral tufted cells—that convey information higher structures other brain systems. relay nose mitral cells strongly regulated local intrabulbar circuitry centrifugal inputs parts brain. sense smell mediated through stimulation (ORNs) volatile chemicals.
