Both main sections—olfaction and gustation—are thricely subdivided into the topics of anatomy and neurobiology; functional measurement, ontogeny, and genetics; and clinical applications and perspectives. The last and much shorter section on other chemosensory systems is all-of-a-piece. The new edition contains an author index and 10 new chapters to account for growth in such fields as neuroscience, functional imaging, cybernetics, toxicology, structure-activity assessment, molecular biology, and animal behavior. The Handbook is meant to appeal to a wide range of medical specialists and basic scientists in academia, industry, and government, and can serve as a textbook for graduate, medical, and postdoctoral fellows from an array of disciplines. Most contributors are from the US. Annotation (c)2003 Book News, Inc., Portland, OR
