Nelson (Ohio State U.) introduces behavioral endocrinology to upper-level undergraduate and graduate students in psychology, biology, anthropology, and zoology. He emphasizes a comparative approach and explores the endocrine mechanisms that have evolved in human and nonhuman animals to solve problems in survival and reproduction. The text is organized around the theme that hormones affect behavior by influencing one or more of three components of behavior in animals: input mechanisms such as sensory or perceptual processes, the central processing mechanisms of the nervous system, and output mechanisms like effectors and peripheral structures. This edition has new chapter summaries and a new companion website with videos, sound files, animations, and graphics. It also integrates updates on how genomics has influenced approaches used in the study of behavioral endocrinology. All chapters have been updated.
