Principles of Behavioral Genetics presents a comprehensive overview of the relationship between genes, brain and behavior. Introductory chapters provide clear explanations of basic processes of the nervous system and fundamental principles of genetics of complex traits without excessive statistical jargon. Individual chapters describe the genetics of social interactions, olfaction and taste, memory and learning, circadian behavior, locomotion, sleep, and addiction, as well as the evolution of behavior. Whereas the focus is on genetics, neurobiological and ecological aspects are also included to provide intellectual breadth. The book uses examples that span the gamut from classical model organisms to non-model systems and human biology, and include both laboratory and field studies. Samples of historical information accentuate the text to provide the reader with an appreciation of the history of the field. All chapters contain general overviews, concise summaries, study questions that promote not only memorization but also contemplation of the material, and recommendations for further in-depth reading. An extensive glossary that defines the terminology used in the book is included. This textbook encompasses a broad definition of the emerging science of behavioral genetics.
