Written in a friendly and engaging manner, Pinel's Biopsychology introduces the fundamentals of modern biopsychology. The fourth edition has been thoroughly updated to keep Biopsychology abreast of the many recent developments in this rapidly changing field. Despite the significant infusion of new material, Pinel's text continues the tradition that has made it such a success: clear, engaging prose; an unwavering emphasis on behavior; an attractive, superbly designed and integrated illustration package; and insight-provoking accounts of modern biopsychological research.The following four features aid students in remembering the material: bold-faced key terms with marginal definitions, study exercises within chapters, "Food-for-Thought" discussion questions at the end of chapters, and helpful reference appendices. The true-life case of "Professor P" that opens Chapter 6 is a unique feature that introduces the subject of brain damage. Students will be fascinated to follow the case of "Professor P" as he recognizes the first symptoms of his brain damage and correctly predicts the location of his own brain tumor. The lessons taught by this case study will inspire greater and greater interest as it gradually becomes apparent that "Professor P" is the author himself, John Pinel.
