This book presents the anatomical systems that take part in the scientific and clinical study of emotional functions and neuropsychiatric disorders. It discusses the limbic system (the cortical and subcortical structures in the human brain involved in emotion, motivation, and emotional association with memory) at length and how this is no longer a useful guide to the study of psychiatric disorders. The book provides an understanding of brain anatomy, with an emphasis on the new anatomical framework which has emerged during the last quarter century. The goal is to provide the reader will develop an understanding of the gross anatomical organisation of the human forebrain.
