Recent findings have demonstrated that not only certain functions but also specific structures of the brain are sexually dimorphic. This book provides a detailed survey of known morphological and functional sex differences and discusses possible causal relationships between structure and function. In addition, it discusses the various ways in which gonadal steroids may act upon the brain so as to cause the gender-linked differences. Extensive information on human studies as well as animal experiments is included. Neurobiologists and medical practitioners working in fields such as endocrinology, psychiatry and psychology will find this book an invaluable acquisition.
