The septal area of the brain is part of the limbic system (that part of the brain concerned with emotion) and has a role in a number of important processes such as memory, cognition, and movement. It shares some similarity with the hippocampus, yet it remains a distinct area with unique properties. This book reviews our understanding of this area and shows how it fits into the general picture of those areas of the brain concerned with modulating mammalian behavior. The chapters, written by leading figures in behavioral neuroscience, review the anatomy, neurochemistry, physiology, and behavioral relations in the septal area. There has not been a review of the septal area in book form since DeFrance's The Septal Nuclei published by Plenum 1976, and coupled with the great deal of current research shown in the related areas of hippocampus and the amygdala, this book will be of great interest to all who research the hippocampus and the amygdala in addition to the septum itself.
