Long awaited, the Third Edition represents a thorough revision of this widely-used atlas. It takes into account the advances in computer-assisted brain-imaging techniques that do not restrict the plane of study and the recent progress in identifying and localizing putative neurotransmitters and neuromodulators in the brain. New sections offer coronal views of the gross brain and brain stem, biochemical neuroanatomy, magnetic resonance images, and recent computerized tomographic scans. In addition, many refinements have been made in the illustrations retained from earlier editions. As before, only the highest quality photomicrographs have been included.
