First published in 1987. Advances in Behavioral Pharmacology has broadened its scope in an attempt to provide a better understanding of behavioral actions of drugs and their applied implications. Each volume will be increasingly thematic and successive volumes will cover a wider range of issues. Some publications in this series, such as the present volume 6, Neurobehavioral Pharmacology, will primarily explore relations between neurochemistry and related areas of neurobiology and behavioral pharmacology.
