Sigma Receptors

This is the 12th in the Neuroscience Perspectives Series. The existence of sigma receptors in the central nervous system has only relatively recently been established. In line with the aims of Neuroscience Perspectives, this volume will cover the historical background of the subject, together with the physiological, molecular biological and pharmacological aspects, with a discussion on the concept of sigma receptors subtypes and their postulated relevance for CNS disorders.
