The Neuropsychology of Anxiety first appeared in 1982 as the first volume in the Oxford Psychology Series, and it quickly established itself as a classic work in the psychology and neuroscience literature. It presented an innovative, and at times controversial, theory of anxiety and the brain systems, especially the septo-hippocampal system, that subserve it.This completely updated and revised third edition provides a further updated theory of septo hippocampal function combined with an improved understanding of anxiety. The book includes a new chapter on prefrontal cortex integrating frontal and hippocampal views of anxiety, as well as an extensively modified chapter on personality providing a new basis for further developments of Reinforcement Sensitivity Theory. In addition, numerous figures have been fully updated and converted to colour to support the text. This book is essential for postgraduate students and researchers in experimental psychology and neuroscience, as well as for all clinical psychologists and psychiatrists.
