This large single volume dictionary defines and explains the great number of technical terms employed within those areas of neuropsychology and medicine that are strictly relevant to neuropsychology. While it does not cover wider areas such as pharmacology, psychiatry and neuropsychology, it includes all topics of direct interest to practicing neuropsychologists or those engaged on neuropsychological research with humans. Central to the book are a number of extended entries of over 8000 words which define and discuss key topics in the field. These are supported by a network of shorter entries ranging from 500 to 5000 words in length, and by a large number of glossary items which have been fully cross-referenced into the main entries.The texts have been written around a standard set of brain diagrams which enable writers on different subjects to illustrate their entries with consistent visual resources. The editors have concentrated on producing a comprehensive reference book which will be use to undergraduates, clinical workers and researchers, postgraduates in clinical psychology, speech therapists, neurologists, neurosurgeons, and psychiatrists.
