Schizophrenia is being increasingly viewed as a neurological disorder. This book addresses the key questions in modern schizophrenia research. How do abnormalities of the brain produce the characteristic signs and symptoms of this most severe and mysterious malady? Where are these abnormalities? How do they develop? How can we detect them? What clinical and cognitive effects do they have?; This book tackles these questions in a systematic way from a number of allied perspectives, from phenomenology to physiology, from animal behaviour to metacognition, and from PET scans to paper and pencil tests. Each chapter contains a concise review of the particular topic, empirical data and a theoretical overview.
