The scientific study of mental disorder is exciting today because of new discoveries in molecular genetics, cognitive processes, neurochemistry and neuroanatomy. Psychopathology combines these fields of research to present a comprehensive picture of psychosis. In this important volume, distinguished investigators from these fields present new findings from their laboratories, as well as perspectives on areas of rapid growth and change. The editors also provide thoughtful overviews of four major topics in psychopathology research: brain mechanisms, thinking, development and genetics.
