This text provides a comprehensive survey of work in visually guided prehension developmental studies of accurate grasping in human infants, and neuropsychological work on praxic control in individuals with brain damage. It examines the following topics: electrohysiological studies of motor and premotor areas in the cerebral cortex, kinematic studies of prehension in normal and neurologically-impaired individuals, and elevtomyographic studies of muscles controlling grasping. This book also makes a contribution to the fields of neuroscience, cognitive psychology, artificial intelligence, psychobiology, cognitive science, and kinesiology.
