Used for gestures of communication, environmental exploration, and the grasping and manipulating of objects, the hand has a vital role in our lives. The hand's anatomical structure and neural control are among the most complex and detailed of human motor systems.Hand and Brain is a comprehensive overview of the hand's sensorimotor control. It discusses mediating variables in perception and prehension, the coordination of muscles with the central nervous system, the nature of movement control and hand positioning, hand-arm coordination in reaching and grasping, and the sensory functi
