Behavioral neurophysiology: insights into seeing and grasping

SP Wise and R Desimone

Laboratory of Neurophysiology, National Institute of Mental Health, Poolesville, MD 20837.

One marvels at a batter's ability to hit a baseball traveling at 150 kilometers per hour or a monkey's skill in snatching a flying insect. Indeed, the ability of many animals to reach out, grasp, and manipulate objects is a feat of biological engineering unmatched by even state-of-the-art robots. But how are the objects of our attention chosen and how are the eyes and hands directed to it? Recent progress in behavioral neurophysiology has clarified some of the brain mechanisms at work.
