In the present study, an investigation has been made of the visuomotor control exerted by one half of the brain over each of the two upper extremities in the rhesus monkey. The hypothesis that one half of the brain can steer movements of each of the two extremities relatively independent from the other half has been tested and an attempt has been made to define more precisely which pathways in the centra I nervous system are i nvo I ved in this control. These studies have been done in the 'split-brain' monkey, i.e. an animal in which both halves of the forebrain have been surgically separated.
