Location of the motor areas in the brain of a chimpanzee. The extent of the motor area is indicated by stippling; it lies entirely in from of the fissure of Rolando (sulcus centralis). Much of the motor area is hidden in the sulci. The regions marked eyes indicated the area whose stimulation gives conjugate movements of the eyeballs. It is doubtful however, whether these represent motor areas proper.
