FUNCTIONAL ORGANIZATION OF THE MEDIAL ASPECT OF THE PRIMATE CORTEX

Abstract

Physiological neuronography of the medial side of the hemisphere of 3 macaques and 4 chimpanzees revealed an anterior suppressor area (24s), a small retrosplenial local firer (29), a large posterior limbic area (23) which fires into areas 18 and 19, and a long antero-posterior cingular belt (areas 32 and 31) into which all suppressor areas fire. In addition, in the chimpanzee areas 10, 11 and 12 were identified on the medial side of the frontal lobe.
