The term area 32 (macaque) refers to part of an alternate segmentation of the anterior cingulate gyrus in the macaque. It is defined on the basis of internal structure in the macaque. It is one of three components of the medial prefrontal cortex (macaque) in the orbitomedial prefrontal cortex (macaque). The other components are area 24 of Carmichael and area 25 (macaque) ( Carmichael-1994 ). It is topologically equivalent to area 32ac in the human, but histologically equivalent to area 32pl ( Ongur-2003 ).
