area 32ac
Acronym: 32ac
The term area 32ac refers to one of two parts of area 32 identified by Ongur-2003 in the human. It is an architectonic area identified by multiple stains in the external cingulate gyrus rostral to the genu of the corpus callosum. It is located between area 10p rostrally, area 10r ventrally, and area 9 and area 8 dorsally. Area 24a and area 24b separate it ventrocaudally from the other part of area 10, area 32pl. It is one of four subdivisions of the medial prefrontal cortex in the human; the others are area 32pl, area 25, and parts of area 24. It is the same as area 32 of Brodmann (human) ( Ongur-2003 ). For the relations of this segmentation and terminology to others, see Ongur-2003.
     Topologically it is equivalent to the pregenual part of area 32 (macaque), but architectonically it is different. In the human, only area 32pl is architectonically equivalent to area 32 (macaque). As agranular cortex it may have an equivalent in the rat; see orbital areas (rodent) ( Preuss-1995; Wallis-2012 ).
