anterior cingulate cortex
Acronym: ACC
The term anterior cingulate cortex refers to one of four parts of the cingulate cortex in the human and the macaque ( Vogt-2012 ). It is an area of agranular cortex defined on the basis of multiple criteria, including internal structure, connectivity, and function. The others are the midcingulate cortex, the posterior cingulate cortex, and the retrosplenial cortex.
     In the human the anterior cingulate cortex is located rostrally in the cingulate gyrus and the subcallosal area of the limbic lobe as well as adjacent parts of the frontal lobe: the superior frontopolar gyrus and the superior rostral gyrus. Its location in the macaque is similar, except that the macaque has no superior frontopolar gyrus or superior rostral gyrus.
     It has seven components, which, listed in radial order from the corpus callosum, are area 33*, area 25, area 24a, area 24b, area 24cv, area 24cd, and area 32.
     An alternate segmentation of the topological area occupied by the anterior cingulate cortex is referred to as the medial prefrontal cortex. In the human it is composed of area 24a, area 24b, area 25, area 32pl, and area 32ac ( Ongur-2003 ). In the medial prefrontal cortex (macaque) it includes area 24 (macaque), area 25 (macaque), and area 32 (macaque) ( Carmichael-1994 ).
     The equivalent in the rat and mouse may be the anterior cingulate area of the rodent ( Swanson-2004 ).
