The term area 24cv refers to the part of area 24c in the human that is located in the ventrorostral bank of the cingulate sulcus where the cingulate gyrus curves around the genu of the corpus callosum. The other part of area 24c, area 24cd, is located in the dorsorostral bank of the sulcus. The equivalent area 24c of the macaque is not subdivided ( Vogt-2012 ). The rat and mouse have no structure equivalent to area 24c ( Vogt-2013 ).
