The term area 24c of Carmichael refers to a portion of the limbic lobe and medial aspect of the frontal lobe that is defined on the basis of internal structure in the macaque. Located largely in the banks of the cingulate sulcus it is one of three components of area 24 of Carmichael in the medial prefrontal cortex (macaque). The other components are area 24a of Carmichael and area 24b of Carmichael. A feature that distinguishes area 24c from adjacent areas is the presence of many neurons stained for neurofilament protein by SMI-32 ( Carmichael-1994 ). 'area 24c of Carmichael' represents an alternate segmentation of anterior cingulate cortex, namely, medial prefrontal cortex of Carmichael. Based on a different panel of staining criteria, it differs somewhat from area 24c, which is defined as a component of anterior cingulate cortex ( Vogt-2012 ).
