The term caudal anterior cingulate cortex refers to the posterior part of the topologically defined anterior cingulate gyrus. Defined on the basis of fMRI as functionally different from the rostral anterior cingulate cortex it corresponds approximately to the architectonically defined anterior midcingulate cortex. The rostral anterior cingulate cortex corresponds to the architectonically defined anterior cingulate cortex ( Vogt-2012 ).
