Based on cytoarchitectonics it can be divided into the Brodmann areas 23, 24, 26, 29, 30, 31 and 32. The areas 26, 29 and 30 is usually referred to as the retrospenial areas.
Cingulate cortex can also be differentiated based on its thalamic connections1: Anterior cingulate cortex receives primarily from the midlline and intralaminar nuclei and posterior cingulate cortex receives mainly from the anterior thalamic nuclei.
Anterior cingulate cortex can further be divided in the perigenual anterior cingulate cortex and midcingulate cortex.
