The term cingulate/retrosplenial cortex refers to a transition zone between the cingulate cortex and the retrosplenial cortical areas on the medial surface of the cerebral hemisphere of the mouse. The cingulate cortex consists of the dorsal part of the anterior cingulate area and the ventral part of the anterior cingulate area; the retrosplenial cortex consists of retrosplenial agranular cortex and retrosplenial granular cortex ( Paxinos-2001 ).
