cingulate cortex

a long strip of cerebral cortex on the medial surface of each cerebral hemisphere in the prefrontal lobe. The cingulate cortex arches over and generally outlines the location of the corpus callosum, from which it is separated by the callosal sulcus. It is a component of the limbic system and has a role in emotion and memory; it also has a role in motor planning. Also called callosal gyrus; cingulate gyrus; gyrus cinguli. See also anterior cingulate cortex; posterior cingulate cortex.
