The posterior cingulate cortex (PCC) is the caudal part of the cingulate cortex, located posterior to the anterior cingulate cortex. This is the upper part of the "limbic lobe". ... Surrounding areas include the retrosplenial cortex and the precuneus.

What is the purpose of posterior cingulate cortex?

The function of the posterior cingulate cortex (PCC) is uncertain. It is a central node of the default mode network (DMN), a set of brain regions showing strongly correlated neural activity and a reliable deactivation in activity during many cognitive tasks (Raichle et al., 2001).

What is the function of the precuneus?

The precuneus is a brain region involved in a variety of complex functions,60 which include recollection and memory, integration of information (gestalt) relating to perception of the environment, cue reactivity, mental imagery strategies, episodic memory retrieval, and affective responses to pain.
