Notes

The posterior cingulate cortex (PCC) is a part of the cingulate cortex, located in the medial aspect of the cerebral cortex. It is situated behind the anterior cingulate cortex and is a component of the limbic system.

Function

The posterior cingulate cortex is involved in various functions, including emotion processing, memory retrieval, and attention. It is a key part of the default mode network, which is active when the brain is at rest and not focused on the outside world.

Clinical significance

The PCC has been implicated in several neurological and psychiatric disorders. Abnormal activity in the posterior cingulate cortex has been observed in conditions such as Alzheimer's disease, schizophrenia, and depression.

Anatomy

The posterior cingulate cortex is supplied by the posterior cerebral artery. It is located adjacent to the precuneus and is part of the parietal lobe.

Research

Recent studies have shown that the PCC plays a role in self-referential thought and consciousness. It is also involved in spatial orientation and navigation.
