Anterior cingulate cortex
It appears to play a role in a wide variety of autonomic functions, such as regulating blood pressure and heart rate.
Neural basis of self
Two areas of the brain that are important in retrieving self-knowledge are the medial prefrontal cortex and the medial posterior parietal cortex.
The posterior cingulate cortex, the anterior cingulate cortex, and medial prefrontal cortex are thought to combine to provide humans with the ability to self-reflect. The insular cortex is also thought to be involved in the process of self-reference.
