Anterior cingulate cortex
It appears to play a role in a wide variety of autonomic functions, such as regulating blood pressure and heart rate.
Self-referential encoding
Medial prefrontal cortex (mPFC) activation occurs during processing of self-relevant information. When self-referent judgment is more relatable and less negative, the mFPC is activated. Finding support clear cut circuits that have high levels of activation when cognitive and emotional aspects of self-reflection are present. The caudate nucleus has not been associated with self-reference before, however, Fossati and colleagues found activity while participants were retrieving self-relevant trait adjectives. The ventral anterior cingulate cortex (vACC) is also a part of the brain that becomes activated when there are signs of self-referencing and processing. The vACC is activated when self-descriptive information is negative. There is also pCC (posterior cingulate cortex) activity seen in neuroimaging studies during self-referential processing.
