The Posterior Cingulate Cortex forms a central node in the “default mode network” of the brain. The PCC along with the precuneus is implicated as a neural substrate for human awareness. In numerous studies on attention and awareness, the PCC has been found to be activated during self-related thinking. Distracted and controlled awareness corresponded with PCC activation.
The anterior cingulate cortex is speculated to monitor and control the attention and impulse centers of the brain. It is frontal part of the cingulate cortex which resembles a collar. It effectively keeps us motivated and on task. This is where the primary and secondary motor cortices are located. They control movement and activity. Children with ADD/ADHD often exhibit difficulty in understanding the consequences of their behavior. Research has also shown that the ACC is correlated with emotional awareness.
