Anterior cingulate cortex
The anterior cingulate cortex (ACC) is the frontal part of the cingulate cortex that resembles a ""collar"" surrounding the frontal part of the corpus callosum. It consists of Brodmann areas 24, 32, and 33.It appears to play a role in a wide variety of autonomic functions, such as regulating blood pressure and heart rate.It is also involved in rational cognitive functions, such as reward anticipation, decision-making, empathy, impulse control, and emotion.
