The anterior cingulate cortex (ACC) is the frontal part of the cingulate cortex, that resembles a "collar" form around the corpus callosum, the fibrous bundle that relays neuron|neural signals between the right and left cerebral hemispheres of the brain. 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, as well as rational cognitive functions, such as reward anticipation, decision making, empathy[1] and emotion.[2][3]
