  • 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 certain higher-level functions, such as reward anticipation, decision-making, impulse control, and emotion.

  • This corresponds to areas 24, 32 and 33 of Brodmann and LA of Constantin von Economo and Bailey and von Bonin.

    It is continued anteriorly by the subgenual area (area 25, located below the genu of the corpus callosum).

    It is cytoarchitectonically agranular. It has a gyral and a sulcal part.

     Anterior cingulate cortex can further be divided in the perigenual anterior cingulate cortex (near the genu) and midcingulate cortex. The anterior cingulate cortex receives primarily its afferent axons from the intralaminar and midline thalamic nuclei (see thalamus).

    The nucleus anterior receives mamillo-thalamic afferences. The mamillary neurons receive axons from the subiculum.

    The whole forms a neuronal circuit in the limbic system known as the Papez circuit.

    The anterior cingulate cortex sends axons to the anterior nucleus and through the cingulum to other Broca's limbic areas. The ACC is involved in error and conflict detection processes.
