Anterior cingulate cortex
It appears to play a role in a wide variety of autonomic functions, such as regulating blood pressure and heart rate.
Motor cortex
Based on the pattern of projections to the spinal cord, it has been suggested that another set of motor areas may lie next to the supplementary motor area, on the medial (or midline) wall of the hemisphere. These medial areas are termed the cingulate motor areas. Their functions are not yet understood.
