The supplementary motor area (SMA) is a part of the primate cerebral cortex that contributes to the control of movement.It is located on the midline surface of the hemisphere just in front of (anterior to) the primary motor cortex leg representation.In monkeys the SMA contains a rough map of the body.In humans the body map is not apparent.he role of the SMA was further substantiated by Cunnington et al. 2003, showing that SMA proper and pre-SMA are active prior to volitional movement or action, as well as the cingulate motor area (CMA) = anterior mid-cingulate cortex (aMCC).
