Supplemental motor cortex
From BugSigDB
The supplementary motor area (SMA) is a part of the sensorimotor cerebral cortex (perirolandic, i.e. on each side of the Rolando or central sulcus). It was included, on purely cytoarchitectonic arguments, in area 6 of Brodmann and the Vogts. It is located on the medial face of the hemisphere, just in front of primary motor cortex. This is an element that appeared late in evolution, in monkeys, linked to the appearance of a true medial pallidum.
