Preferred Label : supplemental motor cortex;
Uberon definition : 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.;
