Brain winding (one on the right hemisphere and one on the left) located directly behind the central furrow on the outside of the hemisphere and slightly on its inside. The bark layer of the winding receives sensations from the skin (touch, pressure, elongation, localization of a pain and temperature stimulus) and musculoskeletal system on the opposite half of the body and makes us aware of the movements we perform and which unconsciously allow us to check that the planned movements are really being performed correctly. The cortex layer of the winding forms what is known as the "primary sensory cortex" (primary sensory cortex,
primary somato-sensory cortex : SS I).
Cytoarchitecturally , the bark layer corresponds to
Brodmann areas 3, 1 and 2).
