Central sulcus of the human brain.
The central sulcus is a fold in the cerebral cortex of brains in vertebrates. Also called the central fissure, it was originally called the fissure of Rolando or the Rolandic fissure.
The central sulcus is a prominent landmark of the brain, separating the parietal lobe from the frontal lobe. The central sulcus is the site of the primary motor area in mammals, a group of cells that controls voluntary movements of the body.
