Central sulcus

The central sulcus is a sulcus, or fold, in the cerebral cortex in the brains of vertebrates. Also called the central fissure, it was originally called the fissure of Rolando or the Rolandic fissure, after Luigi Rolando. It is sometimes confused with the medial longitudinal fissure.Position of central sulcus (shown in red).Drawing to illustrate the relations of the brain to the skull. Central sulcus separates the parietal lobe (yellow) and the frontal lobe (blue).Lateral surface of left cerebral hemisphere. Central sulcus is numbered as '6'.Medial surface of right cerebral hemisphere. Central sulcus labeled on top center, in red.Human brain dissection video. Demonstrating position of the central sulcus of the left cerebral hemisphere The central sulcus is a sulcus, or fold, in the cerebral cortex in the brains of vertebrates. Also called the central fissure, it was originally called the fissure of Rolando or the Rolandic fissure, after Luigi Rolando. It is sometimes confused with the medial longitudinal fissure. The central sulcus is a prominent landmark of the brain, separating the parietal lobe from the frontal lobe and the primary motor cortex from the primary somatosensory cortex.
