central sulcus - BrainInfo

central sulcus (cns)

The term central sulcus (cns) refers to a cleft in the lateral aspect of the cerebral hemisphere that separates the precentral gyrus (PRG) of the frontal lobe (FLB) from the postcentral gyrus (POG) of the parietal lobe (PLB). Identified by dissection, it is found in the human ( Carpenter-1983 ) and the macaque ( Martin-2000 ). Equivalent structures are not found in the smooth cerebral cortex of the rat or mouse ( NeuroNames ). Updated 22 Aug 2024.

Also known as: Sulcus centralis, central sulcus, Sulcus centralis cerebri, central sulcus of Rolando, central fissure, Rolandic fissure, fissure of Rolando, sulcus centralis (Rolandi)

Models Where It Appears

Structural CNS Model - Macaque

Brain structures of the macaque are illustrated in BrainInfo’s NeuroMaps macaque brain atlas. Structures are grouped by proximity in a hierarchy corresponding to the central nervous system hierarchy of NeuroNames ( Bowden-1995 Martin-2000 ). Structures in the NeuroMaps atlas are based on the segmentation of an MRI of the brain of a 3-year old male rhesus macaque (Macaca mulatta). The atlas is most useful for targeting structures for implantating electrodes and chemtrodes. Updated 29 Oct 2025.
