Central sulcus

(anatomy) A groove situated about the middle of the lateral surface of the cerebral hemisphere, separating the frontal from the parietal lobe.

A double S-shaped fissure that extends obliquely upward and backward on the lateral surface of each cerebral hemisphere of the brain and located at the boundary between the frontal and parietal lobes. Also called central sulcus.

The noun has one meaning:

Meaning #1: a fissure extending upward on the lateral surface of both hemispheres; separates the frontal and parietal lobes
  Synonyms: Rolando's fissure, central sulcus, sulcus centralis

Brain: Central sulcus
Central sulcus of the human brain.
Lateral surface of left cerebral hemisphere, viewed from the side.
Latin	sulcus centralis cerebri
Gray's	subject #189 819
NeuroNames	hier-29
NeuroLex ID	birnlex_4035

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, after Luigi Rolando.

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.
