The central sulcus is a 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]].

The central sulcus joins the [[Sylvian fissure]] in only 2 % of cases (i.e., in 98% of cases there is a [[subcentral gyrus]]).

During [[neurosurgical procedure]]s, it is sometimes difficult to understand the cortical anatomy of this region.

In 68/82 hemispheres, the central sulcus did not reach the posterior ramus of the lateral sulcus. A knob on the second curve of the precentral gyrus was reliably identified in only 64/82 hemispheres

[[Focal cortical dysplasia]]s (FCDs) are mainly located in the [[frontal region]], with a particular tropism for the [[central sulcus]].
