The central sulcus, also known as the sulcus of Rolando, is one of the largest sulci present in the brain. It is located between the frontal and parietal lobes. Apart from being the boundary between the two lobes, it demarcates the primary motor cortex (precentral gyrus) and primary somatosensory cortex (postcentral gyrus).
The central sulcus starts near the superomedial border of the hemisphere. It then descends forwards and ends above the posterior ramus of the lateral sulcus. The entire sulcus is shaped as a lengthened letter 'S'.
The central sulcus hosts an artery and vein that are named after the sulcus, or the vein of central sulcus and artery of central sulcus.
