lateral cerebral sulcus

a deep cleft marking the division of the temporal from the frontal and parietal lobes of the brain. Also called fissure of Sylvius, lateral cerebral fissure.

lat·er·al ce·re·bral sul·cus

(lat'ĕr-ăl ser'ĕ-brăl sŭl'kŭs)
The deepest and most prominent of the cortical fissures, extending from the anterior perforated substance first laterally at the deep incisure between the frontal and temporal lobes, then back and slightly upward over the lateral aspect of the cerebral hemisphere, with the superior temporal gyrus as its lower bank, the insula forming its greatly expanded floor. Two short side branches, the ramus anterior and ramus ascendens, divide the inferior frontal gyrus into an orbital part, triangular part, and opercular part.
