The lateral sulcus (also called Sylvian fissure or lateral fissure) is one of the most prominent structures of the human brain.

Anatomy

It divides the frontal lobe and parietal lobe above from the temporal lobe below. It is in both hemispheres of the brain but is longer in the left hemisphere. The lateral sulcus is one the earliest-developing sulci of the human brain. It first appears around the fourteenth gestational week. [Cite journal

The lateral sulcus has a number of side branches. Two of the most prominent and most regularly found are the ascending (also called vertical) ramus and the horizontal ramus of the lateral fissure, which subdivide the inferior frontal gyrus. The lateral sulcus also contains the transverse temporal gyri, which are part of the primary auditory cortex.

Eponym

It was named the sylvian fissure after Franciscus Sylvius (1614-1672), professor of medicine at Leiden University.
