It is in both [[Cerebral hemisphere|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.<ref>{{Cite journal | author = Jee G. Chi, Elizabeth C. Dooling, Floyd H.

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]]. ==References== <div class="references-small"><references/></div> ==Additional images== <gallery> Image:Gray710.png|Coronal section through mid-brain.
