text: The<unk>  (also called Sylvian fissure or<unk>  fissure) is one of the most prominent structures of the human brain.  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<unk>  is one the earliest-developing sulci of the human brain. It first appears around the fourteenth gestational week.
  The<unk>  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<unk>  fissure, which subdivide the inferior frontal gyrus. The<unk>  also contains the transverse temporal gyri, which is part of the primary localized auditory cortex.
  It was named the sylvian fissure after Franciscus Sylvius (1614-1672), professor of medicine at Leiden.
