The '''lateral sulcus''' (or '''lateral fissure''', also called '''Sylvian fissure''', after [[Franciscus Sylvius]]) is the most prominent [[sulcus (neuroanatomy)|sulcus]] of each [[cerebral hemisphere]] in the [[human brain]]. The lateral [[sulcus (neuroanatomy)|sulcus]] is a deep [[fissure (anatomy)|fissure]] in each hemisphere that separates the [[frontal lobe|frontal]] and [[parietal lobe]]s from the [[temporal lobe]]. The [[insular cortex]] lies deep within the lateral sulcus.
