The lateral sulcus (also called Sylvian fissure or lateral 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 lateral sulcus is one the earliest-developing sulci of the human brain. It first appears around the fourteenth gestational week.[1] Image File history File links Lateral_sulcus. ... Image File history File links Gray724. ... For other uses, see Latin (disambiguation). ... NeuroNames is a system of nomenclature for the brain and related structures. ... For other uses, see Brain (disambiguation). ... The frontal lobe is an area in the brain of mammals. ... The parietal lobe is a lobe in the brain. ... The temporal lobes are part of the cerebrum. ... The human brain as viewed from above, showing the cerebral hemispheres. ...


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 is part of the primary localized auditory cortex. Inferior frontal gyrus of the human brain. ... The transverse temporal gyri (also called Heschls gyri) are found in the area of primary auditory cortex in the superior temporal gyrus of the human brain. ... The primary auditory cortex the region of the brain which is responsible for processing of auditory (sound) information. ...


It was named the sylvian fissure after Franciscus Sylvius (1614-1672), professor of medicine at Leiden University. Franciscus Sylvius (1614-1672), also known as Franz De Le Boe, was a German physician and scientist (chemist, physiologist and anatomist) and professor of medicine at the University of Leyden. ...

The lateral surface is limited in front by the lateral part of the parietoöccipital fissure, and by a line carried from the end of this fissure to the preoccipital notch; it is traversed by the transverse occipital and the lateral occipital sulci.
The transverse occipital sulcus is continuous with the posterior end of the occipital ramus of the intraparietal sulcus, and runs across the upper part of the lobe, a short distance behind the parietoöccipital fissure.
The lateral occipital sulcus extends from behind forward, and divides the lateral surface of the occipital lobe into a superior and an inferior gyrus, which are continuous in front with the parietal and temporal lobes.

In neuroanatomy, a sulcus (pl. sulci) is a depression or fissure in the surface of the brain.
Sulcus temporalis superior (ts) - this sulcus runs parallel to the lateral fissure and extends to the temporal pole and often superficially merges with it.
parietal lobe: postcentral sulcus, postcentral gyrus (1, 2, 3, 43), superior parietal lobule (5), inferior parietal lobule (39-angular gyrus, 40), precuneus (7), intraparietal sulcus
