The (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.
In the left hemisphere the lateral sulcus is between
Wernicke's Area and
Broca's Area . The
Transverse Temporal Gyrus is also nearby. As the above areas of the brain are involved in
Language function the lateral sulcus appears also involved in language. '"Cortical areas that may be implicated in impaired language functioning include the Sylvian fissure." (Leonard, 2001).
It was named the sylvian fissure after
Franciscus Sylvius (1614-1672), professor of medicine at Leiden.
