Sylvian

Sylvian fissure (also known as the lateral sulcus or lateral fissure) is a deep fissure in the brain's cerebral cortex. It is one of the most prominent structures of the brain's surface and separates the frontal lobe and parietal lobe above from the temporal lobe below.

Anatomy

The Sylvian fissure begins at the base of the brain in an area called the Sylvian point, near the brainstem. It extends laterally and forward along the side of the brain, curving around the insula and ending near the limbic lobe. The fissure is divided into three parts: the anterior horizontal part, the anterior ascending part, and the posterior part.

Function

The Sylvian fissure is an important landmark in the brain, as it separates several major lobes of the brain and is near several important structures. It is also involved in several functions, including language processing and auditory processing.

Clinical significance

Abnormalities or damage to the areas around the Sylvian fissure can lead to a variety of neurological and psychological conditions, including aphasia, dyslexia, and schizophrenia. It is also a common site for the occurrence of brain aneurysms.
