POSTSYLVIAN Meaning and
Definition
-
The term "postsylvian" is an adjective used in neuroscience and anatomy to describe an area of the brain located posteriorly (towards the back) to the Sylvian fissure. The Sylvian fissure, also known as the lateral sulcus, is one of the most prominent grooves on the lateral surface of the brain. It separates the frontal and parietal lobes from the temporal lobe.
The postsylvian region of the brain is considered significant due to its involvement in various cognitive functions, including language processing, sensory integration, and auditory perception. This area encompasses several interconnected structures, such as the posterior part of the superior temporal gyrus, the planum temporale, the parietal operculum, and parts of the insula.
Research has shown that damage or disruption to the postsylvian area can result in various neurological conditions. For example, lesions or abnormalities in this region can lead to language impairment such as aphasia or dyslexia. Additionally, deficits in sensory perception, such as auditory processing disorders, can also arise from dysfunction in the postsylvian area.
Understanding the organization and function of the postsylvian region is crucial for researchers and clinicians in neurology and neuroscience. Studying this area contributes to furthering our knowledge of brain structure and function, which can aid in diagnosing and treating disorders related to language, perception, and cognition.

Etymology of POSTSYLVIAN
The word "postsylvian" is mainly used in the field of neuroanatomy and refers to the region located behind the sylvian fissure in the brain.
Etymologically, it consists of two parts:
1. "Post": This prefix derives from Latin "post", meaning "after" or "behind".
2. "Sylvian": This term refers to the sylvian fissure, a prominent landmark in the brain named after the Belgian anatomist François Sylvius (1614–1672). The sylvian fissure is also known as the lateral sulcus, as it extends laterally along the lateral surface of the brain.
When combined, "postsylvian" literally signifies "behind the sylvian fissure" or "occurring or relating to the region situated after the sylvian fissure".
