Supertemporal fissure refers to a specialized anatomical structure located in the human brain. More specifically, it is a deep groove or separation found on the lateral (side) surface of the cerebral cortex, contributing to the overall folding and organization of this outermost layer of the brain.
The term "supertemporal" derives from the Latin prefix "super," meaning above or beyond, and "temporal," pertaining to the temporal lobe, which is one of the four main lobes of the cerebral cortex. This suggests that the supertemporal fissure is situated superiorly or above the temporal lobe.
The fissure itself represents a natural separation or indentation, frequently observed in neuroimaging techniques such as magnetic resonance imaging (MRI) scans. It serves as a landmark or boundary that aesthetically divides the brain's lateral surface into distinct regions and gyri (convolutions).
Although the precise functional significance of the supertemporal fissure is still being explored, it is believed to play a role in advanced cognitive processes and perception, such as higher-order thinking, language processing, and sensory integration. The presence and morphology of the supertemporal fissure can vary among individuals, highlighting the uniqueness of every human brain.
In summary, the supertemporal fissure is a deep groove located above the temporal lobe on the lateral surface of the cerebral cortex. Its distinctive features contribute to brain folding and organization, potentially influencing complex cognitive functions.
