Cingulate sulcus

Cingulate Sulcus

The Cingulate Sulcus (pronunciation: sin-gyuh-lit sul-kus) is a prominent structure in the human brain that separates the cingulate gyrus from the superior frontal gyrus.

Etymology

The term "Cingulate" is derived from the Latin word "cingulum" which means "girdle". This is in reference to the structure's curved shape, which resembles a girdle encircling the brain. The term "sulcus" is also Latin in origin, meaning "groove" or "furrow", referring to the groove-like nature of the structure.

Anatomy

The Cingulate Sulcus begins near the rostrum of the corpus callosum, and runs upward and forward, and then curves around the genu, continues backward on the upper surface of the corpus callosum, and finally ascends to the superomedial border of the hemisphere a short distance behind the paracentral sulcus.

Function

The Cingulate Sulcus is part of the limbic system, which is involved in emotion formation and processing, learning, and memory. The sulcus also plays a role in executive functions and attention.
