Definition

The callosal sulcus, also known as the corpus callosum sulcus, is a prominent groove or furrow that separates the two cerebral hemispheres of the brain.

Anatomy

The callosal sulcus is located on the medial surface of the brain and extends horizontally. It stretches from the uppermost part of the brain to the lowermost part, dividing the cerebral hemispheres into left and right halves.

Function

The main function of the callosal sulcus is to demarcate the separation between the two cerebral hemispheres. It plays a crucial role in the connection and communication between the left and right cerebral hemispheres, which is facilitated by the corpus callosum, a large band of nerve fibers that connects the two hemispheres. The callosal sulcus serves as a landmark for identifying and studying brain structures and is important for understanding brain functions.
