Paracentral Sulcus

The Para-Central Sulcus (paraCS) forms the anterior limit of the paracentral lobule. It is a small vertical sulcus on the medial surface of the hemisphere. It runs from the posterior sector of the CingS (1), straight up to the edge of the mesial surface of the hemisphere (2). It can also come in the opposite direction, from the edge of the mesial surface down towards the cingulate sulcus (CingS) (3,4). The superior end is at the level of, or just anterior to, the superior end of the precentral sulcus. Regardless of considering it running infero-superiorly or supero-inferiorly it should always be traced starting at the lower end and moving superiorly.
