Transverse Occipital Sulcus

The Transverse Occipital Sulcus (transOcS) is a horizontal sulcus in the most anterior and superior sector of the surface of the occipital lobe. It can be considered to mark the antero-superior limit of the occipital lobe. It runs from the interhemispheric fissure (1) towards the lateral aspect of the hemisphere (2). It is seen at the posterior end of the IPS (3 shows these two sulci on the gray/white surface).
