Only a small part of the Parietooccipital Fissure ( parieto-occipital sulcus or Parietoöccipital fissure) is seen on the lateral surface of the hemisphere, its chief part being on the medial surface.

The lateral part of the parietooccipital fissure (Fig. 726) is situated about 5 centimeters (cm) in front of the occipital pole of the hemisphere, and measures about 1.25 cm. in length.

The medial part of the parietooccipital fissure (Fig. 727) runs downward and forward as a deep cleft on the medial surface of the hemisphere, and joins the calcarine fissure below and behind the posterior end of the corpus callosum. In most cases it contains a submerged gyrus. It marks the boundary between the cuneus and precuneus, and also between the parietal and occipital lobes.
