Parieto-occipital sulcus
The parieto-occipital sulcus is a deep fissure in the cerebral cortex that marks the boundary between the cuneus and precuneus, and also between the parietal and occipital lobes. Only a small part can be seen on the lateral surface of the hemisphere, its chief part being on the medial surface.
The lateral part of the parieto-occipital sulcus is situated about 5 centimeters in front of the occipital pole of the hemisphere, and measures about 1.25 cm. in length.
The medial part of the parieto-occipital sulcus 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.Function
The parieto-occipital lobe has been found in various neuroimaging studies, including PET studies, and SPECT studies, to be involved along with the dorsolateral prefrontal cortex during planning.Gallery
