Latin sulcus parietooccipitalis, fissura parietooccipitalis NeuroLex ID Parieto-occipital sulcus | ||
Only a small part of the parieto-occipital sulcus, or parietooccipital fissure is seen on the lateral surface of the hemisphere, its chief part being on the medial surface.
The lateral part of the parieto-occipital sulcus (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 parieto-occipital sulcus (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. The parieto-occipital sulcus marks the boundary between the cuneus and precuneus, and also between the parietal and occipital lobes.
Function
The parieto-occipiatal lobe has been found in various neuroimaging studies, including PET (positron-emission-tomography) studies, and SPECT (single-photon emission computed tomography) studies, to be involved along with the dorsolateral prefrontal cortex during planning.
