The lateral part of the parieto-occipital sulcus (Fig. 726) is situated about 5 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 ...
No connections exist with premotor, motor, or somatosensory areas. The areas with which it links are involved in executive functions, working memory and motor planning. Visual Posterior Region. This occurs along the parieto-occipital fissure ( yellow in figure). This connects with visual areas in the cuneus and primary visual cortex
Animation. Parietal lobe (red) of left cerebral hemisphere. The parietal lobe is defined by three anatomical boundaries: The central sulcus separates the parietal lobe from the frontal lobe; the parieto-occipital sulcus separates the parietal and occipital lobes; the lateral sulcus (sylvian fissure) is the most lateral boundary, separating it from the temporal lobe; and the longitudinal ...
V6 is located in the dorsal part of the extrastriate cortex, near the deep groove through the centre of the brain (medial longitudinal fissure), and typically also includes portions of the medial cortex, such as the parieto-occipital sulcus (POS). [72]: 7970 DM contains a topographically organized representation of the entire field of vision.
Hippocampal fissure (h) Sulcus intraparitalis (ip) Lateral fissure (or Sylvian fissure) (la) Sulcus olfactorius (olf) Medial parieto-occipital fissure (pom) Fissura rhinalis (rh) Sulcus temporalis superior (ts) – This sulcus runs parallel to the lateral fissure and extends to the temporal pole and often superficially merges with it.
The cuneus (from Latin 'wedge'; pl.: cunei) is a smaller lobe in the occipital lobe of the brain. The cuneus is bounded anteriorly by the parieto-occipital sulcus and inferiorly by the calcarine sulcus.
The transverse occipital sulcus is a sulcus in the occipital lobe. The transverse occipital sulcus is continuous with the posterior end of the occipital ramus of the intraparietal sulcus , and runs across the upper part of the lobe, a short distance behind the parietooccipital fissure .
Behind it is the lateral part of the parieto-occipital sulcus, around the end of which it is joined to the occipital lobe by a curved gyrus, the arcus parietooccipitalis. Below, it is separated from the inferior parietal lobule by the horizontal portion of the intraparietal sulcus .
