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 ...
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 ...
The frontal eye fields (FEF) are a region located in the frontal cortex, more specifically in Brodmann area 8 or BA8, [1] of the primate brain. In humans, it can be more accurately said to lie in a region around the intersection of the middle frontal gyrus with the precentral gyrus , consisting of a frontal and parietal portion. [ 2 ]
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.
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
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 calcarine sulcus begins near the occipital pole in two converging rami. [1] It runs forward to a point a little below the splenium of the corpus callosum.Here, it is joined at an acute angle by the medial part of the parieto-occipital sulcus. [1]
