Superior parietal lobule
Encyclopedia
The superior parietal lobule is bounded in front by the upper part of the postcentral sulcus
, but is usually connected with the postcentral gyrus
above the end of the sulcus.
Behind it is the lateral part of the parietoöccipital fissure, around the end of which it is joined to the occipital lobe
by a curved gyrus
, the arcus parietoöccipitalis. Below, it is separated from the inferior parietal lobule by the horizontal portion of the intraparietal sulcus
.
The superior parietal lobule is involved with spatial orientation, and receives a great deal of visual input as well as sensory input from one's hand. It is also involved with other functions of the parietal lobe
in general.

Postcentral gyrus
The lateral postcentral gyrus is a prominent structure in the parietal lobe of the human brain and an important landmark. It is the location of primary somatosensory cortex, the main sensory receptive area for the sense of touch...

Occipital lobe
The occipital lobe is the visual processing center of the mammalian brain containing most of the anatomical region of the visual cortex. The primary visual cortex is Brodmann area 17, commonly called V1...

Gyrus
A gyrus is a ridge on the cerebral cortex. It is generally surrounded by one or more sulci .-Notable gyri:* Superior frontal gyrus, lat. gyrus frontalis superior* Middle frontal gyrus, lat. gyrus frontalis medius...

Intraparietal sulcus
The intraparietal sulcus is located on the lateral surface of the parietal lobe, and consists of an oblique and a horizontal portion. The IPS contains a series of functionally distinct subregions that have been intensively investigated using both single cell neurophysiology in primates and human...

Parietal lobe
The parietal lobe is a part of the Brain positioned above the occipital lobe and behind the frontal lobe.The parietal lobe integrates sensory information from different modalities, particularly determining spatial sense and navigation. For example, it comprises somatosensory cortex and the...
