Parietal Lobe

The parietal lobe is the central portion of the cerebral cortex, situated between the frontal lobe and occipital lobe, above the temporal lobe. The central salcus separates the parietal lobe from the frontal lobe, and the parieto-occipital sulcus partially divides it from the occipital lobe.

The parietal lobe contains the posterior central gyrus, the superior parietal lobule, the inferior parietal lobule, and parieto-occipital lobule. The parietal lobe integrates sensory information from various parts of the body, as well as knowledge of numbers and their relations, and is involved in the manipulation of objects. Portions of the parietal lobe are involved with visuospatial processing. Although multisensory in nature, the posterior parietal cortex is often referred to by vision scientists as the dorsal stream of vision (as opposed to the ventral stream in the temporal lobe). This dorsal stream has been called both the 'where' stream, as in spatial vision, and the 'how' stream, as in vision for action.
