Definition for Parietal lobe
From Biology Forums Dictionary
The parietal lobe is a highly convergent cortical region and a major network way station. It is positioned above (superior to) the occipital lobe and behind (posterior to) 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 dorsal stream of the visual system. This enables regions of the parietal cortex to map objects perceived visually into body coordinate positions. The name derives from the overlying parietal bone, which is named from the Latin pariet-, wall.
The parietal lobe is defined by four 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 medial longitudinal fissure divides the two hemispheres.
