Parietal lobe - Definition


Located above the temporal and occipital lobes, just behind the frontal lobe, the parietal lobe is separated from the rest of the brain by the central, lateral, and parieto-occipital sulci, or fissures. The parietal lobe contains the centers treating nerve impulses relating to touch. This is where all information about temperature, size, texture, shape, and weight are analyzed. A lesion in this lobe can lead to hemineglect, or unilateral spatial neglect, defined as an inability to "detect, find one's way towards, or respond to stimuli that carry messages when they are present in the contralateral hemispace", meaning the opposite side of the body from the side of the lobe that is damaged.
