Parietal lobe
open-in-new
<p>The parietal lobe is one of the four <a href="/facts/Lobes_of_the_brain/o6LpIalC">major lobes</a> of the <a href="/facts/Cerebral_cortex/GpXosGHP">cerebral cortex</a> in the brain of mammals. The parietal lobe is positioned above the <a href="/facts/Temporal_lobe/U2wLVCrg">temporal lobe</a> and behind the <a href="/facts/Frontal_lobe/RvokInmf">frontal lobe</a> and <a href="/facts/Central_sulcus/hQPtCGq1">central sulcus</a>. </p><p>The parietal lobe integrates sensory information among various <a href="/facts/Sensory_modality/L8DqWUKH">modalities</a>, including spatial sense and navigation (<a href="/facts/Proprioception/Ik79bA2x">proprioception</a>), the main sensory receptive area for the sense of touch in the <a href="/facts/Somatosensory_cortex/0nhRsBnt">somatosensory cortex</a> which is just posterior to the central sulcus in the <a href="/facts/Postcentral_gyrus/wqs48Gtj">postcentral gyrus</a>, and the <a href="/facts/Two-streams_hypothesis/rrlVjuLm">dorsal stream</a> of the visual system. The major sensory inputs from the skin (<a href="/facts/Mechanoreceptor/rj6j4Nt3">touch</a>, <a href="/facts/Thermoreceptor/sH49VAy0">temperature</a>, and <a href="/facts/Nociceptor/f3UsD9gm">pain</a> receptors), relay through the <a href="/facts/Thalamus/UHDtUStc">thalamus</a> to the parietal lobe. </p><p>Several areas of the parietal lobe are important in <a href="/facts/Language_processing_in_the_brain/sjVw9Ppd">language processing</a>. The somatosensory cortex can be illustrated as a distorted figure – the <a href="/facts/Cortical_homunculus/5dV3njP5">cortical homunculus</a> (Latin: "little man") in which the body parts are rendered according to how much of the somatosensory cortex is devoted to them. The <a href="/facts/Superior_parietal_lobule/QTYJKLu1">superior parietal lobule</a> and <a href="/facts/Inferior_parietal_lobule/knfcBFj6">inferior parietal lobule</a> are the primary areas of body or spatial awareness. A lesion commonly in the right superior or inferior parietal lobule leads to <a href="/facts/Hemispatial_neglect/N3HrSgp4">hemispatial neglect</a>. </p><p>The name comes from the <a href="/facts/Parietal_bone/DqICftoA">parietal bone</a>, which is named from the Latin <i>paries-,</i> meaning "wall". </p>
