Located or occurring outside the parietal lobe or parietal bone of the brain and skull; in anatomy, referring to structures beyond these regions.
From Latin 'extra' (outside) + 'parietal' (from Latin 'parietalis', relating to walls, from 'paries' meaning wall). The parietal bone forms the wall of the skull.
Brain damage in extraparietal regions might affect your language, vision, or movement very differently than parietal damage (which affects touch and spatial awareness), which is why neurologists are obsessed with mapping which brain area does what.
