| parietal lobe of cerebrum | The middle portion of each cerebral hemisphere, separated from the frontal lobe by the central sulcus, from the temporal lobe by the lateral sulcus in front and an imaginary line projected posteriorly, and from the occipital lobe only partially by the parieto-occipital sulcus on its medial aspect. Synonym: lobus parietalis cerebri, parietal lobe. (05 Mar 2000) |
