Which boundary separates the frontal lobe from the parietal lobe?

Explanation:
The central sulcus is the boundary between the frontal and parietal lobes. Also called the Rolandic sulcus, it runs from near the top center of the brain down toward the lateral surface and separates the precentral gyrus (the primary motor area) in the frontal lobe from the postcentral gyrus (the primary somatosensory area) in the parietal lobe. The lateral sulcus (Sylvian fissure) separates the frontal and parietal lobes from the temporal lobe on the lateral surface, not the boundary between frontal and parietal. The longitudinal fissure divides the two cerebral hemispheres, left and right, so it isn’t a boundary between lobes within a hemisphere.
