name the five lobes of the cerebral hemispheres
Each cerebral hemisphere is composed of five lobes, called the frontal, parietal, occipital, temporosphenoidal, and central, or island of Reil. The frontal lobe comprises the anterior portion of the brain, as far back as the fissure of Rolando or central sulcus, and as far toward the base as the fissure of Sylvius.
