By means of a prominent groove, called the longitudinal fissure, the brain is dividid into two halves called hemispheres. At the base of this fissure lies a thick bundle of nerve fibers, called the corpus callosum, which provides a communication link between the hemispheres.
Each hemisphere has three poles. The frontal pole is the most anterior extent of the frontal lobe. The occipital pole is the most posterior extent of the occipital lobe. The temporal pole is the most anterior extent of the temporal lobe. The left and right cerebral hemispheres are separated by the longitudinal cerebral fissure. There are four key sulci (singular = sulcus: groove) in the cerebral hemispheres that divide the cerebral cortex into five (5) lobes. The central sulcus (sulcus of Rolando) is located just behind the most anterior vertical gyrus (plural gyri: convolution) on the lateral surface of each hemisphere.
