FIGURE 2-5 The Cerebral Cortex Each cerebral hemisphere is divided into four lobes: frontal, parietal, temporal, and occipital, shown at left as oriented in the head. The brain surface, or cerebral cortex, shown in the frontal view, is a thin sheet of nerve tissue, heavily folded to fit inside the skull. Your right fist can MAP the orientation of the left hemisphere and its lobes.
