Cerebral Hemispheres

There are two cerebral hemispheres of the brain, named the left and right hemispheres, which are divided into large subdivisions called lobes. Four of the lobes are on the surface of the hemispheres and are named according to the overlying cranial (skull) bones. These lobes are the frontal lobe, parietal lobe, temporal lobe and occipital lobe. A fifth lobe, the insula lies deep in the cerebrum and is covered by portions of the frontal, parietal and temporal lobes. The two hemispheres carry out different functions. Generally the left hemisphere carries out analytical and verbal functions. The right hemisphere is the source for spatial and artistic skills. The hemispheres via the connection with the corpus callosum (white matter) share memory and learning.
