Human brain in head. Computer artwork of a side view of the human brain coloured to illustrate different lobes and regions. Lobes are the broad surface regions of each hemisphere that are named after the overlying bones in the skull. The main regions seen here are: the frontal lobe (purple); temporal lobe (yellow); parietal lobe (pink); occipital lobe (orange); cerebellum (red) and brainstem (blue). The lobes make up the cerebrum, the most highly developed area of the brain. Higher conscious thought processes occur here with coordination of voluntary activity. The cerebellum maintains muscular coordination & body balance, the brainstem controls vital functions.
