Definition: cerebrum from Philip's Encyclopedia

Largest and most highly developed part of the brain, consisting of the cerebral hemispheres separated by a central fissure. It is covered by the cerebral cortex. It co-ordinates all higher functions and voluntary activity. The cerebrum is divided into hemispheres and four lobes, including paired frontal lobes that are the areas for learning and personality.
