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.

Summary Article: cerebrum
from The Penguin Dictionary of Psychology

The largest and most prominent structure of the brain. It consists of two hemispheres separated by the longitudinal fissure, below which are the three cerebral commissures connecting the two halves. The inner core is composed of white matter made up of myelinated fibres and the grey basal ganglia; the outer covering (the cerebral cortex) is made up entirely of grey matter. The human cerebrum consists of perhaps 15 billion cells and is the latest brain structure to have evolved. It is involved in processing and interpretation of sensory inputs, control over voluntary motor activity, consciousness, planning and executing of action, thinking, ideating, language, reasoning, judging and the like; in short, all of those functions most closely associated with the so-called ‘higher mental functions’.
