The term cerebrum refers to one of three basic components of the central nervous system (CNS) segmented on the basis of embryogenesis, connectivity and function ( Swanson-2004 ). The others are the cerebellum and the cerebrospinal trunk. In the classical segmentation of the CNS on the basis of topology and internal structure, the cerebrum is equivalent to the endbrain component of the forebrain.
     Historically the term cerebrum has been used for several different parts of the CNS including the whole brain, the cerebral hemispheres and the sum of cerebral cortex and adjacent cerebral white matter. A thorough discussion of the definitional history is to be found in Anthoney-1994.
