Natural size, in SOMSO-Plast, after Prof. Dr. J. W. Rohen, Department of Anatomy of the University of Erlangen.  Separates altogether into 15 parts as follows: cerebral hemisphere (2), temporal and occipital lobes with limbic system, cerebellum, frontal lobe, corpus callosum, brain stem (2), corpus striatum, insula (2), nucleus lentiformis (left), internal capsule (right), ventricles of the brain, base of the skull as base.

This extended form of the brain model shows the position of the most important centers of the cerebral cortex, which have been marked in color on the left hemisphere and provided with the official numbers of Brodmann’s cytoarchitectural map of the human cerebral cortex. The primary and secondary motor (red) and sensory (blue) cortical fields, the different speech centers, auditory cortical fields and the visual cortical fields as well as the structures of the limbic system (fornix, cingulum, hippocampus etc.) are especially indicated. The three dimensional structure of the brain and the interrelationship of the different cerebral areas become evident when the model is gradually dismantled. However, one must bear in mind that the “centers“ of the cerebral cortex are not centers in the true sense of the word but rather areas with a predominant function which can not be sharply demarcated from their surrounding structures. The higher centers of the frontal lobe responsible for the general motivation of movements and motor activity as the higher centers of the temporal lobe, responsible mainly for memory and sensory integration are not marked in color.
