This new type of brain model, which can be easily disassembled into 15 parts, includes cortical hemispheres, made out of transparent plastic. This novel approach allows the internal brain structures (subcortical structures and nuclei) to be easily visualized in relation to the cortical surface. This is particularly instructive since the essential structures and the cerebral cortex, such as the central sulcus (sulcus centralis) and lateral sulcus (sulcus lateralis or Sylvius’ fissure), are readily identifiable on the transparent cortex. As a result, points of reference are naturally provided between the features of the cortical surface and the underlying brain structures such as the insular cortex, corpus callosum, fornix, and the limbic system.

The brain stem itself can be dismantled into 12 pieces. On the left side the striate body (corpus striatum) can be completely removed from under the insular cortex, while on the right side the lenticular nucleus can be taken out. In addition, the complete ventricular system can also be released from the brain stem, and it can then be built together with the left half of the brain stem into the transparent brainmodel as a single part as to illustrate the topographic relationship between different portions of the ventricles and the cortical structures.

The brain stem and cerebellum are fastened to the posterior portion of the base of the skull (posterior cranial fossa of the occipital bone) and the sphenoid bone including the sella turcica where the pituitary body lies. The complete brain model is connected to the cervical vertebral column, which also shows the vertebral artery (A. vertebralis).

The middle portion of the dura mater with the opened superior sagittal sinus has been constructed so that it stabilizes the transparent hemispheres of the model. Thus, the right half of the transparent cortex can be removed to provide access to the interior of the brain. Another innovation incorporated in this model is the representation of the limbic system. It is shown in its entirety (fornix, indusium griseum and temporal hippocampus with gyrus dentatus, etc.) and can be removed from the rest of the model in one piece.

The plexus and the taenia of the choroidal plexus are marked in color.

The exit of the cranial nerves can be easily recognized on the base of the brain stem, so that relationship between the cranial nerves, the base of the skull, and the cervical vertebral column is easily demonstrated.
