Preview

The method of sectioning the brain at different levels along the three orthogonal planes reveals anatomical structures that are otherwise hidden from external inspection. These include the ventricular system, the deep grey nuclei, and the white and grey matter. The ventricular system consists of several cavities filled with cerebrospinal fluid (CSF), communicating through small ducts. The lateral ventricles represent the largest cavities of the cerebral hemispheres and surround a group of grey matter agglomerates that form the subcortical telencephalic and diencephalic nuclei. These nuclei are separated and surrounded by many fibres that form the white matter of the cerebral hemispheres. The outer aspect of the cerebral white matter is delimitated by the cerebral cortex. Each of these structures will be described in some detail below.
