Cross-Sectional View of the Cerebrum (White Region Indicates Location of Neurons)

Caption

Left: Cross-sectional view of the cerebrum in normal ferret. Neurons are localized in the cerebral cortex, the surface layer of the cerebrum. Since the surface of the cerebrum has folds (gyri), the layer containing neurons winds on its way. Right: Cross-sectional view of the cerebrum in TD ferret. Clusters of neurons (indicated by arrows) are found deep in the cerebrum, which are not detected in the cerebrum of normal ferret. They are called 'periventricular nodular heterotopia,' PNH. In addition, in the surface layer, a larger number of smaller folds (gyri) are seen than normal (indicated by asterisks). They are called polymicrogryri.
