A section through the cerebral hemispheres, hypothalamus and metencephalon.
Observe:
1. The medial and lateral striatal ridges of the striatal part of the cerebral hemispheres.
2. The interventricular foramen connecting the lateral and third ventricles.
3. The amygdala area in the rostral part of the temporal lobe area.
4. The primordial nuclei in the metencephalon.
5. The choroid plexus and median aperture of the ependymal diverticulum in the roof of the fourth ventricle.
