Exploration of the brain from its lateral aspect
Interventricular foramen, column of fornix and mammillothalamic tract
The thalamus and internal capsule have been cut away to expose structures in the vicinity of the interventricular foramen (3). The choroid plexus seen in the central part of the lateral ventricle continues through the interventricular foramen into the roof of the third ventricle.
