Exploration of the brain from its superior aspect

Anterior nucleus of thalamus and mammillothalamic tract; inferior horn of lateral ventricle

The thalamus has been further dissected by cutting away a part of the anterior nucleus and exposing the mammillothalamic tract in its course into this area. The tapetum has been removed to display the inferior horn of the lateral ventricle, the tail of the caudate nucleus and the downward continuation of those fibers of the stratum zonale of the thalamus seen in the previous view.
