Thalamic fasciculus

The thalamic fasciculus is a component of the subthalamus. Nerve fibres form a composite bundle containing cerebellothalamic and pallidothalamic fibres that is insinuated between the thalamus and zona incerta.

The thalamic fasciculus consists of the joint fibers of the ansa lenticularis and the lenticular fasciculus, coming from different portions of the medial globus pallidus, before they jointly enter the ventral anterior nucleus of the thalamus.
