Lenticular fasciculus

The lenticular fasciculus is a tract connecting the globus pallidus (internus) to the thalamus and is a part of the thalamic fasciculus. It is synonymous with field H₂ of Forel. The thalamic fasciculus (composed of both the lenticular fasciculus and ansa lenticularis) runs to the thalamus. It is part of a pathway connecting the globus pallidus and the thalamus.
