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 H<sub>2</sub> 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.
Lesions in this area can result in dyskinesias such as chorea-like movements.
