The lenticular fasciculus is a tract connecting the globus pallidus (internus) to the thalamus and is a part of the
thalamic fasciculus
The thalamic fasciculus is a component of the subthalamus. It is synonymous with field H1 of Forel. Nerve fibres form a tract containing cerebellothalamic (crossed) and pallidothalamic (uncrossed) fibres, that is insinuated between the thalamus a ...
. It is synonymous with
field H2 of Forel. The thalamic fasciculus (composed of both the lenticular fasciculus and
ansa lenticularis
The ansa lenticularis (''ansa lentiformis'' in older texts) is a part of the brain, making up the superior layer of the substantia innominata. Its fibers, derived from the medullary lamina of the lentiform nucleus, pass medially to end in the thal ...
) runs to the
thalamus
The thalamus (from Greek θάλαμος, "chamber") is a large mass of gray matter located in the dorsal part of the diencephalon (a division of the forebrain). Nerve fibers project out of the thalamus to the cerebral cortex in all directions, ...

Basically, it is part of a pathway that connects the
globus pallidus
The globus pallidus (GP), also known as paleostriatum or dorsal pallidum, is a subcortical structure of the brain. It consists of two adjacent segments, one external, known in rodents simply as the globus pallidus, and one internal, known in rod ...
and the thalamus.
Lesions in this area can result in dyskinesias such as chorea-like movements.
