The subthalamus or ventral thalamus is a part of the diencephalon. [1] Its most prominent structure is the subthalamic nucleus . The subthalamus connects to the globus pallidus , a subcortical nucleus of the basal ganglia .
The subthalamic nucleus receives its main input from the external globus pallidus (GPe), [7] not so much through the ansa lenticularis as often said but by radiating 'comb' fibers crossing the medial pallidum first and the internal capsule (forming part of Edinger's comb system, see figure), as well as the ansa subthalamica. [8]
The fields of Forel is a complex region in the posterior subthalamus, consisting of a concentrated collection of bundles of fibers. [1] The tracts formed include the thalamic fasciculus that includes the ansa lenticularis and lenticular fasciculus, cerebellothalamic tracts, and pallidothalamic tracts. Other included fibers connect to other ...

The thalamic fasciculus is a component of the subthalamus (ventral thalamus). It is synonymous with field H 1 of Forel.Fibers from the lenticular fasciculus (field H 2 of Forel), are joined by fibers from the ansa lenticularis – different parts of the internal globus pallidus, before they enter the ventral anterior nucleus of the thalamus to form the thalamic fasciculus.

This traditional list does not accord strictly with human thalamic anatomy. Nuclear groups of the thalamus include: . anterior nuclear group [1] (anteroventral, [2] anterodorsal, [3] anteromedial [4])
Thalamencephalon (Latin: thalamencephalon), also called thalamic region (regio thalamica) or thalamic complex (complex thalamica) is a complex structure comprising thalamus (in the wider sense of the term thalamus, i.e. dorsal thalamus, or thalamus proper, plus subthalamus, or ventral thalamus) and several adjacent structures: epithalamus and metathalamus.
