Cerebellothalamic tract

Also known as the dentatothalamic tract or the tractus cerebellothalamicus, is part of the superior cerebellar peduncle. It originates in the cerebellar nuclei, crosses completely in the decussation of the brachium conjunctivum, bypasses the red nucleus, and terminates in parts of the ventral anterior nucleus, ventral intermediate, ventral posterolateral nucleus, and central lateral nuclei of the thalamus.

It is mostly separated from the pallidothalamic tracts.^[1]

It can play a role in mediating symptoms in hereditary dystonia.^[2]

The term "cerebellothalamocortical pathway" is used to indicate termination in the cerebral cortex.^[3]

Function

The cerebellothalamic tract transmits information from the cerebellum to the thalamus via neural impulses for the sensory systems.
