NeuroNames |

NeuroLex ID |

The dentatothalamic tract (or dentatorubrothalamic tract) is a tract which connects the dentate nucleus and the thalamus while sending collaterals to the red nucleus.[1]
The term "dentatorubrothalamocortical" is sometimes used to emphasize termination in the cerebral cortex.[2]
