1. Yoshida, J. et al. Cerebellar contributions to the basal ganglia influence motor coordination, reward processing, and movement vigor. J. Neurosci. 42, 8406–8415 (2022). This review presents evidence of two projections from the cerebellum to the basal ganglia — a disynaptic projection to the dorsolateral striatum via the thalamus and a direct monosynaptic projection to the midbrain dopaminergic nuclei, the VTA and the SNc — and discusses their potential roles in motor and non-motor functions under normal and pathological conditions.

2. Bostan, A. C. & Strick, P. L. The basal ganglia and the cerebellum: nodes in an integrated network. Nat. Rev. Neurosci. 9, 338–350 (2018). This paper reviews data that show that the basal ganglia and the cerebellum are interconnected at the subcortical level.

3. Chen, C. H., Fremont, R., Arteaga-Bracho, E. E. & Khodakhah, K. Short latency cerebellar modulation of the basal ganglia. Nat. Neurosci. 17, 1767–1775 (2014). This paper demonstrates that a disynaptic cerebellar projection to the basal ganglia via the thalamus can effectively drive striatal basal-ganglia neuron activity and can relay cerebellar dysfunction to alter basal ganglia function and cause dystonia.

4. Carta, I., Chen, C. H., Schott, A. L., Dorizan, S. & Khodakhah, K. Cerebellar modulation of the reward circuitry and social behavior. Science 363, eaav0581 (2019). This paper reports that monosynaptic projections from the cerebellum to the VTA may contribute to reward processing and social behaviors.
