Neuroscientists found the cerebellum contributes to reward-based learning in primates.

Neuroscientists at the University of Pittsburgh and Columbia University have discovered that the cerebellum, previously believed to only control movement, balance, and coordination, plays a significant role in reward-based learning. The research, involving monkeys and a drug to temporarily block the posterior lateral cerebellum's activity, revealed that the cerebellum uses reward information to shape cognitive functions in primates, not just skillful actions.
