Unsupervised nonmotor learning in the human cerebellum

A core motor function of the cerebellum is error-based learning: it uses prediction errors--mismatches between predicted and actual sensory feedback--to refine actions.

A core motor function of the cerebellum is error-based learning: it uses prediction errors--mismatches between predicted and actual sensory feedback--to refine actions. One provocative hypothesis is that the cerebellum performs similar computations in cognitive domains. Here, we…
