The cerebellum functions as an error correction system, learning to compensate for sensory or motor deficits.

“So that if your vestibular apparatus is a little bit damaged somehow, your visual system is actually talking to your cerebellum saying there's a problem here. There's an error and your cerebellum is learning to do better by increasing the output of the vestibular system to compensate for whatever that loss was. So it's a little error correction system that's sort of typical of cerebellar function and it can happen in many many different domains.”
