We ask what cerebellum and basal ganglia “do,” arguing that cerebellum tunes motor schemas and their coordination. We argue for a synthesis of models addressing the real-time role and error signaling roles of climbing fibers. “Synthetic PET” bridges between regional and neuro-physiological studies, while “synaptie eligibility” relates the neurochemis-try of learning to neural and behavioral levels.
