Highlights • First simultaneous recordings of cerebellar granule cells and climbing fibers • Mice learn reward timing during operant conditioning, with cerebellar contributions • Sustained granule cell firing links action to future climbing fiber reward spiking • Granule cell-climbing fiber activity is suited to learning to track long intervals Summary In classical cerebellar learning, Purkinje cells (PkCs) associate climbing fiber (CF) error signals with predictive granule cells (GrCs) that...
