Excitatory input {climbing fiber} from inferior olive goes to one Purkinje cell, making 300 synapses, to fire Purkinje cell. Perhaps, climbing fiber makes error-and-training signals to adjust parallel-fiber synaptic weights, teaching Purkinje cells to recognize patterns signaled by input vectors and to select movements that reduce errors. Perhaps, cerebral cortex activates climbing fiber input, to train cerebellum to recognize appropriate contexts for generating same movements more automatically.
