| Outline of Final Research Achievements |
Long-term depression at parallel fiber-Purkinje cell synapses seems to play the essential role in cerebellar motor learning, but recent experiments demonstrate multiple plasticity mechanisms at distributed sites within the cerebellum. The present study aimed to clarify the synergistic role of those plasticity mechanisms for motor learning from the theoretical view point. We proposed a unified theoretical framework for cerebellar motor learning, and varidated our theory by large-scale computer simulation. We also built a very large-scale realistic cerebellar model on a supercomputer. Finally, we reconciled the computational principle of the cerebellum, and suggested that the cerebellum with multiple plasticity mechanisms could perform much stronger computation than that used to be considered as a perceptron.
