Outline of Final Research Achievements |
I proposed a computational model of the primary motor cortex (M1) in which visuomotor transformation is solved through Newton-Euler dynamics with spatial representations, and explained a variety of findings about M1 neural properties in a unified way. In addition to neural properties, the model also explained various findings from human psychophysics of motor adaptation such as generalization patterns. Extending the model of M1, I attempted to construct a model of the motor-related network including the parietal cortex and the cerebellum. Especially, I discovered, by constructing a model of cerebellar activities, a predictive computation from inputs of the mossy fibers to outputs of the cerebeller nuclei. With these models, I clarified the neural representations and the algorithms with which the brain predicts and controls body movements.
