| Outline of Final Research Achievements |
In this study, we performed several empirical researches to identify predictors of individual differences in sensorimotor skills of heterogeneous groups of musicians (healthy pianists and pianists affected by focal dystonia) as a model of experts. Here we focused on neuroplasticity of the mechanism integrating sensory information in the somatosensory and auditory domains and motor control, by using robotics techniques, neurophysiological assessments, and machine learning analyses. We found abnormalities of the somatosensory-motor integration in pianists with focal hand dystonia, and adaptation of the nervous and musculoskeletal systems responsible for the dexterous had-use. The results were published on several international journals.

脳神経可塑性は，卓越した技能の獲得を担うだけではなく，その機能異常は局所性ジストニアなどの脳神経疾患の発症に関わっている．本研究は，特に感覚運動統合に関わる脳神経系の可塑的変化が，手指の巧緻運動技能の失調や洗練に関わる機序を明らかにしただけではなく，筋骨格系と脳神経系の相補的な適応機序が精緻な運動制御に関わることを，独自の手指外骨格システムと非侵襲脳刺激システムおよび機械学習を組み合わせることにより明らかにした．
