| Outline of Final Research Achievements |
In this study, we used MRI to visualize how the brain develops motor functions during the so-called "golden age" of elementary school. In the motor cortex, we found that interhemispheric inhibition and cross-somatotopic inhibition develop from elementary to junior high school, suggesting that functional differentiation of somatotopic body representation matures during adolescence. As for the cerebro-cerebellar network, we showed that functional connectivity within local region is still strong in elementary school children, and the connectivity between the motor cortex and the cerebellum is enhanced along with development in association with cerebro-cerebellar fiber maturation.
