| Outline of Final Research Achievements |
This study aimed to investigate the relationship between the resting-state brain activity and motor learning using fMRI. The visuomotor tracking was used in the MRI scanner as a motor learning task. We first trained the classifier to discriminate between motor learning trials versus control trials using the activation patterns within the primary sensorimotor cortex, then applied the trained classifier to the resting-state activity before/after the motor learning sessions. The result showed a significant increase in the number of volumes classified as the task in the post-learning rest-period compared with those for the pre-learning period. Our finding revealed the reactivation of task-related patterns in the primary sensorimotor cortex for visuomotor learning. In addition, we provided the similarity of activities with the motor learning period as a neurofeedback score and found an increase in similarity during the neurofeedback period.
