Outline of Final Research Achievements

This study aimed to investigate the relationship between individual finger movement abilities and their cortical sensorimotor map. In our experiment, participants performed individual finger-tapping of four digits (index, middle, ring, and little fingers), which was visually cued by a single Japanese character. Synchronized with the timing of this visual cue, the subjects made repeated tapping movements with the same finger 12 times, once for every second. Our results showed that the individual piano experience affects the multi-voxel pattern activities in the primary sensorimotor cortex. Furthermore, the neurofeedback was used to increase the activities in the primary sensorimotor cortex to enhance the motor learning.
