Results
The significant increases of MEP and the significant decrease of SICI was observed at least for 60 min after anodal tDCS only when participants paid attention to their hands. In contrast, no significant changes in ICF was observed in all conditions. In the experiment 2, the combination of tDCS and attention to the hand significantly enhanced the acquisition of ballistic thumb movement. The higher performance was retained 7 days after the stimulation.
