Mean alpha power during task performance normalized to pre-stimulation trial power for successful right hand trials in the C3 and CP3 electrodes across the alpha (8-13Hz) and beta (15-30Hz) frequency bands. There is decreased alpha and beta power in the cathodal group compared to the sham group during right hand task performance in C3 immediately after stimulation and at the delayed post-stimulation time point and in CP3 at the delayed post-stimulation time point. There is no significant difference for left hand trials. Values: Mean +/− S.E. *p<0.0125 for Wilcoxon rank sum test. **p<0.05 for Kruskal Wallis test.
