Researchers will compare 1 mA, 2 mA, and 3 mA tDCS to sham tDCS to see which intensity of tDCS is most effective in improving the ability of motor learning.\n\nParticipants will be randomly divided into four groups and receive 4 different intensities of tDCS(1 mA, 2 mA, 3 mA and sham tDCS),and will be blinded to the type of tDCS they received.
