Motor sequence performance improvement. The Y axis represents the ratios of the reaction times of the predetermined repeating sequence versus a random sequence (shaded S versus R blocks in Figure 1). The asterisk (*) represents P < 0.05 between Pre and Post 1 sessions for all stimulation types by the paired t test, which suggests motor sequence learning occurred at immediately after stimulation regardless of stimulation type. Cross(+) represents P < 0.05 between Pre and Post 2 sessions for Uni-tDCS and Bi-tDCS, but not for Sham stimulation by the paired t test, which suggests that motor sequence performance improvements were maintained after Uni-tDCS and Bi-tDCS, but not after Sham stimulation.
