Figure 1From: Dual-hemisphere tDCS facilitates greater improvements for healthy subjects' non-dominant hand compared to uni-hemisphere stimulationEffects of three tDCS stimulation conditions on finger-sequence performance. The mean percentage of change in the total number of correct sequential keystrokes across all subjects (N = 16) for sham, uni-hemisphere, and dual-hemisphere tDCS. Error bars signify the standard error of the mean (SEM). Dual-hemisphere tDCS improved finger-sequence coordination for the left hand significantly more than uni-hemisphere or sham stimulation.Back to article page
