Figure 2a. Effect of tDCSanodal (20 min) on right IF GOT thresholds. All subjects achieved a stable baseline performance prior to tDCS. Ten minutes after the onset of tDCSanodal, subjects showed a significant discrimination improvement that persisted for at least 40 minutes. The GOT thresholds on the left IF ipsilateral to tDCSanodal was not affected.
Figure 2b. Effect of tDCSsham (20 min) on right IF GOT thresholds. In comparison to tDCSanodal, there was no change in GOT thresholds neither on the right nor on the left IF.
