Mean response latency (+1 SE of the mean, group n = 20) in the addition (PASAT) and subtraction (PASST) tasks, before and after cerebellar tDCS. There was a trend for mean response times on the subtraction task, but not the addition task, to decrease more after cathodal, than after anodal or sham stimulation. The change in response speed between pre- and post-tDCS sessions for each task is more clearly shown in Fig. 4.
