Differing dose details and controlling confounding covariates in modulating motor cortex excitability by transcranial direct current stimulation

We appreciate the recent letter [1] that commented on our study of modulating motor cortex excitability by transcranial direct current stimulation (tDCS) [2]. The main point of the letter was that our reported modulation of motor evoked potentials (MEPs) by tDCS was more consistent and thus had a larger effect size than previously reported results in the literature. We agree with the author that our results are much clearer than the ones from previous studies in the field and that the standard mean difference calculated for pairwise comparisons substantially exceeds what has been previously reported.
