tES neuromodulation efficacy: mean across subjects. Representation of the mean for 16 subjects for tACS, tIDS, and sham, and the mean for 11 subjects for tRNS and tIDSlow. A, Means of the logarithmic transformed amplitudes of the TMS MEPs with tES off (while bars) and tES on (color codes in figure for the four current modulations and sham). B, Means across subjects of the normalized MEPs during tES on and tES off (see Materials and Methods): each MEP divided for the mean in baseline; thus, the tES off mean of the normalized MEPs is always 1. Vertical bars represent SEs. Differing values between the contrasted conditions: **p < 0.010; *p < 0.100.
