Effects of parietal ccPAS on the PPC–M1 interaction. The mean MEP amplitudes for all 3 ISI (4, 6, and 8 ms) are expressed as percentage of the unconditioned MEP amplitude (TS alone) at each time point. Repeated-measures ANOVA showed an effect of ISI only at baseline, and a significant potentiation of MEPs was noted at ISI of 8 ms. This facilitating the effect of PPC on the ipsilateral M1 faded gradually after PPC–M1 ccPAS. *P < 0.05. TS: test stimulus alone.
