From: Detecting cortical circuits resonant to high-frequency oscillations in the human primary motor cortex: a TMS-tACS study

Figure 3

Effects of 667 Hz tACS (upper line), 333 Hz tACS (middle line) and sham tACS (lower line) on MEPs amplitude in the five different TMS paradigms tested. 333 Hz tACS facilitated MEPs in AMT-biph and AMT-circ protocols. Note that the tACS-induced increase of MEPs amplitude in AMT-biph was present only during the stimulation (T1), while in AMT-circ this effect persisted at 5 minutes after tACS (T2). 667 Hz tACS and sham tACS did not induce any significant effect on MEPs. Asterisks denote significant differences in the post-hoc analyses.
