Figure 5. — Phase-dependent MEP size modulation during 20 Hz tACS. Single pulse, intracortical facilitation (ICF), and short-interval intracortical inhibition (SICI) MEP amplitude modulation. The least and the most effective tACS phases are shown for a representative participant. During the single pulse protocol, 90° was the worst phase (smallest MEP) and 270° was the best one (biggest MEP). During both ICF and SICI, 0° was the worst phase (less MEP facilitation during ICF and less MEP inhibition during SICI) and 270° was the best one (greater MEP facilitation during ICF and more MEP inhibition during SICI). Note the different y-axis scales for the 3 protocols.
