Figure 1From: Modulation of the cortical silent period elicited by single- and paired-pulse transcranial magnetic stimulationRepresentative waveforms of MEP induced by TMS during sustained 30% EMG. MEP amplitude was calculated by averaging peak-to-peak amplitudes. CSP duration was defined as the time from TMS onset to the time of reappearance of an EMG amplitude that was 3-fold the standard deviation of the background EMG noise at rest.Back to article page
