SP duration evoked by single- (circle) and paired-pulse TMS with 1 ms (diamond) and 2.5 ms (rectangle) interstimulus intervals (ISIs) at different test stimulation (TS) intensities. SP durations were significantly shortened in paired-pulse trials at 1 ms ISI at the test intensities of 160% or higher of the active motor threshold (AMT). SP durations in paired-pulse trials with 2.5 ms ISI were not statistically different from the control trials, although they were approximately 10 - 15 ms shorter (*different from control; p < 0.0167).
