Figure 3. Intensity-dependent conditioning effects of premotor 5Hz rTMS on the excitability in ipsilateral M1_HAND.

A, effects on single-pulse excitability of ipsilateral M1_HAND The MEP amplitude at rest (top) and during tonic contraction (middle) and on the duration of the cortical silent period (bottom). B, the after effects on paired-pulse excitability are separately illustrated for intracortical inhibition at ISIs of 2 and 4 ms, intracortical facilitation at ISIs of 9 and 12 ms, and an intermediate interval of 7 ms. Error bars are standard error of the mean (s.e.m.). Asterisks denote a significant change relative to baseline.
