文摘

TMS-evoked potentials were reduced following LICI with interstimulus intervals (ISIs) of 100 ms and 150 ms. Inhibition of P30 was observed following LICI at 100 ms, but was absent following LICI at 150 ms. Topographical analyses suggested that global inhibition of P30, N40 and P180, but not N100, differed between ISIs. Our findings suggest that LICI at different ISIs likely has complex contributions from common mechanisms.
