Figure 4. Time course of long afferent inhibition (LAI).

Figure 4

The effect of median nerve stimulation (2.5 × PT) is tested on a 1mV test MEP from FPB (black diamonds) and ADM (white triangles). Each square or diamond represents the mean of 80 measures (8 subjects). Median nerve stimulation inhibits the FPB MEPs at all but the 50 ms and the 100 ms ISI. Stars indicate the ISIs at which the mean conditioned MEP was statistically different from the mean test MEP (paired t-tests).
