Effect of inter-train interval on the induction of repetition suppression of motor-evoked potentials using transcranial magnetic stimulation
Fig 2
Repetition suppression of the motor-evoked potentials.
The effects of the stimulus order and inter-train interval (ITI) on the amplitudes are shown. The amplitudes (mean±standard deviation) are averaged and normalized to the first ones in the train (dashed line). Asterisks mark the amplitudes that differ from the first one (p<0.05) in the train according to the pairwise comparisons using Bonferroni adjustment of p-values for correction of multiple comparisons. A) All 4-pulse sequences. B) ITI 1 s. C) ITI 3 s. D) ITI 4 s. E) ITI 6 s. F) ITI 7 s. G) ITI 12 s. H) ITI 17 s. I) 20-pulse sequence. J) 120 pulses/train at inter-stimulus interval (ISI) of 1 s.
