Table 1. Summary of baseline excitability measures in the different IPI conditions.

Condition	RMT	SI_1mV	MEP
IPI₁₀	40.1 ± 2.1	50.8 ± 2.2	0.97 ± 0.04
IPI₃₀	39.3 ± 1.6	51.4 ± 2.0	0.91 ± 0.05
IPI₆₀	38.9 ± 1.8	50.5 ± 2.4	0.93 ± 0.04
IPI₁₈₀	38.8 ± 1.4	49.6 ± 1.7	1.02 ± 0.05

Abbreviations: IPI, inter-PAS_LTP interval [in min, index]; MEP, motor-evoked potential [in mV]; RMT, resting motor threshold [in %maximum stimulator output, MSO]; SI_1mV, stimulation intensity that induces MEPs of 1mV peak-to-peak amplitude on average [in %MSO].
