Table 2. Test MEP amplitudes of the eight experimental conditions.

Condition	Test MEP amplitude (mV)
TPPA (M1–CP60%AMT)	0.92 ± 0.09
TPPA (M1–CP80%AMT)	0.93 ± 0.08
TPAP (M1–CP60%AMT)	0.91 ± 0.08
TPAP (M1–CP80%AMT)	0.92 ± 0.10
TPPA (dPM–CP60%AMT)	1.03 ± 0.08
TPPA (dPM–CP80%AMT)	0.89 ± 0.08
TPAP (dPM–CP60%AMT)	0.85 ± 0.08
TPAP (dPM–CP80%AMT)	0.82 ± 0.07

Values are mean ± s.e.m. TP, test pulse; PA, anterior-directed current; AP, posterior-directed current; M1–CP, conditioning pulse applied to M1; dPM–CP, conditioning pulse applied to dPM; AMT, active motor threshold.
