Spinal Excitability Changes after Transspinal and Transcortical Paired Associative Stimulation in Humans

Figure 4

Frequency-dependent depression of TEPs. (a) Nonrectified waveform averages of ankle transspinal-evoked potentials (TEPs) recorded from one representative subject at 0.2 and 1.0 Hz. (b, c) Overall percent change of TEPs recorded at 0.2 Hz from the associated TEP recorded at 1.0 Hz before and after each PAS protocol from all subjects. The abscissa shows the muscles from which TEPs were recorded. Error bars indicate SE.
