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

Figure 5

Depression of TEPs in response to paired transspinal stimuli. Nonrectified waveform averages of ankle transspinal-evoked potentials (TEPs) recorded from one representative subject upon paired pulses at interstimulus intervals of 50 and 100 ms at a constant stimulation frequency of 0.2 Hz.
