Zusammenfassung

Questioning whether stimulation properties in median nerve SEPs show interactions multichannel recordings were performed in a three-factorial repeated measures design with the parameters (i) eyes opened vs. eyes closed, (ii) stimulation intensity above motor threshold (MT) vs. intensity sub MT, (iii) stimulation rate 0,5Hz vs. 9Hz resulting in SEPs recorded during eight different conditions. Varying the stimulation intensity revealed an impact on the amplitude and the latency of the N20 source activity and on the amplitude, the duration and the number of peaks of the high frequency oscillatory (HFOs) sources.
