Somatosensory Evoked Potentials. (A) Left: Grand average (N = 14) somatosensory evoked potential (SEP) traces recorded from electrode site CP3 for the three TMS conditions (Sham-sham, Sham, cTBS). Potentials of interest are marked on trace. The vertical dashed bar represents onset of median nerve stimulation. Black trace (Pre) is before TMS intervention and red trace (Post) is after TMS intervention. *Denotes significant amplitude difference (p < 0.05). Right: Grand average (N = 14) N70 to P50 peak to peak amplitude in microvolts (μV) with ± SEM. *Denotes p < 0.05. (B) Left: Grand average (N = 14) SEP traces recorded from electrode site F3. Potentials of interest are marked on trace. *Denotes significant amplitude difference (p < 0.05). Right: Grand average (N = 14) N30 to P14 peak to peak amplitude in microvolts (μV) with ± SEM. *Denotes p < 0.05.
