CHEPs and LEPs Grand Average. Illustrated are the grand average potentials measured at (column a) the vertex (N2P2 waveform) and (column b) contralateral electrodes C3 or C4 (N1 waveform). CHEPs are indicated with a white background and LEPs with a grey background. The blue lines illustrate the grand average of the sham condition and the red line the grand average of the capsaicin condition. Included are the 95% confidence intervals, shown with a less dense blue and red area. N2 occurs around 377 ms for CHEPs and 205 ms for LEPs. P2 occurs around 507 ms for CHEPs and 321 ms for LEPs. N = 19. N1 occurs around 327 ms and 160 ms for CHEPs and LEPs, respectively.
