Figure 3

Wavelet-extracted oscillatory amplitude waveforms at frequency layers of 7, 11, 18, 31, and 39 Hz from the averaged wavelet-transformed single trials of the self-pain (upper-quadrant) and other-pain (lower-quadrant), respectively, for Control (A, C) and Placebo Analgesia (B, D) treatments (painful electric-train onset at time 0 ms). Color current source density maps (µV/m2) are reported at the bottom for each frequency of interest (7, 11, 18, 31, and 39 Hz) and the time corresponding to each maxima amplitude for each frequency.
