Figure 4.

Time course of the mean energy (mA/m³) of the somatosensory steady-state response (SSSR) during the presentation of the pseudo-dynamic stimuli. The mean energy of the somatosensory gating (SG) during the first two pictures [initial gating (600:800 ms)] was significantly different from mean energy during the Cross Baseline (−200–0 ms) for each condition and for all participants. The magnitude of the SG during the initial gating (600:800 ms) was significantly greater in the Pain and NoPain conditions compared to the Neutral condition. ^***p < 0.001.
