Experiment 3: Crossover trial assessing how pregabalin prevents capsaicin-induced modulation of N13 somatosensory evoked potentials (SEPs) and Secondary Hyperalgesia. Boxplots of the N13 amplitudes and magnitude of secondary hyperalgesia (NRS 0–100) at different time points (placebo in red, pregabalin in blue). Pregabalin prevented capsaicin induced facilitation of N13 and attenuated that of hyperalgesia ratings. Black lines represent medians, crosses represent means. Asterisks indicate significance vs. baseline (Sidak-corrected p-value), *p < 0.05, **p < 0.01, ***p < 0.001.
