Fig. 2

Chronic pain increased high-gamma band power in the ACC. a Example of trial-averaged LFP raw trace, in the naïve condition. The panel directly below the raw trace shows trial-averaged time–frequency spectrum, with time 0 denoting the time of pinprick stimulation. b Example of trial-averaged LFP raw trace, post CFA injection. The panel directly below the raw trace shows trial-averaged time–frequency spectrum, with time 0 denoting the time of pinprick stimulation. c Z-score power in the theta frequency band (4–8 Hz) before and after CFA injection. d Z-score power in the alpha frequency band (8–15 Hz) before and after CFA injection. e Z-score power in the beta frequency band (15–30 Hz) before and after CFA injection. f Z-score power in the low-gamma frequency band (30–60 Hz) before and after CFA injection. g Z-score power in the high-gamma frequency band (60–100 Hz) before and after CFA injection (p = 0.0084, Paired t-test). Error bars represent SEM. *p < 0.05, **p < 0.01
