Modulation of Brain Electroencephalography Oscillations by Electroacupuncture in a Rat Model of Postincisional Pain

Figure 2

Changes of EEG power spectra in the postincisional pain model of rats. (a) The average of absolute EEG power before the incision (black line) and after the incision (red line). The -axis represented power value, and -axis represented frequency bands. (b) The relative power (normalized to the overall power) at 5 frequency bands. A significant increase of relative power at theta, alpha, and beta frequencies as well as a decrease at delta frequency was observed after the incision (red columns), compared with the power before the plantar surgery (black columns). , compared with before incision. All data were expressed as means ± SEM.
