Modulation of Brain Electroencephalography Oscillations by Electroacupuncture in a Rat Model of Postincisional Pain
Figure 5
Changes of EEG power spectra after EA treatment in the postincisional pain model of rats. (a) The averaged absolute EEG power after EA treatment (red curve) compared with that before EA treatment (pink curve). The -axis represented power value, and -axis represented frequency bands. (b) The averaged absolute EEG power after restriction (dark blue color) compared with that before restriction (light blue curve). The -axis represents power value, and the -axis represents the frequency bands. (c) Change of the relative power in the EA group. The relative power value in EA group was normalized as the percentage relative to that before the incision. There was a significant decrease at the beta band after EA (red bar) compared with that after the incision (pink bar). (d) Change of the relative power in the restriction group. No significant changes were observed (light blue bar versus dark blue bar). (paired t-test).
