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

Figure 6

Locations of electrodes with significant EEG power change after EA treatment in incisional pain model of rats. (a) Topographic mapping of EEG power in beta band (left) and gamma band (right) after EA application compared with that before EA application. Averaged EEG power density values were color-coded and plotted at the corresponding position on the planar projection of the epidural surface and interpolated between electrodes (dots). (b) Electrodes with statistically significant difference ( ) of power change in the beta and gamma band.
