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

Figure 7

Phase couplings at different frequency bands: statistical analysis of the filtered wavelet bicoherence (FIWBIC) values after EA treatment in the postincisional pain model of rats. Boxplots stand for the phase coupling at local frequency bands, and the -axis represents the mean of synchronization. After EA application, the synchronization value between beta and delta/theta/alpha decreased, that is, synchronization became weaker; whereas the value between beta and gamma increased, that is, synchronization became stronger. Wilcoxon rank-sum test was used. , , , .
