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

Figure 4

Phase couplings at different frequency bands: statistical analysis of the filtered wavelet bicoherence (FIWBIC) values 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. The synchronization values increased between delta and alpha, between theta and theta/alpha/beta, between alpha and alpha/beta, whereas the value decreased at delta band after the plantar incision. Wilcoxon rank-sum test was used. , , , .
