Evaluating Acupuncture Point and Nonacupuncture Point Stimulation with EEG: A High-Frequency Power Spectrum Analysis

Figure 2

The absolute and relative power of the high beta waves in the 1st experiment (APS, NAPS, and NS). For APS, no distinctive changes were observed. For NAPS, AHBP and RHBP tended to increase in all channels during stimulation and decrease after stimulation, with significant changes in AHBP in 3 channels and in RHBP in 7 channels. For NS, AHBP tended to increase after stimulation compared to before stimulation, and RHBP tended to increase during stimulation and decrease after stimulation, with significant changes in two channels. .
