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

Figure 1

Experimental procedures. After a 30-minute rest, the EEG was performed 5 times for 3 minutes per measurement, with a 3-minute rest time between measurements. During the resting time after the first EEG measurement, an acupuncture needle was inserted at the acupuncture point and removed during the resting time after the third EEG measurement. The analysis was performed by dividing the EEG into 3 parts: before stimulation (BS), during stimulation (DS), and after stimulation (AS).
