Objective: This single-blind, randomized study aimed to evaluate effects of acupuncture stimulation at the GV 20 point on the electroencephalogram (EEG).Methods: Data was collected from 17 volunteers, aged 18 -25 years old.EEG recordings were obtained before and after verum acupuncture and after a one-week interval EEG recording was also obtained before and after sham acupuncture.Spectral analysis of the EEG data was compared to baseline EEG.Results: Compared to baseline, there was an increase in the alpha band power at the T4 and T5 electrodes (p < 0.05) and a decrease in the beta band power at the T4, T6, and A2 electrodes following verum acupuncture.However, comparison of the data recorded before and after sham acupuncture revealed no significant differences.Conclusions: We claim that verum acupuncture stimulation at the GV 20 point has an effect on brain activity, which might be due to the known "mood modifying, relaxation effect" at that point.
