This paper presents the evident effects of acupoint stimulation, using EEG (electroencephalogram) measurements. With acupuncture stimulation and the EEG measurement on the same meridian, EEG is able to accurately detect the effects of acupunctural point stimulation on brain waves. In this study, 24 subjects without heart or neural diseases were randomly separated into two groups of 12, named test and control groups. Similar procedures are performed; the subjects lay on a bed with eyes closed for ten minutes as the baseline. The test group received acupuncture at their Waiguan points (TE5) on their left hands for 20 minutes, while the control group did not. EEGs are recorded during pre-acupuncture, acupuncture stimulation and post-acupuncture stimulation periods. The EEG electrodes are at the T3, T4, O1 and O2 locations. Continuous wavelet transformation analysis is adopted; therefore, EEGs are divided into the following bands: δ (0.54HZ), θ (48HZ), α (813HZ) and β (1330HZ). During acupuncture stimulation, the θ energy is increased and had statistical differences at all electrode points, T3, T4, O1 and O2. Upon removing the needle, the energy at the T3 and T4 points slowly declined and revealed obvious statistical differences. During acupuncture, only α energy has been noted to have statistical difference and it was increased at the T3 point. However, the energy was decreased and had no statistical difference after five minutes. Acupuncture is proven to be able to affect brain waves, as the stimulation might have changed the tissues between the cranium and scalp; therefore, the brain waves are detected more easily.
