這研究的目標是觀察在經過在針灸內關穴的手工刺激後，人腦腦波的動態變化，且實驗中有6位身體健康以及沒有神經上疾病的志願受測者，利用12個頻道的腦電波圖擷取儀器來紀錄一共18次的針灸刺激實驗數據。而在量測數據中，為了減少人為雜訊的干擾，會使每位受測者處於清醒以及閉眼的狀態，之後使針垂直扎進內關穴位後，手動捻針約15秒鐘來達到得氣的感覺，最後讓針留在適當的位置30分鐘才移除，接著紀錄出針之後的數據。實驗中採取內關穴是因為它與心血管循環系統有關，且已經被使用在治療冠狀心臟病過程中，且每次分析腦電波圖的數據都會與沒有刺激的背景值來比對，看是否在Delta, Theta, Alpha, Beta和Gamma這些頻帶有明顯且有意義的變化。
結果分為四個部分。第一，經過針灸刺激後，在alpha頻帶的能量強度全部上升；第二，腦波的電位在針刺期間以及針刺後會變更高；第三，在Alpha頻帶的峰值頻率有同步的現象；第四，同步峰值頻率的變化與心率頻率的變化有同調的現象。我們假設這些影響將對生理的自動平衡有好處，且未來將研究同步腦波共振以及腦波電位升高的生理意義。

The objective of this research is to investigate the dynamic changes of human brain electroencephalogram (EEG) before and after manual stimulation of the PC 6 (Neiguan) acupuncture site. Six healthy volunteers with no neurological conditions participated in this study. Using the storage of 12-channel EEG recorder and spectral analysis techniques, data of 18 trials were obtained before, during and after acupuncture stimulation. In order to minimize artifacts, all data were collected with the subjects alert but eyes closed. Acupuncture needle was inserted perpendicularly into the PC 6 acupuncture site and manually stimulated about 15 seconds to achieve De Qi sensation. Needles were left in place for 30 min and then removed. This point was chosen because it is associated with circulatory system and has been used in the treatment of coronary heart problem. Analysis of the EEG data from each acupuncture event was compared to the baseline data to show any significant changes over the Delta (0.5-4 Hz), Theta (4-7 Hz), Alpha (7.5-12 Hz), Beta (12-30 Hz) and Gamma (30-100 Hz) frequency bands.
Results are fourfold. First, all trials have an increase in the amplitude and power of the alpha band during acupuncture. Secondly, the electric potential of the EEG is higher during and after acupuncture. Thirdly, the frequency peaks in alpha band of all 12-channels are synchronized. Fourthly, all synchronized frequency peaks shift in harmony with the frequency shifts of the heart rate. We hypothesize that these effects will be beneficial for physiological homeostasis. Further studies on the meanings of synchronized brain oscillations and higher electric potentials will be studied in the future.
