This study was carried to identify whether acupuncture of several acupuncture points can affect the brain and to observe which aspects appear in EEG mapping, using electroencephalography. Those results are as follows ; 1. The pattern of resting computerized EEG map in intact human is appered normal 2. Each Acupuncture in Kwan Weon or Jog Sam Ri meridian points bring about the increase in $ heta,;alpha-wave$ activity and at various area of the cerebrium and the decrease in $delta,;eta-wave$ activity. It strands to reason that brain function is elevated On the other hand , synchronous acupuncture bring about the decrease of brain function in view of the decrease of $delta,; heta-wave$ activity at frontal area, and the unstable brain state in view of the increase of $eta-wave$ activity. 3. Acupuncture in Hyeon Jong meridian point bring about the increase of $delta,; heta-wave$ activity at frontal area and $eta-wave$ activity at temporal area. From these we deduce that brain function is declined and brain is unstable. Synchronous acupuncture with other meridian points reversly showed that brain function is elevated. 4. Synchronous acupuncture in Kwan Weon , Jog Sam Ri, Hyeon Jong bring about the decrease of the brain function and the unstable brain state, showing the pattern of increased $delta,; heta-wave$ activity at frontal, parietal area, and increased $eta-wave$ activity at temporal area.
