Electroencephalograms (EEGs) during Chinese qigong and Japanese Zen meditation (Zazen) were measured from the same subject, who has been training in Zen for about 22 years and qigong for about 10 years. The author, Kawano, had reported at the last symposium the differences of EEGs among qigong and the two types of Zazen, Goto and Rinzai. The experiment had used different subjects for each, so, the results involved the data caused by personal differences.
However, the present data by one trainee gave almost similar results. The indicator of concentration, Tau-m (a phase-difference between O1 and Fpl), became smaller during qigong and the concentrating type of meditation, like Rinzai. Alpha wave frequency became slower by the very quiet and deep meditation. The change in alpha-power was a little during qigong. During meditation, the alpha-power tended to become larger with time.
