Double-blind tests of qi transmission from qigong masters to untrained volunteers: (2) changes in the brain waves of qi-receivers

Electroencephalograms (EEGs) of three Chinese qigong masters and three healthy and sound Japanese men as their receivers were measured simultaneously for each pair. Two of these pairs were examined under double-blind test conditions, by which the qi-receivers, as well as all researchers, could not know the time when the qigong masters emitted qi. We have previously reported that the changes in the EEGs of qigong practitioners while emitting qi appeared as similar changes in the EEGs of their subjects. In this report no clear synchronized changes were found in the beta waves.

The alpha phase difference between the occipital and frontal regions (tau m) of qigong masters becomes significantly shorter during qigong. Even under the double-blind test conditions, the tau m of the receivers also became shorter during qigong than that during the resting state. During quiet qigong meditation by the practitioner, there was a small influence on his subject. The alpha peak-frequency of the three masters became faster during qigong, and this was reflected in the receivers. The power value of the alpha waves tended to decrease during qigong, as we have reported before. However, its changing rate was small. These results show that 'qi' is not merely a so-called placebo, but something that can be transmitted trans-personally.
