Topographic EEG brain mapping during Yogic Flying

Abstract

Voluntary focal activity typically disrupts EEG alpha activity. This experiment tested the hypothesis that the alpha wave would not be disrupted during "Yogic Flying" (YF), a TM-Sidhi technique that produces movement of the body such as hopping, because the technique operates at a self-referral level in which attention remains in a settled, inwardly directed state. In 23 subjects YF was compared with voluntary jumping in the same subjects which mimicked the movements of YF. The percentage of relative power of alpha was significantly higher for YF in virtually all EEG derivations, supporting the hypothesis. The effect appeared to be of similar magnitude in all cortical areas.
