Some Aspects of Electroencephalographic Studies in Yogis
Journal/Book: Manuskriptdruck. 475-479.
Abstract: Four Yogis who practised samadhi were investigated electroencephalographically. It was observed that their resting records showed persistent alpha activity with increased amplitude modulation during samadhi. The alpha activity could not be blocked by various sensory stimuli during meditation.Two Yogis, who could keep their hand immersed in ice cold water for a5-55 min, also showed persistent alpha activity both before and during this practice.The possible mechanism of these observations has been discussed.The authors gratefully acknowledge the willing cooperation of the following Yogis for undergoing the various investigations reported in this paper: Shri Ramanand Yogi, Pandit Parkash Dev, Shri Rishi Ram, Shri N.S. Paintal, Shri Babu Ram Gupta and Shri Narain Chander Singh Ray.
