Effects of SKY & P on body, mind and emotions : Pertinent issue is whether practices of SKY & P and other yogic and meditative states bring about changes in the functioning of the brain, in our attitudes, thinking, emotions and in our body physiology and/or pathology. There are suggestions that even though broad outlines of neural connections are genetically determined, synaptic transmissions and neurotransmitter profile of human brain is subject to change. This phenomenon, called as neural plasticity, is utilized by yogic practices, breathing processes and meditative states, to bring about changes in the structure and function of the brain.

Dr. Manveer Bhatia of the Neurology department of AIIMS analysed computer based data of EEG done during SKY & P among regular practitioners, as also their resting EEG. She demonstrated changes in alpha, beta and theta activity and increase in galvanic skin resistance (GSR). Changes observed suggested, increased connectivity and greater information processing. The central midline theta activity and increased beta activity along with an increase in GSR suggested activation and the increased alpha suggested relaxation. Thus there was a combination of relaxation and activation during SKY. Part of this work has been accepted for publication in Indian Journal of Physiology & Pharmacology.
