This cross-sectional study was conducted to see the effect slow and deep respiration on EEG activity in experienced Yoga practitioners at the Department of Physiology at AIIMS, Bhopal, India. The duration of the study was about one year. EEG was taken and was analyzed by Dinamika - Advanced Test System, Moscow, Russia.
