The effect of yoga meditation on electroencephalography (EEG) was first recorded by Anand et al.[14] In 1961 in a controlled study conducted at the AIIMS, the EEG of four yogis was recorded both during rest and during meditation. All subjects displayed considerable alpha activity during the resting state and this activity became more prominent, with increased amplitude, during meditation. During rest, visual and auditory stimuli block the alpha activity, whereas during meditation these stimuli fail to block the alpha activity, indicating the absence of external influence on the EEG in the meditation state. Arambula[15] studied the effects of Kundalini Yoga meditation on EEG. The study subjects were physicians who practiced Kundalini Yoga meditation. Respirarition, heart rate, EEG, skin conductance, and blood pressure were monitored at baseline, during meditation, and post meditation. There was more alpha amplitude during meditation (M = 1.7/μV) than at baseline (M = 0.47 μV) or post meditation (M = 0.78 μV). Increased theta amplitude was seen during meditation (M = 0.62 μV) and before meditation (M = 0.26 μV). Bagchi and Wenger[16] also studied the effects of breathing exercises and found that some of their subjects, especially the experienced ones, could produce bi-directional changes in every autonomic variable that the experimenters measured. Further evidence that contemplative practice produces different physiological profiles was provided by Anand[17] who studied four yogis and found that they exhibited persistent alpha activity with increased amplitude during the state of trance. Prominent alpha band activity and cardiac rhythm modulation were observed after adjuant Yoga therapy in patients with refractory epilepsy.[18]
The practice of Yoga regulates body physiology through control of posture, breathing, and meditation. The effects of Yoga on the autonomic functions of patients with refractory epilepsy, as quantified by standardized autonomic function tests, were determined. The Yoga group showed significant improvement in parasympathetic parameters and a decrease in seizure frequency scores.
