![]() Our findings are also relevant to the development of the high-end biofeedback systems.Ĭitation: Volodina M, Smetanin N, Lebedev M, Ossadtchi A (2021) Cortical and autonomic responses during staged Taoist meditation: Two distinct meditation strategies. These results suggest that two distinct meditation strategies could be used by experienced meditators, which partly explains the inconsistent results reported in the earlier studies evaluating meditation effects. The duration and type of previous meditation experience or any baseline indicators we measured did not explain the segregation of the meditators into these two groups. The other subgroup exhibited mind concentration patterns primarily noticeable in the EEG recordings while no autonomic responses occurred. One subgroup showed several signs of general relaxation evident from the changes in heart rate variability, respiratory rate, and EEG rhythmic activity. In the experienced meditators group we identified two subgroups with different physiological markers dynamics. All subjects followed the same instructions split into 16 stages. We recorded EEG, respiration, galvanic skin response, and photoplethysmography. We measured the physiological changes at rest and during the guided Taoist meditation in experienced meditators and naive subjects. ![]() Here we investigated the dynamics of multiple neurophysiological indicators during a staged meditation session. Numerous investigations of these correlates reported controversial results which prevented a consistent depiction of the underlying neurophysiological processes. ![]() Meditation is a consciousness state associated with specific physiological and neural correlates.
