| 摘要 | Meditation has been likened to an extension of the wake-sleep transition on the basis of EEG studies. This study looked at patterns of EEG and respiration (alveolar Pco2, thoracic vs abdominal movement, and respiratory rate) during meditation in 3 different meditation groups (Yoga, Zen Buddhist and Tibetan Buddhist), as well as during relaxation in nonmeditating controls, and compared them to EEG and respiration patterns of normal sleep onset in the same subjects. Two or 3 meditation sessions were run on several subjects to assess stability of the findings across days. Co2 sensitivity of the respiratory centers of the brain during meditation (or relaxation in controls) and baseline was also measured. The main findings of the study were (1) a greater incidence of EEG of relaxed wakefulness (as opposed to early stage 1 sleep EEG) during meditation in the Zen meditators as compared to all other groups; (2) a greater incidence of late stage 1 sleep EEG activity in controls during relaxation as compared to the Tibetan and Zen groups during meditation; and (3) a different pattern of EEG and alveolar Pco2 changes in meditators of all groups during meditation as compared to either relaxation in controls or normal sleep onset in the same meditator subjects. Specifically, with regard to this last finding, during meditation the pattern was one of increased alveolar Pco2 when the EEG was indicative of relaxed wakefulness as well as when it was that of stage 1 sleep; whereas during both relaxation in controls and during sleep onset in all groups, the pattern was one of increased Pco2 only when the EEG was indicative of stage 1 sleep. The conclusions are that there are neurophysiological differences as well as similarities between different meditative disciplines, that meditation (as investigated here) and the wake-sleep transition do not involve identical neurophysiologic processes, and that meditation is not equivalent to simple rest. Given these findings, it is hypothesized that meditation produces a "movement" of neurophysiologic processes which normally occur closer to sleep in the wake-sleep transition (hypnagogic processes) to a higher level of arousal with more conscious awareness and access to memory. |
