Abstract

Long-term Vipassana meditators sat in meditation vs. a control rest (mind-wandering) state for 21 min in a counterbalanced design with spontaneous EEG recorded. Meditation state dynamics were measured with spectral decomposition of the last 6 min of the eyes-closed silent meditation compared to control state. Meditation was associated with a decrease in frontal delta (1-4 Hz) power, especially pronounced in those participants not reporting drowsiness during meditation. Relative increase in frontal theta (4-8 Hz) power was observed during meditation, as well as significantly increased parieto-occipital gamma (35-45 Hz) power, but no other state effects were found for the theta (4-8 Hz), alpha (8-12 Hz), or beta (12-25 Hz) bands. Alpha power was sensitive to condition order, and more experienced meditators exhibited no tendency toward enhanced alpha during meditation relative to the control task. All participants tended to exhibit decreased alpha in association with reported drowsiness. Cross-experimental session occipital gamma power was the greatest in meditators with a daily practice of 10+ years, and the meditation-related gamma power increase was similarly the strongest in such advanced practitioners. The findings suggest that long-term Vipassana meditation contributes to increased occipital gamma power related to long-term meditational expertise and enhanced sensory awareness.

  • Cahn et al. described increased gamma activity over parieto-occipital electrodes during open-monitoring Vipassana meditation that focuses on somatic sensation.

    “Cahn et al. [17] have described increased gamma activity over parieto-occipital electrodes during open-monitoring Vipassana meditation that focuses on somatic sensation”
  • No significant differences were found between alpha amplitude during meditation and the control mind-wandering task in the Vipassana group.

    “In line with previous findings [17], no significant differences were found between alpha amplitude during meditation and the control mind-wandering task in the Vipassana group.”
  • The study contrasts with other EEG studies finding state effects in the EEG power spectrum in various meditation practices.

    “As such, our study contrasts with other EEG studies finding state effects in the EEG power spectrum in various meditation practices [16–18, 72].”
  • Other studies have reported higher baseline and state-related increases in gamma power in long-term Tibetan Buddhist practitioners, Vipassana meditators, and meditators in other traditions, indicative of a more highly alert and aware brain state.

    “Other studies have reported higher baseline (trait) and state-related increases in gamma power in long-term Tibetan Buddhist practitioners,124 Vipassana meditators,146 as well as meditators in other traditions,150 which are indicative of a more highly alert and aware brain state.”
  • Localized frontal midline theta increases have been more consistently obtained in meditators, especially during focused attention practices, indicative of concentrated cognitive engagement.

    “Instead, localized frontal midline theta increases have been more consistently obtained in meditators,145–147 especially during FA practices, indicative of the concentrated cognitive engagement indexed by frontal midline theta.148,149”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
