Abstract: Skilled meditators can voluntarily induce unconscious states, generally known as cessations, with out using medication. This skill, noticed in Tibetan Buddhist observe, permits meditators to expertise a momentary void of consciousness, adopted by enhanced psychological readability.
Performed throughout a number of nations, the examine utilized EEG spectral evaluation to objectively measure mind exercise throughout these cessation occasions. By correlating the meditator’s first-person expertise with neuroimaging information, researchers have gained insights into the profound modulation of consciousness achievable via superior meditation practices.
- Skilled meditators can voluntarily enter a state of cessation, momentarily dropping consciousness with out exterior aids.
- The examine analyzed 37 cessation occasions in a single skilled meditator throughout 29 classes utilizing EEG spectral evaluation.
- This analysis opens new avenues for understanding consciousness modulation via meditation.

A examine reveals that skilled meditators are in a position to voluntarily modulate their state of consciousness throughout meditation. In different phrases, they’ve the weird skill, with out using medication, to induce a momentary void of consciousness throughout cessations via large-scale modulation of mind exercise.
In what conditions can a human being lose consciousness? An anesthetization, mind concussion, intoxication, epilepsy, seizure, or different fainting/syncopal episode brought on by an absence of blood move to the mind could cause complete lack of consciousness. However can unconsciousness be induced with out using medication?
Within the occasion generally known as cessation (or nirodha, in accordance with Tibetan Buddhist terminology), the meditators briefly lose consciousness, however upon re-awakening, they’re stated to expertise important adjustments in the way in which their thoughts works, together with a sudden sense of profound psychological and perceptual readability.
Matthew Sacchet, along with researchers from Australia, the Netherlands, and america, realized that the concept that a meditator has the power to “flip off” consciousness may have broad implications for our understanding of how cognition works, however in addition they discovered that earlier analysis on cessation had a number of limitations, specifically the truth that few skilled meditators have reached the extent of meditation the place cessations happen, and that cessations are additionally troublesome to foretell.
Within the article “Investigation of superior mindfulness meditation ‘cessation’ experiences utilizing EEG spectral evaluation in an intensively sampled case examine,” printed in November within the journal Neuropsychologia, the authors reveal that, on this intensive case examine, they overcame these challenges by recruiting one skilled meditator who reported having the ability to enter and report a number of cessation occasions as they emerged all through repeated meditation classes.
The researchers used a neurophenomenological method through which the “first-person” descriptions of the cessations are associated to goal neuroimaging information. In different phrases, the skilled meditator systematically evaluated the psychological and physiological processes (context, enter, occasion, output, after-effects) as he skilled them, and these evaluations have been used to group and choose occasions for subsequent EEG-based evaluation.
Spectral evaluation of EEG information surrounding the participant’s 37 cessation occasions recorded in 29 classes made it attainable to narrate the cessations to goal and intrinsic measures of mind exercise associated to consciousness and high-level psychological functioning.
In response to researcher Matthew Sacchet, “these outcomes present preliminary proof for the power of adept meditators to voluntarily and profoundly modulate their state of consciousness and lay the foundations for additional examine of those distinctive states utilizing neuroscientific and different empirical approaches”.

Investigation of superior mindfulness meditation “cessation” experiences utilizing EEG spectral evaluation in an intensively sampled case examine
Mindfulness meditation is a contemplative observe knowledgeable by Buddhism that targets the event of present-focused consciousness and non-judgment of expertise. Curiosity in mindfulness is burgeoning, and it has been proven to be efficient in enhancing psychological and bodily well being in medical and non-clinical contexts.
On this report, for the primary time, we used electroencephalography (EEG) mixed with a neurophenomenological method to look at the neural signature of “cessation” occasions, that are dramatic experiences of full discontinuation in consciousness much like the lack of consciousness, that are reported to be skilled by very skilled meditators, and are proposed to be proof of mastery of mindfulness meditation.
We intensively sampled these cessations as skilled by a single superior meditator (with over 23,000 h of meditation coaching) and analyzed 37 cessation occasions collected in 29 EEG classes between November 12, 2019, and March 11, 2020. Spectral analyses of the EEG information surrounding cessations confirmed that these occasions have been marked by a large-scale alpha-power lower beginning round 40 s earlier than their onset, and that this alpha-power was lowest instantly following a cessation.
Area-of-interest (ROI) based mostly examination of this discovering revealed that this alpha-suppression confirmed a linear lower within the occipital and parietal areas of the mind through the pre-cessation time interval.
Moreover, there have been modest will increase in theta energy for the central, parietal, and proper temporal ROIs through the pre-cessation timeframe, whereas energy within the Delta and Beta frequency bands weren’t considerably completely different surrounding cessations.
By relating cessations to goal and intrinsic measures of mind exercise (i.e., EEG energy) which might be associated to consciousness and high-level psychological functioning, these outcomes present proof for the power of skilled meditators to voluntarily modulate their state of consciousness and lay the muse for finding out these distinctive states utilizing a neuroscientific method.
