Researchers have conducted the first electrophysiological study of advanced meditators, who achieve what is sometimes called “pure awareness,” and they claim meditation packs more than a tool to relieve stress. They go so far to claim advanced meditators display scientifically measurable evidence of the remarkable capacities of human consciousness, according to a paper pre-published on 23 September.

The researchers from Stanford and Harvard universities speculate that accessing this awareness state – through meditation or other ways — could neurologically “reset” the mind at a fundamental level; loosen “repetitive loops of perception, thought, or self-narration”; and increase its capacity for new insight. For scientific purposes, the researchers refer to pure awareness as “enhanced cessation” (EC).
The study was led by Kenneth Shinozuka of Stanford’s Department of Psychiatry and Behavioral Sciences, who achieved renown for delivering a TEDTalk as a teenager. Subsequently, he decided to research consciousness, saying, “No other field of research is more important for elevating human and animal welfare”.
Shinozuka’s team conducted electroencephalography (EEG) and magnetoencephalography (MEG) recordings of five advanced Buddhist meditators. They compared the recordings with neural correlates of other known states of consciousness.
All five meditators reported their thinking, feelings, and body sensations ceased during the onset of pure awareness or EC. Conscious experience was completely absent. They lost all sense of their individual self or ego. Also, they experienced no separation between self and environment.
Yet at the same time, four of five meditators reported a strong clarity of mind, the presence of a pristine awareness. After meditation, their awareness of their mind, bodily sensation, and thinking returned. In fact, all participants experienced extreme sensory vividness, and a sense of strong and lasting peace.
The neuroelectrophysiological correlates of EC reflect this rare experience: cessation of all normal awareness for minutes or hours, yet surprisingly enhanced neural complexity. EC elevated what is called Lempel-Ziv complexity [LZc], phase-normalised LZc, permutation entropy, and/or integrated information in most participants. Enhanced Cessation, therefore, is unlike the unconsciousness of sleep, anesthesia, and disorders of consciousness when awareness ceases, but also mental richness. It also is different than psychedelic episodes.
“These features suggest that EC constitutes a unique, volitionally induced state that may serve as a novel model system for studying the boundaries and mechanisms of conscious awareness”, the research paper states.
The study was conducted at the Harvard Meditation Research Program, whose director Matthew Sacchet posted on X: “What’s perhaps most promising and exciting is that EC may provide a unique experimental window into what philosophers have called ‘pure consciousness’ or ‘minimal phenomenal experience’ — and the awe-inspiring afterglow of this strange yet scientifically observable state could have far-reaching implications for wellbeing, resilience, and farthest reaches of human flourishing”.
