People Experience 'New Dimensions of Reality' When Dying, Groundbreaking Study Reports (vice.com) 110

An anonymous reader quotes a report from Motherboard: Scientists have witnessed brain patterns in dying patients that may correlate to commonly reported "near-death" experiences (NDEs) such as lucid visions, out-of-body sensations, a review of one's own life, and other "dimensions of reality," reports a new study. The results offer the first comprehensive evidence that patient recollections and brain waves point to universal elements of NDEs. During an expansive multi-year study led by Sam Parnia, an intensive care doctor and an associate professor in the department of medicine at NYU Langone Health, researchers observed 567 patients in 25 hospitals around the world as they underwent cardiopulmonary resuscitation (CPR) after suffering cardiac arrest, most of which were fatal.

Electroencephalogram (EEG) brain signals captured from dozens of the patients revealed that episodes of heightened consciousness occurred up to an hour after cardiac arrest. Though most of the patients in the study were sadly not resuscitated by CPR, 53 patients were brought back to life. Of the survivors, 11 patients reported a sense of awareness during CPR and six reported a near-death experience. Parnia and his colleagues suggest that the transition from life to death can trigger a state of disinhibition in the brain that "appears to facilitate lucid understanding of new dimensions of reality -- including people's deeper consciousness -- all memories, thoughts, intentions and actions towards others from a moral and ethical perspective," a finding with profound implications for CPR research, end-of-life care, and consciousness, among other fields, according to a new study published in Resuscitation. [...]

"One of the things that was unique about this project is that this was the first time ever where scientists had put together a method to examine for signs of lucidity and consciousness in people as they're being revived by looking for brain markers, or brain signatures of consciousness, using an EEG device as well as a brain oxygen monitor," Parnia explained. "Most doctors are taught and believe that the brain dies after about five or 10 minutes of oxygen deprivation," Parnia said. "One of the key points that comes out of this study is that that is actually not true. Although the brain flatlines after the heart stops, and that happens within seconds, it doesn't mean that it's permanently damaged and [has] died. It's just hibernating. What we were able to show is that actually, the brain can respond and restore function again, even after an hour later, which opens up a whole window of opportunity for doctors to start new treatments." Indeed, the study reports that "near-normal/physiological EEG activity (delta, theta, alpha, beta rhythms) consistent with consciousness and a possible resumption of a network-level of cognitive and neuronal activity emerged up to 35-60 minutes into CPR. This is the first report of biomarkers of consciousness during CA/CPR."

    I'd imagine there is pretty good evidence that after an hour of oxygen depravation, your brain might be recoverable, but it's also going to have a very high chance of being severely damaged at the higher function level.

    It also doesn't seem surprising that the effects of your brain progressively failing are not dissimilar to those from taking drugs that are designed to mess up the balance of brain systems.

        If CPR can be started as soon as a person's heart fails (i.e within seconds of a person falling to the ground) and it can be done correctly then a person's life can be saved and they won't suffer any loss of cognitive function. There are thousands of these people living their lives today thanks to pacemakers.

        The biggest obstacle they face in recovery is that part of their heart muscle dies, not brain damage. That can never be fixed unless the entire heart is replaced.

        Muscle is never repaired. If you're young enough you can grow new muscles in your limbs, but you can't ever sew muslces back together, nor do they "heal". They might stop bleeding but they don't join up together again.

          This. I have CPR certification, and the one instructor told me the same thing offline. They don't tell you in the classes, probably because they want people to believe they are doing something good for someone.

          It can even cause something called "CPR induced consiciousness", which is not a good thing at all.

          Oh shit. Oh shit. That has to be seriously traumatic for the person performing CPR, and any bystanders. Especially non-professionals. A somewhat conscious person that you might have to abandon the CPR. Damn, that's nightmare fuel.

        • Like many procedures in first aid, CPR is only a stopgap until more experienced personnel and/or equipment arrive. I feel the misconception about CPR is due to media portraying it as some sort of miracle procedure. That and defibrillators can magically bring back someone back from no heartbeats and death when all they do is shock a working heart back into a steady rhythm. If a heart has stopped, there is sometimes little a defibrillator can do.

      But once upon a time, diabetes was a effectively a death sentence. So were heart attacks.

    Nobody is brought back to life from death. By definition, death is a permanent state in which you cannot survive (or be resuscitated). 53 patients were brought back from near death. Yes, it might be very difficult to define exactly at what point "death" is and we might never be able to do so. It is especially difficult since our resuscitation ability moves with technological progress, but let's get real about reasonable wording choices. At a minimum, one could say "brought back from clinical death", but even that is pretty mushy.

      The notion of a "non-embodied mind" is an easy conclusion to jump to. It instantly resolves scientific questions about how the observed behaviors of subatomic particles could give rise to the phenomenon of "experience." (see: qualia [wikipedia.org] for greater clarity on what is meant here). It also neatly facilitates ideas of a possible afterlife (thus abating our instinctual fear of death).

      But all of these are reasons why we would prefer the existence of mind separate from body. Nothing here gives any kind of evidence.

      Our best observations of the world, collected over centuries of rigorous experimentation, show us nothing but matter and energy everywhere we look. It's physics all the way down! Furthermore, we have plenty of very strong evidence that all human behavior, including such acts as conversation, cognition, and perception, all happen right in the brain. Literally everything that is falsifiable points to this simple conclusion: the "mind" is what the brain does.

      But this does not mean that consciousness is somehow not real (as Daniel Dennett famously proposed with books full of specious reasoning). The humbling but inarguable fact is that our science is limited to what we can observe. These subatomic particles are so tiny that we can not observe them directly. We build specialized machines that allow us to see their effects, so we can make reasonable inferences about them. That's the best we can do. It's pretty good, but it leaves open the glaring fact that there may be more to these subatomic particles than we know. Our models of them are limited to what we can observe about them, and there is no reason to expect that we can observe everything there is to observe about them. There is every reason to believe that there is unexplored territory here, and possibly even unexplorable territory here.

      That does not mean that we have somehow gathered evidence that our ordinary experience of mind is the result of unobserved behavior of matter, but it does mean that such a hypothesis would be entirely consistent with physics, and would be more consistent with how literally everything else in the observed world works. (See Russelian Monism [stanford.edu] for some clarity on this idea).

      We gain an answer to the hard problem of consciousness [utm.edu] that is maximally compatible with the best science of our day, making smaller and more modest assumptions than any disembodied mind theory does. But we lose our popular conception of the afterlife. Under such a model, the destruction of the brain IS the destruction of the person. Consciousness ends when the brains ceases. Oh, how horrible! But there is a saving grace....the constituents of consciousness (that is to say, the particles involved) continue to exist (the atoms in the brain continue to exist after it has decayed, they just change form. Same with whatever electrons used to be zipping around in it, and so on. And therefore, same with the unobserved aspects of these particles that have consciousness-producing potential). Everything that we actually are continues to exist, it merely changes form, recombines into something new (and conscious) in the future.

      In short: we give up our notion of an immortal identity. But we gain an understanding of self that is consistent with science and experience (and, amusingly enough, consistent with Buddhist notions of "anatta" or "no-self").

      So, I consider the notion of a magical separate mind substance to be lazy philosophy. It's more convenient and more pandering to our emotions. But less consistent with everything we have learned.

      • Everything that we actually are continues to exist, it merely changes form, recombines into something new (and conscious) in the future.

        Consciousness takes place within Reality only through organized energy. When the physical particles involved in the organization of that energy are dissipated, unless there is a structure for the organized energy to go to, that organization of energy is lost. Which means you are no longer existing within this Reality.

        There could be higher realities... there might not be. Does it matter? All concerns from this Reality are washed away by Death.

      "episodes of heightened consciousness" - why "heightened"? What evidence of consciousness was even known?

  • Perform a double blind study in which an object may be in the room with the patient, and is not visible to the patient or anyone else in the room. In a basket tied to the ceiling for example. Set A has nothing. Set B has an object. Say a child's toy. The patient is told the basket may have something in it and if he has a near death experience where he can look around would he kindly look in the basket. Make it a proper double blind study, where even the guy who hangs up the basket doesn't know what's in it,

    All well and good that this gets researched, but to me it does not really sound like a surprise. When I was in middle school, I had a TI-34 calculator with a photovoltaic cell as a power source. One of my tricks when I got bored was to fill the display with 8's, "8888888888". Then cover the PV with my hand and saw the digits fading. If I removed my hand *just* right, I was able to get some funny patterns, some of which were not numbers at all - just random segments lighting up. If I kept the PV covered for too long, the calculator just reset. My guess is that the RAM got partially corrupted and resulted in that funky display.

    Really don't see that much of a difference. I've had a work colleague who got a blood clot in his brain - he noticed that suddenly he could not stand up from his chair. Well, he got better at the hospital where they dissolved the clot and all was well - but afterwards he told us that before they started treatment, he had started seeing some really psychedelic colors in the plain white hospital walls.

    So shouldn't come as a surprise that if you are getting massive damage to your brain cells (typically at the end of your life), then the experience is going to be somewhat weird.

    it's like when an old tv dies, and you can only see things from the snow dimension because it's locked into messages from a higher plane.

    Pathetic.
    • Subject: "New dimensions of reality"
      Oh look, a non-scientist incorrectly using scientific words in an attempt to appear scientific.

      You thought "dimensions" was an exclusively scientific jargon word? Maybe you should hold off on criticizing people's English until you learn a little more?

      And "reality" isn't a scientific word at all, it has no scientific meaning. When scientists use the word, it is only when trying to describe a hypothesis, theory, or experimental result using common language. A results supports the hypothesis, or it doesn't. "Reality" is meta-physics, not physics.

      • Dimensions as used here has a specific scientific meaning.

        The fact that your could not comprehend that suggests that it is best for you to stay out of this discussion and stick to the fluffy bullshitting you appear to enjoy.

  • in which some survivors of cardiac arrest described lucid death experiences that occurred while they were seemingly unconscious

    I have experiences all the time when I'm unconscious, it's called dreaming.

    Either way, were they unconscious? Seemingly brain dead? If so, what's the evidence they had experiences during these periods? I saw something in the abstract about giving them headphones so maybe there was some recall testing.

    The study authors hypothesize that the “flatlined,” dying brain removes

    • They have strong memories that are formed without brain activity.

      The idea that a brain creates consciousness is equivalent to the idea that a radio creates a newscast.

      From one perspective does it - but it's not the base reality.

      Giant advances in science always seem extremely odd to those most steeped in the art.

      Einstein didn't believe the Copenhagen Interpretation and it wasn't until 2015 that Bohm was shown to be mostly right. Still, even Bohm came to profess Copenhagen because his focus was slightly too

      • They have strong memories that are formed without brain activity.

        What's the evidence for that?

        The idea that a brain creates consciousness is equivalent to the idea that a radio creates a newscast.

        That's testable.

        By mucking with the radio can you change the content of the newscast? You can change the station, and you can lose quality of the newscast, but you can't actually change the content of the newscast.

        But by mucking with the brain you can significantly change the output of the consciousness. You can decrease the intelligence, you can change the personality, you can even induce behaviours.

        This is a huge way in which the brain is different from the radio, and is posit

      • The idea that a brain creates consciousness is equivalent to the idea that a radio creates a newscast.

        Close, but that doesn't really get to the problem.

        The idea that having a memory includes knowledge of when the memory is formed is equivalent to the idea that having a recording of a radio broadcast tells you when the broadcast happened.

        Ultimately, the memory might have been formed in a few microseconds as/after consciousness returned. There is no way to distinguish that using a subjective experience that doesn't include any sort of time-related metadata.

  • New dimension? Really? How do they infer that in anyway from EEG data and the recollection of a few survivors?
  • I interviewed quite a number of dead people at my local cemetery, and without exception 100% of them did not agree with the study's conclusions.

  • I've often wondered about this, the brain's last ditch effort to stay afloat like a drowning man, and then thought about time dilation in dreams. Who's to say that hour doesn't last nearly an eternity in the mind of the dying?

    So start thinking happy thoughts folks, because that's what you may get when you die. Cynics beware.

  • There's some unproven speculation about DMT being released on death but these reports are definitely consistent with what folks have said about psychedelic experiences.
  • Except the brain doesn't have a solution to the problem (of dying). So it tries to find a solution, which requires hallucination.

    That's what I think.

    I didn't read the article of course, but I did read the comments about it...

  • It's literally a DMT trip. New research suggests that it plays a function in protecting neurons from hypoxia. The near death experiences people describe sound exactly like the effects, they occur when the brain isn't receiving enough oxygen, and you see "new dimensions" during the trip in hyperbolic non-euclidian space.

  • Hallucinations of oxygen-starved neurons. Religious folk who almost died, usingvthose hallucinations to reassure themselves that there is an afterlife.
  • I am living proof that we can survive the brain going into hybernation for an hour: I've been through grade school, high school, and college classes.
  • Shut your nonsense holes. Near death experiences are caused by the brain essentially producing DMT as it struggles to maintain operation without oxygen: https://www.frontiersin.org/articles/10.3389/fpsyg.2018.01424/full. Thus the hallucinations. We've known this for years now. Your trippy hippy bullshit is irrelevant.

  • This won't convince anyone of anything, and I'll probably get down-modded to the ground for this, but I had an NDE (resuscitated, the whole nine yards) during a very traumatic surgery in the late 70's that I should not have survived. What I experienced was unlike anything else in my life before, or after.
