Here's an article showing how the facts in the article were not accurate.... that Luke Dittrich's facts were twisted and inaccurate ... and that Dr Alexander's can be corroborated with facts...

http://iands.org/ndes/more-info/nde...cle-on-eben-alexander-distorts-the-facts.html

Biased website is biased.

Like I said. If you chose to accept that this guy is on the up and up, be my guest.

Even wiki has something on this guy.

https://en.m.wikipedia.org/wiki/Eben_Alexander_(author)

He changed medical records, lies about a coma being the same as brain death, says the coma was not medically induced.

This is not the behaviour of an honest fellow.

Your article wasn't a biased website? And WIKI as a credible source? You have got to be kidding. Siting Wiki as a source even in a basic level college class is cause for the documentation to be doubted and the the paper to be downgraded.
Actually, if you read my article (like I did read yours because I do like to look for real evidence), you would find out the details of that coma. Dr Potter is the one Dittrich quoted and she was very upset after he published because he twisted what she said. The details of his coma are published in an appendix of Alexander's book. And I doubt that he said a coma was the same as being brain dead because that simply isn't true...and even a student nurse would know that. I don't think you know what you are talking about and yet want to argue based on biased information from a single uncredible source because you simply don't like what he said.

Yup, such hyper-vivid personal experiences can be life-changing; but that doesn't mean they're real. I heard an interesting discussion on BBC Radio 4, where a neurologist specialising in drugs and neurotransmitters compared Dr Eben's description of his experiences with a couple of descriptions of ketamine trips from his patients; they were strikingly similar in imagery and emotional response. This isn't to say Dr. Eben was given ketamine, only to emphasise that such experiences can be induced without an NDE. A more sober (!) analysis appeared in Scientific American; you can find other critiques online, but avoid Esquire's piece of poor journalism.

This is not a simple drug trip. The brain of someone during a nde isn't experiencing the same things as the brain of somone going through a drug trip, even if someone who is really high can say such things. For example, here is one person who died for an hour and a half. The brain and body were cooled so that they were not functioning, during surgery, then brought back. This person remained conscious and wasn't affected by the anesthesia as well. So there was no chemical affect in the brain because it was SHUT DOWN.
There is no similarity whatsoever between a drug trip and a NDE, sorry, unless you take the tales of someone who is really high as evidence, they can say whatever they want it is there drug fueled imagination that is doing it. I am talking about people that have been clinically dead with no brain activity.

There is a book written by Trudy Harris called Glimpses of Heaven where she records hers and other hospice nurses' experiences with patients as they are dying. Not necessary the same but these people didn't come back. They actually died and stayed that way. These are simply observations as they help their patients die. Many patients when getting close to death talk to family members who have already died like they are in the room. Many children report an angel like being coming to get them but the child turns them away for several days because the parent isn't ready to let them go yet. This also goes for adults and part of normal hospice nursing is helping the family to let them go because it is known that patients sometimes hang on for a very long time if a close family member isn't ready to say good-bye.

Again, not proof because there can't be any...but solid evidence that something may be waiting on the other side.

IMO, it is evidence that when the brain starts to become deprived of oxygen, people can experience unusual experiences.

I have trouble believing that near-death experiences are similar to ketamine trips.

I had an accidental and brief ketamine trip during a medical procedure. I was left with panic attacks for weeks. Especially riding in cars and seeing anything moving.

This is not a simple drug trip.
That's what I said - you quoted me saying that.

The brain of someone during a nde isn't experiencing the same things as the brain of somone going through a drug trip, even if someone who is really high can say such things.
There's no way to know that, but no two brains are the same, so it seems a reasonable assumption they're not identical - but there can be similarities.

For example, here is one person who died for an hour and a half. The brain and body were cooled so that they were not functioning, during surgery, then brought back. This person remained conscious and wasn't affected by the anesthesia as well.
In the video he says he went to sleep at first, then became conscious but paralysed as the operation started - as I said could happen. But then "Everything went black..." and he started having his hyper-vivid experience - including the same extreme emotional responses as have been reported in other cases of brains recovering activity after 'shutdown' and similar to reports during drug-induced experiences. For the duration of inactivity, there will be no consciousness, no sense of the passage of time; when brain function resumes, experience resumes as if uninterrupted. I've already described how a seemingly lengthy experience may be produced in a relatively short time.

There is no similarity whatsoever between a drug trip and a NDE, sorry, unless you take the tales of someone who is really high as evidence, they can say whatever they want it is there drug fueled imagination that is doing it.
You can say that, but however much you dislike the idea, the some reports are are similar in key respects, that points to unusual activity in common areas of the brain. If you don't want to accept the reported experiences from controlled experiments with psychedelics, what makes you think reports of experiences from people suffering existential trauma are likely to be more reliable?

Don't forget that drugs like ecstasy and psychedelics function by either mimicking the brain's neurotransmitters or triggering the release of a surge of those neurotransmitters (dopamine, serotonin, vasopressin, oxytocin, endogenous opioids, etc.); if an excitable brain releases a surge of those neurotransmitters as it recovers from some physiological trauma or deep anaesthesia, the patient may have similar experiences.

I recommend you read more around this fascinating subject - Huxley's classic, 'The Doors of Perception', McKenna's 'True Hallucinations', Shulgin's 'PIHKAL', Oliver Sacks' 'Hallucinations', Stanislas Dehaene's 'Consciousness and the Brain', and others.

I am talking about people that have been clinically dead with no brain activity.
Clinically dead means no detectable activity. But that doesn't matter, we can assume the neurons are quiescent; the reports are consistent with a surge of unusual activity as the brain recovers function.

By all means believe in life after death, free-roaming consciousness, magical realms, etc., but these reports are also consistent with a neurological explanation, and if you directly stimulate the relevant specific brain areas, you can elicit every component of these experiences, from the overwhelming sense of love, a sense of hidden presence, voices, fantastical visions, expanded consciousness, dissolution of self, etc.

Just sayin'.

Such experiences are very variable; in the heyday of psychedelics in the '60s & '70s, they were crudely divided into 'good trips' and 'bad trips', but the depth and quality of such experiences are contingent on the person, dose, purity, context, mood, etc. Either way, they can be life-changing experiences - not to be taken lightly.

How would a skeptic explain a near-death experience of a person who has been blind from birth and has no idea what it is like to see, having an experience of sight?

I have real trouble understanding how the "dying brain" hypothesis fits with that.

I agree that if near-death experiences are true, it might present problems for fundamentalist interpretations of Christianity. But I don't see how it necessarily must overthrow Christian faith itself.

Hardly solid - it's anecdotal evidence of the activity of a dying brain.

as close as we are going to get at this point in our ability to research thoughts...what kind of evidence do you want? this is the type that is used in psychiatry medicine all the time because we can't measure thoughts or read minds...

EEGs, MRIs, CT, PetScans, and all the rest can't measure thoughts or even the presence of thoughts....even the EEG, which is as close as you are going to get, only measures brain activity...not thoughts... so we are left with observational studies like the observations of nurses, doctors, social workers, therapists, and so on....

so yes, I said solid EVIDENCE (def=the available body of facts or information indicating whether a belief or proposition is true or valid) and this is evidence even if it is not proof....the observations of nurses has always been considered evidence in a medical record...

In medicine we study the signs and symptoms of a patient...signs being the things that anyone (quite often the nurse and doctor) in the room can observe and symptoms being things that only the patient can report (pain, fatigue)....so these anecdotal incidences can be considered the signs and symptoms related to a dying patient and indicate the dying brain believes it is going toward a life beyond our life. Again, this is the best we are going to do on the technology we have today.

Solid evidence? ;)

Seriously though, the lack of evidence and the difficulty of collecting evidence is a major problem. NDEs and OBEs are rare and unpredictable, so it's hard to study them by preparing for them (as the AWARE study showed). Which raises a related point - why aren't they far more frequent in such patients if they really are glimpses of the afterlife?

Solid evidence would be along the lines of someone obtaining novel information during such an experience that could be precisely verified and which could not have been known beforehand - again, very difficult to evaluate, but it hasn't happened; why not?

If we are to simply accept uncorroborated and unsupported first-hand reports of extraordinary personal experiences as veridical (or probably veridical), we must accept all such reports claimed to be real as probably veridical - alien abductions, 'psychic' dreams, hallucinations, Third Man syndrome, drug trips, OBEs, etc. 'Delusion' would become obsolete... unless there is some particular reason why NDEs should get special consideration?

..this is the type that is used in psychiatry medicine all the time because we can't measure thoughts or read minds...
Psychiatry is aimed at mental, emotional and behavioral disorders, so the patient's state of mind and mental experience is highly relevant; scans, blood tests, and other evaluations can help determine if there are any abnormal somatic contributions.

EEGs, MRIs, CT, PetScans, and all the rest can't measure thoughts or even the presence of thoughts....even the EEG, which is as close as you are going to get, only measures brain activity...not thoughts...
Not strictly the case now - EEG is a lot more sophisticated than it used to be, but MEG (magnetoencephalography), which has been around since the '60s, is even better, and just as simple (if not so portable) to use. MEG can measure the neuromagetic signals from the firing of neurons to a resolution of 50,000 to 100,000 neurons at millisecond timescales. It complements fMRI scanning, which tracks activity by blood flow, allowing millisecond resolution of activity across the brain. So it's now possible to describe the neural correlates of consciousness as patterns of brain activation (i.e. global rather than local), detect the fuzzy mapping of objects (e.g. letters) in the visual cortex, and (crudely) recognise when someone is thinking a particular thought or about a particular activity by identifying the pattern of activation associated with it. This has allowed researchers to detect and communicate with a few patients with super-locked-in syndrome that are conscious, and to show that up to a third of 'minimally conscious' patients probably aren't conscious. Using this data, they're now developing algorithms for EEG analysis that may be able to do this at the bedside.

... these anecdotal incidences can be considered the signs and symptoms related to a dying patient and indicate the dying brain believes it is going toward a life beyond our life.
Sure, I wouldn't argue otherwise - but a belief is just a belief. If a belief was a reliable indicator of truth, we'd all be right almost all the time, and that is not what we see in the world.

It's hard to say without more information - exactly what have they reported? are their NDE descriptions qualitatively different from their descriptions of the everyday world?

It's been shown relatively recently (in the sighted) that when visual input is blocked for long periods (a week or two) and a novel sensory input is provided (e.g. a haptic sensor), the visual cortex is eventually recruited to process the signal, giving a pseudo-visual experience of that sense. This is also the case in people who are congenitally blind due to sensory deficit but who have an intact visual cortex. Their visual cortex is active, although they don't seem to dream visually, but they may have a limited visual perception by 'leakage' of their other senses into the visual cortex... but I'm guessing here, just a leap in the dark(!). I'd want to know more about these people and what they reported. It's an interesting area of research.

Me neither.

Done with this thread but need to clarify, psychiatry is the study of the mind...both healthy and disorders. Same as medicine is also concerned with the well-body and maintaining it.

I would say a dying brain is a not a healthy one. However, I still believe the conscious continues to exist beyond the body. That is both my belief and my experience with death up close and personal.

Yes. Many who have never had sight say they could see for the first time. They don't typically describe color but that's understandable since color description is learned through acculturated experience.

Another thing to consider is many people who have their sight restored medically seem to fare poorly, in some cases it can cause mental health problems trying to integrate the new stimuli. That doesn't seem to happen whith the blind NDE experiencer, there isn't a problem integrating the new stimuli in the experience itself.

But how would they know if they've never seen before? I can't think of any reliable way to tell - can you? (seriously).

... many people who have their sight restored medically seem to fare poorly, in some cases it can cause mental health problems trying to integrate the new stimuli. That doesn't seem to happen whith the blind NDE experiencer, there isn't a problem integrating the new stimuli in the experience itself.
This could be taken as suggesting that the blind NDE experience isn't like real sight, but how they imagine sight to be. If there is no visual sensory input at all during development, certain parts of the visual cortex won't develop fully and the chance of normal vision is low, even if full visual input is made available; the visual cortex is recruited to help the other senses, and there's only a limited amount of flexibility in the system. If there is residual vision, e.g. light/dark discrimination, as in many cases of blindness, visual cortex development is likely to be more developed.

The most common NDE feature, the tunnel with a bright light accompanied by a powerful sense of love and wholeness, etc., is consistent with a failing brain - there are various causes of tunnel vision, and the intense positive emotional experience is what you'd expect from the uncontrolled release of neurotransmitters & hormones such as dopamine, serotonin, vasopressin, oxytocin, and endogenous opioids. I'm surprised by the article's assertion that a concept of hell is more widespread than one of heaven, but the neurotransmitters & hormones would explain why the experience is generally positive.

The whole gamut of NDE experience is not fully understood, or even well understood, from a neurological perspective, but there are sufficient correlations and similarities with other experiences to suggest that there is nothing inexplicable about it.
