Two minutes of Googling gave me this paper from 1994, which reports that in various studies:To have an OBE, to see the tunnel, then the light, then the words: 'it's not your time yet' assumes a certain patern of electric activity in the brain.
It must be a big coincidence that the dying brains of all these people are functioning so well that they have the same sequence and patern of electric activity.
Yes, but 'the light', 'the OBE', the tunnel and the lifereview are very common.
I disagree here. Most NDE's are very specific. The OBE, the tunnel, the light, the words: it's not your time yet. That's very specific.
The words "it is not your time yet" is probably a cultural thing: these people know what is expected for an NDE will tend to remember exactly that.
I don't know. That can be the case, but I'm not convinced.
I recommand you to listen to the testimonies of many NDE'ers on Youtube.
Sadly, after the study, the authors published cherry picked results ignoring the most important (or only real) evidence.This is a prospective study of cardiac arrest patients to not only describe their NDEs when they occur, but to conduct a large prospective test looking for objective evidence of conscious awareness during resuscitation. The lead researcher, Sam Parnia, is a believer in NDEs, but designed a study theoretically capable of finding objective evidence.
The multi-center study involved placing an image in a location that was hidden from normal view but could be viewed by a person floating above their body during an NDE. This could be a way to objectively differentiate between the two leading hypotheses. Parnia and others believe that reports of NDEs represent actual awareness during cardiac arrest when the brain is not functioning. This, of course, would be compelling evidence for cognition separate from brain function. ...
... Well that’s disappointing. However, apparently there were no cases of cardiac arrest patients who were able to see, remember, and report the hidden images. Collecting data was more difficult than they hoped, but the results they did get were negative.
Failing to obtain any actual evidence that NDEs represent non-corporeal cognition, Parnia apparently decided to fall back on the old, let’s just report what people say and present that as if it were actual objective evidence.

It's the perception of cerebral hypoxia (if that qualifies as a perception; perhaps 'experience' is more apt).I don't think it proves that the NDE is just a delusion. The brain activity in these experiments indicates the perception of something.
I don't know. That can be the case, but I'm not convinced.
When you are unconscious, you cannot report having a NDE.
Why not a very elaborate jewel and precious metal encrusted bridge with lasers and flashing strobes or those super bright LED flashlights and a neon sign a thousand feet high flashing "HEAVEN"?
A very perceptive comment! It's all post hoc — spoken in words which spring from the soil of culture, fruiting phrases sown deep in our minds by memory we had no will but to form.
To speak, perchance to Recall; Aye, there's the hubbub,
For in that sleep of near death, what memes may come,
When we haven't utterly shuffled off this mortal coil,
Must give us applause.

Even if they did indeed flat line for a period there was brain activity before and after that period. There is no reason to assume any experiences they later relate occurred during the flatline period rather than before or after it. Claims of experiencing externally verifable occurrences during the flat line period never stand up to investigation, and experiments attempting to obtain objective evidence of such claims have had negative results.I'm curious about NDE's myself, always have been since I heard the story when I was a kid about my grandfather having one when the Spanish flu almost killed him back in 1919 or so.
So, what's the skeptical explanation for the fact that people who have these often do so when their brain wave activity has flatlined, especially those who describe externally verifiable occurrences during that time? Seems to me it's hard to explain this phenomenon in terms of anomalous brain activity when there isn't any such activity going on.
You don't know that. Not all NDEs proceed according to your idealized model.Other argument: these experiences are not chaotic at all,
Who's this "you", kemosabe? Can you cite where the expectations of an injured, dying brain have been established?what you expect from an injuried dying brain.
Bald assertion with no basis whatsoever.A dying brain cannot produce such harmonious experiences full of meaning and very vividly.
Bald assertion with no basis whatsoever.It's a contradicition.
Bald assertion with no basis whatsoever.A good working brain can produce these beautiful experiences. But not a dying damaged brain.
Again with the "you" stuff. Who is "you? Can I suggest that you either speak for yourself or cite sources for more general assertions.From a dying brain you expect chaotic hallucinations.
