From wired.com:
"Sam Parnia practices resuscitation medine. In other words, he helps bring people back from the dead — and some return with stories. Their tales could help save lives, and even challenge traditional scientific ideas about the nature of consciousness.And:
“The evidence we have so far is that human consciousness does not become annihilated,” said Parnia, a doctor at Stony Brook University Hospital and director of the school’s resuscitation research program. “It continues for a few hours after death, albeit in a hibernated state we cannot see from the outside.”
"Parnia: I decided that we should study what people have experienced when they’ve gone beyond cardiac arrest. I found that 10 percent of patients who survived cardiac arrests report these incredible accounts of seeing things.
When I looked at the cardiac arrest literature, it became clear that it’s after the heart stops and blood flow into the brain ceases. There’s no blood flow into the brain, no activity, about 10 seconds after the heart stops. When doctors start to do CPR, they still can’t get enough blood into the brain. It remains flatlined. That’s the physiology of people who’ve died or are receiving CPR.
Not just my study, but four others, all demonstrated the same thing: People have memories and recollections. Combined with anecdotal reports from all over the world, from people who see things accurately and remember them, it suggests this needs to be studied in more detail."
And,
"Wired: Couldn’t the experiences just reflect some extremely subtle type of brain activity?
Parnia: When you die, there’s no blood flow going into your brain. If it goes below a certain level, you can’t have electrical activity. It takes a lot of imagination to think there’s somehow a hidden area of your brain that comes into action when everything else isn’t working.
These observations raise a question about our current concept of how brain and mind interact. The historical idea is that electrochemical processes in the brain lead to consciousness. That may no longer be correct, because we can demonstrate that those processes don’t go on after death.
There may be something in the brain we haven’t discovered that accounts for consciousness, or it may be that consciousness is a separate entity from the brain.
Wired: This seems to verge on supernatural explanations of consciousness.
Parnia: Throughout history, we try to explain things the best we can with the tools of science. But most open-minded and objective scientists recognize that we have limitations. Just because something is inexplicable with our current science doesn’t make it superstitious or wrong. When people discovered electromagnetism, forces that couldn’t then be seen or measured, a lot of scientists made fun of it.
Scientists have come to believe that the self is brain cell processes, but there’s never been an experiment to show how cells in the brain could possibly lead to human thought. If you look at a brain cell under a microscope, and I tell you, “this brain cell thinks I’m hungry,” that’s impossible.
It could be that, like electromagnetism, the human psyche and consciousness are a very subtle type of force that interacts with the brain, but are not necessarily produced by the brain. The jury is still out.
Wired: But what about all the fMRI brain imaging studies of thoughts and feelings? Or experiments in which scientists can tell what someone is seeing, or what they’re dreaming, by looking at brain activity?
Parnia: All the evidence we have shows an association between certain parts of the brain and certain mental processes. But it’s a chicken and egg question: Does cellular activity produce the mind, or does the mind produce cellular activity?
Some people have tried to conclude that what we observe indicates that cells produce thought: here’s a picture of depression, here’s a picture of happiness. But this is simply an association, not a causation. If you accept that theory, there should be no reports of people hearing or seeing things after activity in their brain has stopped. If people can have consciousness, maybe that raises the possibility that our theories are premature."
Parnia should be prepared to be called all sorts of things, probably including but not limited to "fraud", "incompetent", and other attacks on his person by those who cannot attack his data. That's what happened last year to the professor from Texas A&M who had the bad judgment to study the effect of having homosexual parents on children (he was exonerated after an investigation of his techniques and conclusions by the university showed the actual integrity of his work).

Prof was from UT Austin. But your point is correct.
Hello,
These types of replicated studies show again and again, that paradigms in the way science is seen, need to change. But that's a political issue altogether, rather than the metaphysical claims (made in the name of metaphysical naturalism or not) in relation with the application of the scientific method, by themselves (but that issue is also very important). Thomas S. Kuhn explains it quite well.
Just please, do not tell skeptoid's people about it, they might get mad! and explain to us, with their typical hubris, "how science should be done" :)
While debating with radical skeptics, it is strongly advised, to be careful with the words to be chosen. Emotional sparks may arise.
Kind Regards!!
Stan, you might be interested in the research by Penrose and Hammeroff cited here:
It is based on a quantum theory of consciousness [Hameroff] and British physicist Sir Roger Penrose have developed which holds that the essence of our soul is contained inside structures called microtubules within brain cells.
They have argued that our experience of consciousness is the result of quantum gravity effects in these microtubules, a theory which they dubbed orchestrated objective reduction (Orch-OR).
Thus it is held that our souls are more than the interaction of neurons in the brain. They are in fact constructed from the very fabric of the universe – and may have existed since the beginning of time.
