Sriram loves to bring up the subject of NDEs and OBEs from time to time. As always, he sees the existence of NDEs as some sort of evidence that consciousness is something which has an existence outside the brain, and that it points to some sort of afterlife. As always, he never provides new evidence that his pet theories are any more correct than previously. As always, I suggest, he never seriously considers alternative explanations.
Take his reference to Sam Parnia, for instance. He is quite correct in saying that Parnia sees these as after death experiences, What he doesn't tell you is that Parnia himself suggests that our definition of death has changed with the increasing medical understanding and technology at our disposal, and that he sees it as a process rather than an exact event. Parnia has also suggested that:
The evidence thus far suggests that in the first few minutes after death, consciousness is not annihilated.
A person who has experienced a genuine NDE, has gone through three main stages:
1) Moving from a conscious state to an unconscious state. During this state there is definite brain activity.
2) Unconsciousness, which may include a period when brain activity flatlines
3) Moving from an unconscious state to a conscious state. During this state there is definite brain activity.
This whole event is a process, and there is no evidence that NDEs are only a phenomenon related to No 2.
My position on the idea that NDEs are not a function of the brain/mind is as follows:
1) There would have to be convincing evidence that either a)the brain plays little or no part in the whole NDE experience or b) the brain is simply the receiver of the NDE experiences.
2) It could be demonstrated exactly where, when and how the 'afterlife' world communicates with the physical body.
3) Experimental evidence would be produced which demonstrates such communication, and which is capable of falsification.
4) There would have to be objective, clear and convincing evidence of identical NDE experiences as the norm.
In response to these:
a) I have seen no evidence whatsoever that confirms No 1.
b) I have seen no evidence whatsoever that confirms no 2.
c) Any attempts at no 3 have so far produced negative or inclusive results. However this area, I believe, would benefit from more widespread and co-ordinated testing.
d) There is a large body of evidence which clearly suggests that such experiences are not at all identical. Even general traits, such as out of body experiences or feelings of peace, seem to be dependent on cultural influences. Out of 11 non western studies, involving 7 countries, only China and Japan seemed to show feelings of peace during an NDE. OBEs were absent from studies in Zambia and the Congo, and in only one of 55 reports from India. I would accept, however, that this area would greatly benefit from further data.
So what about actual scientific tests to establish whether anyone having an OBE can actually see something which would be hidden from view unless the person was having a floating OBE. To my knowledge there have been at least 5 totally blind tests(no living person would know the content of the visual target) from 1990 to 2006, all of them in recognized hospitals. None have resulted in anything but negative data so far. Since then Sam Parnia has conducted such tests in his famous Aware 2 Study, again with negative results.
I think the most damning statement on this so important subject of veridical evidence is contained in this email from 2006, by an eminent NDE researcher, Kenneth Ring, who was discussing this with Bruce Greyson:
There is so much anecdotal evidence that suggests (experiencers) can, at least sometime, perceive veridically during their NDEs.....but isn't it true that in all this time, there hasn't been a single case of a veridical perception reported by an NDEr under controlled conditions? I mean, thirty years later, it's still a null class(as far as I know). Yes, excuses, excuses--I know. But, really, wouldn't you have suspected more than a few such cases at least by now?....
To sum up.
I agree that NDEs happen.
I would welcome further scientific research in this area.
I see no evidence that they are linked to the idea of an 'afterlife' or non-local consciousness.
I am very willing to adjust my position in the light of objective and extensive scientific research.
