I already posted what I think about your "scientific studies".
At best, they could be anecdotal cases suggesting the surviving and limited function of the neurons for some time more even without blood flow.
Your estimate of the scientific study called AWARE is founded in ignorance, because
1) the AWARE study under discussion presents a
documented case (a clinical patient) which suggests the hypothesis that consciousness persists without the possibility of
brain function (this is the same as saying that the two are independent), and
2) such a case would be very easy to replicate, in fact AWARE 2 is in the works! Only two out of the 152 patients reported any visual experiences, and one of them described events that could be verified, but according to you even a verified visual experience is fictional
if it suggests that mind and brain can function independently. You never even said that these studies would be more interesting or acceptable if there were more controls, more replications, more patients with OBEs, & etc.
Your statement suggests to the reader that
brain function during this time-frame is possible without blood flow, but YOU HAVE NO EVIDENCE OF THAT! In fact, shock or the lack of perfusion of oxygen to the brain is very common in many medical situations but
is not associated with NDE-like experience at all.
Even skeptic Chris French admitted that validating the formation of perception and memory during such a time-frame would suggest that consciousness is not being generated by the brain.
Only believers (that want to believe no matter what) see these cases as evidence of a "soul".
Like it or not, the case was validated by eyewitnesses, and it is not the first case of its kind; on the other hand, science has yet to find and similarly demonstrate a case of brain function under anoxia after a certain brief period of about 40 seconds. It is dishonest for you to ignore that
you also have a burden of proof in this discussion; you accepted the materialist explanation thinking that it was scientific, now I am informing you that it is not based on any evidence. The materialist scientists have not provided any evidence of brain function as you are suggesting, so failing that possibility, what is your burden?
All scientists have to do is figure out how the brain tricks the individual into believing that something fake is real. Of course all this is an article of faith which is, in principle, not very different from the faith claims made by religious people. However, with these kinds of assumptions, is it any wonder why scientists are not considered objective explorers of the world? They lose their objectivity when they become materialists of the fundamentalist variety who cannot imagine seeing the world outside of this limited, pragmatic, physical frame of reference.
