Are you aware that the electromagnectic field generated by the brain is 9 to 12 orders of magnitude weaker than the ambient magnectic field, i.e. Earth's magnectic field? As stated in my previous post it requires special amplifying equipment to even detect.

The behavioral response observed was apparently due to the mice's temporary exposure to a hypo magnetic field.
We shall not cease from exploration
And the end of all our exploring 
Will be to arrive where we started
And know the place for the first time.

At the same time a rat skull is significantly thinner than a human skull. Also the article you are referring is using time frame of several hours of change in electomagnectic energy exposure to detect an effect compared to the 'instant' effect when people have a NDE during cardiac arrest.

Look, there's no link here to your NDE theory. Why not just propose some magic energy carrier rather than electomagnatic energy?

The magnetic component of the EM field is relatively unaffected by passing through the thickness of the scull, unlike the electric component.

We don't have a mechanism yet for these magneto-biological effects, but researchers are looking at things like the magnetic moment, angular momentum, and a wide range of other possible candidate theories.

The magnetic fields produced by neuronal activity in the brain are on the order of a few femtoteslas (fT) to a few hundred femtoteslas. For context, 1 femtotesla is 10E-15. To put this in perspective, the magnetic field of the Earth is much stronger, roughly around 25 to 65 microteslas (10E-6).

If magnetism affected consciousness to the degree you are proposing it would be obvious for example for astronauts in LEO.

Behavioural effects in organisms at hyper-weak magnetic field strengths, which can be thousands of times weaker than the local geomagnetic field, are well documented in the field of Magnetoreception.

And, I've already referenced a paper showing robust behavioral effects in mice temporarily exposed to a hypo magnetic field.

The experiment was "1 h per day for 10 consecutive days" with the maximum analgesic effect being at 4-6 days. There might be a connection with NDEs but I'm not personally convinced.

Nearly every electrical apparatus emits weak magnetic fields. We are exposed to a vast array of different electromagnetic sources every day, many of which are very weak, without any proven effect on human consciousness. It's worth noting that humans are not rats. Moreover, NDEs occur 'instantly,' not after an hour per day for ten consecutive days.

I must say that I don't give much scientific credence to your NDE theory, especially the broad extrapolations you're drawing from a rat study. However, I'm pleased for you if you are personally satisfied with your interpretation of the NDE 'enigma'.

This, of course, is to Max_B.  It looks like you are saying it to me in your post.

The researchers had observed the same effect in mice after a single exposure to a hypo magnetic shielded environment in a previous study. This was a follow-up study. Obviously rats can't tell us about their experiences, so we rely on observing their behaviour. In humans, behavioral changes from NDE's have been found in experients for months and and years following their experience.

There is actually plenty of published literature on effects of magnetic fields in humans, but it tends not to be replicated, and/or has reproducibility issues which plague the field. More recent experiments under hypo magnetic conditions, which attempt to control for the magnetic field appear to be more successful in their reproducibility within the field of magneto-biology more generally, but it's difficult to undertake such research with humans for practical and I guess ethical reasons.

Another reason I'd guess research is lacking, is obtaining funding for such research. Because of the financial importance of electromagnetic field generating technology to society, going fishing for such effects in humans is probably not a high priority. But research is there, an example at picoTesla strengths... https://scholar.google.com/scholar?hl=en...netic&btnG=

Contributing this source that refutes a lot of the supposed materialist “explanations” for NDEs
