The digression into mysticism in this thread is weird. Finding a physical correlate of NDEs reinforces the materialist view, which is basically the null hypothesis for "sceptics". Everyone who didn't already believe in an immaterial soul can calm down.
What is "materiality"? Electrons guided by magnetic field that form one universal wave function? In that case even the hardcore materialists are fundamentally in agreement with mysticism.
No they aren't, despite the superficial similarity, and I think you know it. At best you haven't actually thought about the difference between a measurable field defined by math and a mystical "field" ultimately defined by feelings.
"Mysticism" is a belief that everything and everyone are different manifestations of the one (law, origin, something that's beyond words and imagination). Science is a belief that there is one universal law of nature and that everything is its different manifestations.
