Wow. That must have been some IRB meeting.
> In animals, complete global ischemia causes complete electrical inactivity (ie, isoelectricity) of affected gray matter within about 20 to 40 seconds. This cerebral silencing is regarded as an austerity program to curb neuronal energy usage by the shutdown of nonessential cell functions well before the neuronal adenosine triphosphate (ATP) pool is depleted and prospects of tissue recovery vanish. [...]
> Despite this austerity program, sodium and calcium always leak into cells and potassium leaks out. [...] When a threshold level of failure, usually reached 1 to 5 minutes after nonspreading depression, has rendered the ischemic tissue isoelectric, neurons then undergo abrupt, nonlinear rundown in the ion gradients across the cellular membranes. This depolarization develops en masse from either one or multiple foci and spreads in the tissue as a self-propagating wave.
Attempted TLDR: Not enough fresh blood and neurons go into a crisis mode to stay alive. However, they keep leaking electrically-important stuff, and once past a point there's a fast-spreading wave of doom through the neuron that really kills it.
that should generate a [miniscule] EM wave.
>This depolarization develops en masse from either one or multiple foci and spreads in the tissue as a self-propagating wave.
so a very sensitive EM detector should see a burst of EM radiation. One can wonder whether some [very sensitive to EM] people may perceive that as "departing soul" (and technically that burst of radiation does have the imprint of the neuronal configuration which generated it). Also one can wonder (well it can be calculated/measured i suppose) whether that burst of EM radiation can cause some electrostatic effects and or some kind of luminescence around the body in say very dry air or the air with very fine dust or in presence of some non-typical gases or liquid drops suspended in the air.
What sort of people are those? Are we talking about "psychics?"
People have various ranges of abilities/sensitivities and i just theoretically allow for outliers like one or two orders of magnitude difference for some people (or a mutation producing for example something along the lines of that magnetic field vision that birds have (some molecule in their eyes acting like a compass))
Saying that a human could do the same from a distance is magic masquerading as pseudoscience.
Could any experts comment and inform if such a thing is inside the realm of possibility as we know it?
