A dilemna. We have no knowledge of energy transmission sites in the brain yet clinically dead people, if the Doc's study is to be believed, are describing events that occur when they are clinically dead.So how can this be? Well, one could explain auditory and tactile inputs by positing that we can't measure electrical activity in the brain at the levels it is happening during shutdown. But how does one explain the visuals? Dead people can't see through their eyelids and eyelids are closed when patients shutdown for a reason.
Is this science?
My default position is to be skeptical (the 'show me' attitude). People are often able to give quite detailed descriptions of events and circumstances based on purely auditory access to those events and circumstances. Plus I'd like to know how many of the near-death events took place in standard operating rooms (we all have a pretty good idea of what such places look like), and whether the patients were at any time able to see their surroundings, either before they flat-lined or after they were revived. One can well imagine that even brief glimpses of one's surroundings in such emotionally charged circumstances could make deep and lasting impressions. And so on...
But, of course, there's likely to always be a residual few cases that resist explanation, just as even today there are probably a few residual UFO cases that resist explanation. But anecdotal, odd-lot incidents are not the best foundation on which to erect a theory of consciousness and a theory of reality, it seems to me.
I could be mistaken, of course...
A good answer.
