It nicely explains the fact that people of different faiths who have near death experiences get visions of the gods they believe in -- their brains create the illusion of what they expect to see.
Nothing terribly suprising.
Why does the brain 'bother' to generate a long, light-filled white tunnel, meetings with dead relatives, out-of-body ability to see from the ceiling what isn't visible from the operating table or bed ?
From a scientific point of view, none of this is necessary, so how does science explain the brain's need to do this ? In actual fact, no one knows, nor can they ever know for sure.
I've heard of people that after they where reccuitated said things like, I was looking down at myself from the ceiling etc. I could see Dr X was pressing down on my chest etc. Now the first question is this an illusion? There is a scientific study going on right now, that is looking at over 30 medical centers around the world, with some of the leading experts on resuscitation, neuroscience, emergency medicine, to try and find out what has really happened when someone has died. It's called the Aware study and they're recruiting over 1500 patients who've clinically died and been brought back to life again, and the study is very broad and they look at various aspects of resuscitation but the part that is relevant here is the claims that people have been conscious when they've in fact died. So what they do, they place some kind of image that is only visible from the ceiling, so the theory being that if in the operating room if you have 500 people who amazingly come back and tell amazing stories, if it's just a trick of the mind then none of them should be able to see the pictures, so if no one sees the pictures they can conclude that it must be some kind of illusion.
You say the way I described this, people have died, there is a flat line state in the brain, there is no brain activity, people claim, and I don't say they're right or wrong, now the people claim they can see their doctors, and they describe incredible details, it's possible it's an illusion but they need to test it more and that's why studies such as the Aware' are important.
