Neurons do some thing unusual whilst starved of oxygen. First, they start firing randomly. Then they begin to shut down. If they do not acquire treasured oh-two quickly, they begin to die.
This collection is, of path, an oversimplification. You’ll discover counter examples all over the region.
Even so, this series explains loads.
When certain components of the mind (the temporal lobe and some others) start misfiring, you get hold of a flood of memories. This can range from an unusual montage of random activities to full-blown hallucinations.
When the entire brain starts offevolved firing randomly, it’s a seizure. But whilst elements of it set off for no reason, it is able to create predictable consequences. For example, inside the occipital lobe, this will result in seeing a spinning vortex of light. It’s dark round the edges, probably due to the fact peripheral imaginative and prescient shuts down first.
Even your feel of balance can do bizarre matters. The misfires followed with the aid of a shutdown can create the feel that every path is the same.
And if the left mind weakens first (or the proper mind starts misfiring greater intensely), then you acquire an first-rate experience of peace, expertise and connection to the universe. Even as your focus fades.
When situations are right, you get a feel of floating, hallucinations, your life flashing before your eyes and the ‘mild-at-the-cease-of-the-tunnel’ effect.
And there you’ve got it: a manageable, mundane reason behind near demise studies.
Is this model correct?
I do not know.
It’s probable lacking some information.
But, if it is in the right course, it explains one of the maximum religious stories humans have with out assuming that people have souls. This works, even though we are no more than squishy meat computer systems.
Don’t suppose I’m doing this because I’m a merciless, mirthless stereotype of a rationalist. The moral isn’t always that, having defined it, the experience is meaningless.
No – the moral is that our brains are brilliant.
If you need to revel in any of these consequences, you don’t want to nearly die on a doctor’s desk. The brain can create any of those stories at any time.
