It was a world view shattering insight for me that consciousness can exist independently of a functioning brain. This is becoming more widely accepted now.
“First hint of ‘life after death’ in biggest ever scientific study”
http://www.telegraph.co.uk/news/science/science-news/11144442/First-hint-of-life-after-death-in-biggest-ever-scientific-study.html (- This article is behind a paywall now. But there are many more exceptional accounts on NDERF.org .
How can someone see and hear what is going on in the room when the brain doesn’t function anymore? Our current model does not account for this.
Whenever there is a discrepancy between the model and reality, it is always reality which wins. And it is the model which needs to be adjusted.
This leads to a shift in worldview which has the order of magnitude of the Copernican shift in worldview (if not bigger). Consciousness does not emerge from the brain. It must be the other way round. The brain emerges from consciousness.
Trying to understand how consciousness is created by the brain by studying the electric currents in the neurons is about as promising an endeavor as trying to figure out how the evening news is generated by studying the flow of electrons in the TV.
