When an 87-year-old man was having his brain scanned, he died — unexpectedly — of a heart attack. So, the scan recorded his unanticipated final brain activity.
Researchers, altering Libet’s classical experiment, found that human brains show no “readiness potential” when a decision is important.
“NDE studies suggest that after physical death, mind and consciousness may continue in a transcendent level of reality.”
Maybe there is no evolutionary explanation. There is certainly no discernible natural-selection benefit.
A major thrust of neuroscience has been the use of fMRI to correlate brain activity with thinking and to draw conclusions about the physical basis of the mind.
