However another school of thought holds that consciousness resides elsewhere (with the soul or spirit) and that the brain is only a kind of filter. Survival after death is therefore possible.
Consider then this story about a man who lives with most of his brain missing... as reported by Science Alert. At first I thought this must be fake news! First described in The Lancet (a well-known medical publication) in 2007, link provided in article.
"A French man who lives a relatively normal, healthy life - despite missing 90 percent of his brain - is causing scientists to rethink what it is from a biological perspective that makes us conscious."
