Proof of Heaven: A Neurosurgeon's Near-Death Experience and Journey into the Afterlife by Harvard brain surgeon Dr. Eben Alexaner captured the cover of Newsweek! In Heaven Is Real: A Doctor’s Experience With the Afterlife, Dr. Alexander says:

​

"As a neurosurgeon, I did not believe in the phenomenon of near-death experiences. I grew up in a scientific world, the son of a neurosurgeon. I followed my father’s path and became an academic neurosurgeon, teaching at Harvard Medical School and other universities. I understand what happens to the brain when people are near death, and I had always believed there were good scientific explanations for the heavenly out-of-body journeys described by those who narrowly escaped death...

​

In the fall of 2008, however, after seven days in a coma during which the human part of my brain, the neocortex, was inactivated, I experienced something so profound that it gave me a scientific reason to believe in consciousness after death. I know how pronouncements like mine sound to skeptics, so I will tell my story with the logic and language of the scientist I am."
