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. Very early one morning four years ago, I awoke with an extremely intense headache. Within hours, my entire cortex—the part of the brain that controls thought and emotion and that in essence makes us human—had shut down. Doctors at Lynchburg General Hospital in Virginia, a hospital where I myself worked as a neurosurgeon, determined that I had somehow contracted a very rare bacterial meningitis that mostly attacks newborns. E. coli bacteria had penetrated my cerebrospinal fluid and were eating my brain.
