After years of studying alongside Carmelite nuns, Mario Beauregard, neuroscientist and author of “The Spiritual Brain,” argues a religious experience goes beyond an event in our brain, random neurons firing, or simple delusions, but can occur through a higher power outside of our brain and body. In this interview, Dr. Mario Beauregard speaks with Dr. Oz, and shares evidence and stories of near death experiences that link what many researchers rarely consider.
