It’s a controversial topic especially since there are people who claim to have died, went to heaven, and lived to tell the tale but what is the truth behind these “out-of-body” or “life-after-death” experiences?

Over the last decade, Dr. Sam Parnia of NYU’s Langone School of Medicine has tracked the brain activity of thousands of subjects in the United States and Europe, charting what happens to the brain in the minutes and hours after cardiac arrest — when the heart ceases to beat. He said that following the loss of heartbeat, brain function ceases “almost instantaneously” and the body stops producing basic reflexes such as gag reflex or pupil dilation.
However, Parnia said, a surprising number of patients who have been brought back to life report having had the capacity to see or hear even after being officially declared dead. Some clinically dead patients who have been revived, he said, describe “watching doctors and nurses working… having awareness of full conversations, of visual things that were going on, that would otherwise not be known to them.”
Given this, how can we then explain what happens in somebody’s brain or body when they are declared clinically dead but were able to be revived several minutes or maybe even a longer period of time later?
