By studying the post-death brain activity in rats, scientists think they may have made a discovery that explains human near-death-experience visions.
People who have recovered from a clinical death often report vivid experiences after their heart stopped beating. Now, scientists think they may have made a discovery that validates those claims.
In a study of rats, University of Michigan researchers found that for a full 30 seconds after the rats’ hearts stopped beating, they continued to show significant brain activity.
The specific readings were of gamma rays, the type of electrical pulses that many associate with human consciousness.
Prior common belief was the brain could no longer work given its greatly compromised supply of oxygen and glucose after the heart stops beating.
Now, the team of neurologists is wondering if higher thought simply doesn’t take as many resources as once believed.
The lead author of the study feels that the discovery opens the doors to future examination of what happens in the human brain as it dies.
Being able to tap into those mental experiences could be the key to retrieving long-desired information about the workings of human consciousness at large.
