The human brain can continue functioning for more than 10 minutes after the body has died, scientists have discovered.
Intensive care doctors reported observing the same kind of brain waves in a patient whose pulse had stopped and whose pupils were unreactive as occurs during deep sleep in healthy people. Researchers had previously thought that brain activity ends before or shortly after the heart stops beating, although two studies last year demonstrated that genes continue to function, in some cases more energetically, in the days after people die.
