From Hollywood directors to your death obsessed neighbor, everyone has an opinion on what happens to your body after you die.
But a new study published in the Canadian Journal of Neurological Sciences says that the brain can be active for up to 10 minutes after a person has been declared clinically dead.
The researchers observed what happened in four critically ill patients when they were taken off life support. They found brain activity only persisted with one of the patients after the final heartbeat. The patient had the same kind of brain waves seen during deep sleep.
Interestingly, the researchers noted all four patients brains reacted differently once they were declared clinically dead. Meaning what happens after death likely changes from person to person.
The researches didn't have a reason as to why patients reacted differently and didn't say if it had to do with previous illnesses.
