People reportedly know when they are dead, study reveals

According to a study, individuals know when they are dead since the human brain still works for a short time after death.

This discovery was made when the researchers, from New York’s Stony Brook University of Medicine, look at cardiac arrest cases in Europe and the US, as reported by Unilad.

"They’ll describe watching doctors and nurses working, they’ll describe having awareness of full conversations, of visual things that were going on, that would otherwise not be known to them," said Dr. Sam Parnia, who led the research.

The blood quits circulating to the brain after the heart stops pulsating. The brain at that point starts to shut down.

"It [the time a patient is declared dead] is all based on the moment when the heart stops. Technically speaking, that’s how you get the time of death," Dr. Parnia added.

The blood quits circulating to the brain after the heart stops pulsating. The brain at that point starts to shut down.

This process, however, can take hours to finish, leaving a moment where a person is officially dead and still mindful of what’s going on around them.

The researchers also revealed how the deceased person could even hear themselves being declared dead.

They are now hoping their work would help enhance treatment of cardiac arrests and avoid brain injuries amid resuscitation.

"At the same time, we also study the human mind and consciousness in the context of death, to understand whether consciousness becomes annihilated or whether it continues after you've died for some period of time — and how that relates to what's happening inside the brain in real time," Dr. Parnia explained.

The research also shows that there is some sort of life after death.
