Research team led by by Dr. Sam Parnia from Stony Brook University School of Medicine in New York made a curious statement about "life after death."
Sam Parnia has been researching human cardiopulmonary resuscitation for many years. And including many times he came across the fact that people who survived clinical death talked about their unusual visions and sensations.
The goal of Parnius' team's research is to improve the quality of resuscitation and prevent brain damage when the heart is restarted.
This time, the team studied cases of cardiac arrest in patients from the United States and European countries. And it turned out that the brains of these people were still working when they were already pronounced dead.

The brain worked so well that patients for a short amount of time continued to hear the voices of doctors around them and to be aware of everything. Survivors of heart attacks talked about what happened around them when they were already considered dead after the heartbeat stopped. They even heard the doctor talk about the time of their death.
"They described the negotiations between doctors and nurses in detail, described what the situation was," - says Sam Parnia in an interview with LiveScience. stop at the same time."
"As soon as the heart stops, blood no longer circulates to the brain, which means that your brain's brain activity stops almost instantly. You lose all your brain reflexes, including the gag reflex and the accessory reflex, it all goes away."

However, research by Parnia's team shows that this is actually not the case. The functions of the brain responsible for thinking seem to "fade" and no brain activity is visible on the monitors. But in fact, brain cells can be active even for several hours (!)after the official death of a person.
According to Sam Parnia, there is nothing mysterious about this, since perhaps this is the "fault" of the procedure of cardiopulmonary resuscitation (CPR), during which a small amount of blood is sent to the brain, about 15% of the norm. And this is enough to slow down the death of brain cells, but not enough to give the brain a boost to work at full strength. Therefore, no reflexes are noticeable during CPR.
"If you do manage to restart the heart, the brain will gradually start working again at full strength. And the longer doctors do resuscitation, the more they slow down the processes of dying and the failure of the brain from functioning."
