After death, people realize that they have died and understand what is happening around them, said scientists from the Langone School of Medicine at New York University. The words of researchers are given by the online edition of LiveScience. Doctors define death by the moment of cardiac arrest: the blood ceases to flow to the brain, which leads to an almost immediate cessation of his work. Eventually, the brain cells begin to die, but it may take several hours after the clinical death, says research leader Sam Parnia. Also, as reported, the human consciousness does not immediately turn off when the heart stops. People in the "first phase of death" can still give some signs of consciousness.

A significant proof of this are the cases when people who survived heart failure could describe in detail what was happening around after a clinical death. "They can tell that they saw doctors and nurses at work and heard their full conversations - facts they otherwise might not know," said Parnia. According to the researcher, these memories were also confirmed by doctors, surprised that their patients, who were, in fact, dead, remembered all these details. As previously reported, earlier scientists found a simple way to avoid cardiovascular diseases. Scientists have found a way to slow down aging Author: 1.
