Zombie Pigs: Scientists Revive Pig's Brains Four Hours After Death

American scientists partially restored the pig's brain ten hours after slaughtering animals. An experiment by scientists from Yale University can help in the study of Alzheimer's disease.

The study raises questions about the boundary between life and death and questions the assumption that the brain dies in a matter of minutes after a cardiac arrest.

The brain was taken from the animal four hours after slaughter and connected to a system through which a special liquid was pumped rhythmically, simulating heart contractions. This “cocktail” included artificial blood, which supplied the brain with oxygen, and medications designed to slow down or even reverse the death of brain cells.

As stated in the study, scientists were able to partially reverse the death of brain cells - ten hours after the pig's head was cut off, they achieved a partial response from its brain to medications and partially established communication between neurons.

Also, the level of oxygen consumption by the brain corresponded to a healthy state.

However, the brain still could not be considered alive - only a small part of the neurons communicated with each other. Nothing like coordinated electrical impulses has been discovered, indicating what is called consciousness or intelligence. On an encephalogram, such a brain would not look alive.

This experiment shows that the death of brain cells is a long and gradual process, Nenad Sestan, professor of neurology at Yale University, comments on the experiment.

“Brain cell death is taking longer than we thought,” he says. “In addition, we have learned that some of these processes can be slowed down, delayed or reversed,” the scientist notes.
