GAINESVILLE, Fla. (WCJB) -- A group of scientists has managed to partially revive a dead pig's brain.
Their study, published in the scientific journal "Nature", took the brains from recently- slaughtered pigs and pumped them full of a nutrient-filled, blood-like fluid.
They showed that, on the cellular level, some functions returned, and the artificial blood started to flow.
While this may seem like raising pigs from the dead, University of Florida neuro-medicine expert Katharina Busl says it's more likely to re-define when death actually occurs.
"Death is a concept that - to the extent that we define it in death certificates and so on - a man-made concept because we need to put a stamp on things to make it clear. That's what people really want to have - a clear answer to things," said Busl.
The study was conducted by a team of medical students at Yale.
