PLAYING GOD: Pig brains revived in move which could see humans brought BACK FROM THE DEAD | Science | News


The Frankenstein-esque experiment saw scientists revive the brains of around 200 pigs which were brought in from slaughter houses.

The brains were resuscitated through a series of tubes fed into the head which pumped heat and artificial blood into the brain.

Scientists from Yale University said that billions of cells in the brain began acting normally again.

However, the scientists were sure that the animals did not regain consciousness.

But, the experts theorised that if the technology in the field does evolve and become better, then in the future it could be used to bring humans back from the dead.

Yale University neuroscientist Dr Nenad Sestan, who led the research, said: “That animal brain is not aware of anything, I am very confident of that.

“Hypothetically, somebody takes this technology, makes it better, and restores someone’s [brain] activity.

“That is restoring a human being. If that person has memory, I would be freaking out completely.”

Doing so would open up a huge ethical discussion, and for that reason Dr Sestan did not elaborate on the results, choosing to keep the majority of the findings secret until they are published in a scientific journal.

Dr Sestan explained the results to an audience at a meeting at the National Institutes of Health (NIH) in Maryland where he described the results as “mind-boggling” and “unexpected”.

He added that the technique could work on a number of species, including humans: “This is probably not unique to pigs.”

Steve Hyman, director of psychiatric research at the Broad Institute in Cambridge, Massachusetts, and someone who was briefed on the study beforehand, told MIT Technology Review: “These brains may be damaged, but if the cells are alive, it’s a living organ.

“It’s at the extreme of technical know-how, but not that different from preserving a kidney.”

Mr Hyman also implied that the outstanding study could lead to life-extending practices for humans.

He said: “It may come to the point that instead of people saying ‘Freeze my brain,’ they say ‘Hook me up and find me a body’.”
