Dead pigs’ brains have been partially revived in a study that upends established wisdom about what happens when we die, raising serious ethical questions even though researchers claim the brains never regained consciousness.
Disembodied pig brains subjected to an experimental preservative procedure showed some restored cellular and molecular function and even some synaptic activity, researchers discovered, observing these “signs of life” ten hours after the animals had been killed.
The brains of ordinary pigs, taken from a slaughterhouse, were cleansed and cooled, then pumped full of a chemical cocktail designed to slow their deterioration, and the results – published Wednesday in the journal Nature – are striking.
