A study published by the journal Nature reveals that US scientists have partially revived pig brains four hours after the animals had died.

The study found that the death of brain cells could be halted and that some connections in the brain were restored.
The Yale University scientists connected dead pig brains to a system that mimicked pumping blood to the organ.
During this process, the brains showed a reduction in cell death, some activity, and the restoration of blood vessels.
However, the brains did not show signs of awareness and were fundamentally still dead.
