NEW YORK (AP) — Scientists restored some activity within the brains of pigs that had been slaughtered hours before, raising hopes for some medical advances and questions about the definition of death.
The brains could not think or sense anything, researchers stressed. By medical standards “this is not a living brain,” said Nenad Sestan of the Yale School of Medicine, one of the researchers reporting the results Wednesday in the journal Nature.
But the work revealed a surprising degree of resilience among cells within a brain that has lost its supply of blood and oxygen, he said.
