Yale University scientists have succeeded in restoring basic cellular activity in pigs’ brains hours after their deaths in a finding that may one day lead to advances in treating human stroke and brain injuries, researchers reported Wednesday.
The scientists emphasized that their work did not even come close to reawakening consciousness in the disembodied pig brains. In fact the experiment was specifically designed to avoid such an outcome, however improbable.
Still, the study raises a host of bioethical issues, including questions about the very definition of brain death and potential consequences for protocols related to organ donation.
