Scientists restore some function in pig brains four hours after death in research that could lead to stroke treatments
Three-week-old pigs in Walcott, Iowa. By Joel Achenbach Joel Achenbach Reporter covering science and politics Email Bio April 17 at 1:00 PM The brain is fragile, and if deprived of oxygen — for example from a massive heart attack, or through drowning — it will quickly and catastrophically degrade, leading to irreversible brain death. And that’s it — the end.
The pig brains remained, by any traditional definition, dead. The researchers detected no signs of consciousness or any other “global” mental activity. But the study suggest that brain cells are hardier than previously thought, said study co-author and Yale neuroscientist Nenad Sestan. This startling research provides the latest reminder that science and medicine continuously create innovations that offer hope for treating dreaded diseases while simultaneously raising head-scratching issues about how to apply transformative technologies and procedures.
Moreover, the experiment employed a chemical that inhibited overall brain activity. The scientists say that helped brain cells avoid stress. But the blocker also ensured the pig brain would not have any risk of awareness.
