Chinese Researchers Revive Isolated Pig Brain 50 Minutes After Detachment, Extending the “Salvageable” Window for Brain Tissue.
On August 23, a team of Chinese researchers announced a result that, at first glance, sounds like it belongs in a science‑fiction novella. Using a novel “ex‑vivo brain maintenance” system, they were able to restore measurable activity in the brain of a pig whose head had been detached from its body for 50 minutes after cardiac arrest. The work, led by Professor He Xiaoshun of the Organ Transplant Center at the First Affiliated Hospital of Sun Yat‑sen University, marks the first time an isolated mammalian brain has been revived beyond the five‑to‑eight‑minute window that has long been regarded as the hard limit for rescuing brain tissue after the heart stops.
