Certain brain function restored in pig hours after death.
Brain function partially restored in pig after death - interesting science news

Immediately after death, once the oxygen and blood supply is cut off, the electrical brain activity disappears immediately, while the energy stores get depleted within minutes. This has always lead to believe that brain functions end after death irreversibly.

Now, researchers restored the circulation and cellular activity in the pig’s brain 4 hours after its death. The circulated a uniquely formulated solution specially made to preserve brain tissue and found that neural cell integrity was preserved and certain neuronal functions were restored.

While this technique does not have any immediate application, it could be used in future to salvage brain function in stroke patients and test new drugs for brain cellular recovery after injury.
