(New Scientist) – Reperfusion technologies that can reanimate human brains are raising the possibility that death could be a reversible condition, even hours after a cardiac arrest

That was when something incredible happened. The cortex turned from grey to pink. Brain cells started producing proteins. Neurons juddered back to life, displaying signs of metabolic activity indistinguishable from that of living cells. Basic cellular functions, activities that were supposed to irreversibly cease after blood flow stopped, were restored. The pig’s brain wasn’t alive, exactly – but it certainly wasn’t dead.

Now, for the first time, the team is using the technique on human brains. (Read More)
