Scientists restore brain circulation and cellular function in post-mortem pig brains

In a recently published study in Nature, researchers have reported that circulation and cellular activity were restored in a pig’s brain for 4 hours after its death – a finding that not only raises ethical and legal questions about the nature of death and consciousness, but also challenges the long-held assumptions about the irreversible nature of the cessation of some brain functions after death.

The research team obtained the brain of a post-mortem pig from a meatpacking plant, where it was then isolated and circulated with a specially designed chemical solution. Many of the basic cellular functions that scientists once thought to cease seconds or minutes after oxygen and blood flow cease, were observed, according to the investigators.
