Scientists Restore Some Function In The Brains Of Dead Pigs

The image on the left shows the brains of pigs that were untreated for 10 hours after death, with neurons appearing as green, astrocytes as red and cell nuclei as blue. The image on the right shows cells in the same area of brains that, four hours after death, were hooked up to a system that the Yale University researchers call BrainEx.

The cells regained a startling amount of function, but the brains didn’t have activity linked with consciousness. Ethicists see challenges to assumptions about the irreversible nature of brain death.
