Scientists performed a miraculous feat by restoring some functionality in pig brains – four hours after the death of the pigs.
32 pigs had their heads decapitated in the experiment. Tubes were placed in the pigs brains and a chemical mixture meant to mimic blood was injected into the brains. Some cellular activity was observed to have resumed as if the brain were still alive.
The study says billions of neurons resumed normal operation and the deaths of other brain cells were reduced over the course of six hours after the experiment began. The firing of synapses, which are the connections between neurons, was observed. The study is perhaps the first real evidence that the notion of death being irreversible may not be completely true.
One author of the results of the study remarked that the results were "unexpected" and believed this experiment would produce similar results if performed on humans.
Although some "life" was restarted in the brains, electrical activity in the brain that is associated with awareness and perception was not observed. So the pigs were not truly brought back to life akin to Frankenstein.
The scientists who studied the results of the experiment believe it is only scratching the surface of these types of "resurrections," but they agreed that restoring complete consciousness in a dead brain is still very far away from becoming a reality.
