Soviet RESURRECTION Experiment Video!
A video filmed in the 1940s, shows how the Soviets successfully resurrected a severed dog head, also how they were able to stop a heart of a dog for up to 15 minutes and resurrect it again with blood circulation mechanism, with surprisingly no brain damage! From what I understand this is real historically documented footage.
