Hey guys! Since more bone-chilling science was requested. I absolutely NEEDED to make this post.
In 1940, Russian scientists released a video of a severed dog head. They were kept alive for several hours, wiggling their ears in response to sounds and even licking their mouths.
The scientists claimed they could keep the animals alive by an artificial blood circulation system.
Isn’t that intense? You can watch the full video here
In 2005, American scientists created another pack of zombie dogs. The team rapidly killed the dogs by flushing all the blood from their bodies and replacing it with oxygen- and sugar-filled saline.
Three hours later, the team gave the dogs a blood transfusion, and an electric shock.
The dogs were resurrected, and while some had permanent damage, most were no worse for wear.
This research suggested that the treatment could one day revive people who are bleeding too quickly for doctors to repair their injuries.
And in fact they can now.
I have stumbled upon an article that say scientists can save people by draining all their blood out.
You can read more about that here
The severed head is not alive. Its reflexes are merely being stimulated by electric shocks.
