An Experiment With a Live Severed Head

After a head is severed from the body, its function continues for a few minutes more. A Russian scientist, Doctor Sergei S. Bryukhonenko, in some controversial experiments attempted to keep a dog's head alive for an extended amount of time after it had been lopped off and was clinically dead.

You can watch the film that was made of the experiment and see the head with four tubes connected.

Lungs, which sit in a tray, are oxygenated by bellows. A primitive heart-lung machine called the autojektor supplies the canine head with oxygenated blood.

The film is disturbing and freaky, watch it if you dare.
