File this in the "what the fuck" annals of mad science history: Back in the mid-twentieth century, Soviet scientists did a series of experiements where they kept a dog's severed head alive by connecting it to a machine. Dubbed an "autojector," the device supposedly supplied the dog head with "all that was needed for life." Environmental Graffiti has vintage footage of the dog head eating a piece of cheese, which plops out of its severed neck. Nice. [Environmental Graffiti]
I think if it were real they would have filmed from several different angles, not just the "close to the face" angle. We never see the actual pumps and wires going into its neck. In fact, we never even see the severed part! I think they just poked a cute dog's head through a hole in the table and made it lick its nose.
