Can you imagine anybody's head surviving without the body? For me, it can only happen in storybooks and TV soaps. However, there is a short clip available on the internet from a 1940 motion picture, Experiments in the Revival of Organisms, which blew my mind away. Listen to this.
In the late 1920s, a Soviet doctor named Sergei Brukhonenko kept the head of a dog alive by connecting it to a heart-lung machine.
The heart-lung machine called the 'autojector' supposedly gave the head everything it needed to maintain life.
In this video, you can see the dog's head reacting to sound, touch and how it even used its tongue to taste. After the procedure is completed, the machine is removed and the dog is shown to continue living a healthy life.
