Scientists have revived their severed pig heads. Their brains functioned without bodies
Experiments to keep the brain working outside the body have so far been carried out in pigs, but scientists say they are in the process of being prepared to conduct them on other animals. Over 100 brains were used in the course of the experiments. They were connected to an external artificial circulatory system and the fluids warmed. Scientists managed to keep their brains alive for over 36 hours.
