According to a report by Gizmodo, a neuroscientist from Yale University has claimed to have developed a technique to preserve the brain tissue of pigs for an extended time following decapitation. As originially reported by Antonio Regalado reports in MIT Technology Review, Yale neuroscientist Nenad Sestan described the technique, called BrainEx, which restores circulation to decapitated brains using a system of pumps, heaters, and oxygen-rich artificial blood warmed to body temperature.
