Scientists keep alive brains of decapitated pigs to prompt ethics debate

A team at Yale University have experimented on up to 200 pigs’ heads, taken from an abattoir roughly four hours after the animals’ slaughter, by connecting them to a system called “BrainEx”.

 Neuroscientist Nenad Sestan, who led the team, described their four year-long work to the US National Institutes of Health on 28 March, as reported by MIT Technology Review.
