The study of brain organoids is leading to a better understanding of human development and potential therapies for neurological disorders. Yet when people hear the phrase "brain in a dish" it instantly brings to mind the stuff of science fiction - labs full of sentient brains thinking and plotting. Alysson Muotri explains why these organoids should not called "brains in a dish" and how they are being used to explain human processes previously inaccessible to study. While underscoring scientific value of these organoids, he also raises the question of what ethical questions demand an answer as the technology improves. Series: "Stem Cell Channel" [Show ID: 35245]
