Balls of human brain cells grown in a dish, known as organoids, have been linked to computers and used to solve mathematical equations. The work is an early step towards using living brain tissue as a form of artificial intelligence, but this goal may raise ethical questions in the future, researchers say.
In a paper posted online before peer review, Feng Guo at Indiana University Bloomington and his colleagues say they have created “living AI hardware that harnesses the computation power …
