Combining organoids and circuits could allow researchers to leverage the speed and energy efficiency of human brains for AI, says Guo.

The technology could also be used to study the brain, says Arti Ahluwalia, a biomedical engineer at the University of Pisa in Italy, because brain organoids can replicate the architecture and function of a working brain in ways that simple cell cultures cannot. There is potential to use Brainoware to model and study neurological disorders, such as Alzheimer’s disease. It could also be used to test the effects and toxicities of different treatments. “That’s where the promise is; using these to one day hopefully replace animal models of the brain,” says Ahluwalia.
