🤖 Artificial Brain Controls a Robo-Dog
Researchers at the University of California, San Diego, have developed a new method for growing human brain organoids using graphene. The resulting artificial mini-brain was successfully connected to a robotic dog, which responded to signals from the organoid during tests.
🧠 How Does It Work?
Previously, organoids were stimulated with electric signals, which might harm neurons, or with light, which required prior genetic modification of the cells. Scientists improved the procedure by growing organoids on graphene substrates that convert light into moderate electrical impulses. These signals promote development and reinforce brain connections, while their low intensity allows for more precise control of organoid growth.
The organoid grown this way was connected to a robo-dog. In 10 tests, the dog successfully navigated obstacles by responding to signals from the artificial brain. The delay between signal detection and command execution did not exceed 50 ms.
"This is a game-changer for brain research. We can now speed up brain organoid maturation without altering their genetic code, opening doors for disease research, brain–machine interfaces, and other systems combining living brain cells with technology," says Alysson Muotri, corresponding author of the study.
