An experimental brain implant containing 11,000 living neurons can form cellular connections with the brains of mice. Such a device could eventually allow sophisticated control over millions of neurons at the level of individual cells, but without relying on surgically implanted electrodes that penetrate and destroy brain tissue.
The biohybrid implant, developed by the California startup Science Corporation, is different from many others brain-computer interface devices, usually with electrode arrays that are inserted into the brain and sometimes damage cells. In comparison, Science Corporation’s implant is…
