One-Step Optogenetics for Hacking the Nervous System

Engineers have taken one of biotech’s hottest tools—optogenetics—and made it better. The 12-year-old technique, which enables scientists to control brain cells with light, typically requires a multi-step process and several surgeries on animal models. Polina Anikeeva at the Massachusetts Institute of Technology (MIT) and her colleagues came up with an engineering solution that combines those
