Topic: optical fiber

Optogenetics is an invaluable technique in neuroscience to study brain circuits. However, conventional optogenetic systems for rodents use optical fibers tethered to steady-state lasers to deliver light to the brain, which increases animal’s anxiety and hinders natural behavior. Therefore, we developed a novel wireless headstage that simplifies integration in closed-loop experiments with optogenetics. For the first time, we present a wire-free headstage to deliver light to the brain through either an optical fiber or a custom-designed and fabricated µLED-integrated neural probe.The reusable he
