The ability to stimulate neural circuits with very high precision light to control cells—optogenetics—is key to exciting advances in the study and mapping of the living brain. In the current state of the art, spatially patterned light projected via free-space optics stimulates small, transparent organisms and excites neurons within superficial layers of the cortex.
