Accurately controlling neurons with light could revolutionize the study and treatment of the brain. Light control: This optical micrograph shows a three-dimensional array of optical probes illuminated in an arbitrary pattern using a laser and tiny mirrors. The optogenetic device can activate brain cells in predetermined patterns. Optogenetics, which pairs light-sensitive genes with a light source to selectively switch brain cells on or off, has shown promise as a research tool and a potential therapy. But the technology mostly delivers light to one spot, whereas brain activity usually involves complex sequences of activation in different locations. A new device takes optogenetics into three dimensions, with the ability to send patterns of light to neurons at various coördinates in the brain.
