Controlling neurons with light -- but without wires or batteries

In optogenetics, scientists use light to turn groups of neurons in the brain on or off. New research demonstrates a new optogenetics method that eliminates the need for bulky optical fibers, gives researchers more precise control of the light's intensity, and allows for stimulating multiple areas of the brain simultaneously.
