A new tool for neuroscientists delivers a thousand pinpricks of light to individual neurons in the brain. The new 3-D "light switch", created by biologists and engineers, could one day be used as a neural prosthesis that could treat conditions such as Parkinson's and epilepsy by using gene therapy to turn individual brain cells on and off with light.
