A 3-D Optogenetics Chip Developed At The MIT Media Lab Promises Better Control Of The Brain


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.
