They were honoured for their discoveries concerning light-gated ion channels and optogenetics.\n\nHegemann and Nagel discovered channelrhodopsin, a light-sensitive ion channel that opens rapidly when exposed to light. Deisseroth introduced its gene into nerve cells and showed that blue light could trigger a nerve signal, later making the switch work in the brains of living mice.\n\nThe method lets researchers turn individual neurons on or off and test cause and effect in brain circuits. The three share the 12 million Swedish kronor prize (about US$1.2 million) equally."}}
