Abstract: Optogenetics, a technique to precisely manipulate cell activity by genetically encoded light-sensitive proteins, has been widely and enthusiastically applied as a revolutionary tool in the field of neuroscience. As one of the most representational proteins, channelrhodopsin-2 (ChR2) has been regarded as a prominent tool that contributes to a series of breakthrough in the field of system neuroscience. In this paper, we review the discovery, molecular structure and function of ChR2. We also review the advances of using ChR2 to map cerebral functional connectivity and to study the modulation of neural function, with a prospect for its future application.
