DOI: 10.1016/j.cub.2020.09.056
Abstract: Channelrhodopsins (ChRs) are light-gated ion channels widely used as optogenetic tools for manipulating neuronal activity. The currently characterized ChR families include green algal and cryptophyte cation-conducting ChRs (CCRs) and cryptophyte, haptophyte, and stramenopile anion-conducting ChRs… read more here.
