Popis: Optogenetic actuation regimes are often static, which allows perturbation, but not true control of neuronal activity. Here, the authors describe an all-optical method for bidirectional steering of membrane potential, in closed loop, in C. elegans muscles and neurons, and rat hippocampal slice culture. The ‘optogenetic voltage clamp’ uses two microbial rhodopsin actuators and the rhodopsin voltage indicator QuasAr.
