Existing optogenetic silencing methods affect membrane potential, biochemistry or protein integrity. Here, the authors demonstrate an approach for silencing synaptic transmission that combines fast activation and reversibility, by using nondisruptive, reversible, light-evoked clustering of synaptic vesicles, which they validate in Caenorhabditis elegans, zebrafish, and murine cell culture.
