Abstract

Single-synapse microscopy STED (stimulated emission depletion) microscopy is an emergent light microscopy technique that overcomes the diffraction barrier limiting the resolution of conventional fluorescence microscopes. This brings structures the size of the synaptic vesicles (40 nm) into the picture. Now STED microscopy has been used to resolve individual synaptic vesicles in single synapses of the mammalian central nervous system for the first time. The synaptic vesicle recycling that is central to neurotransmitter release has been intensely studied for more than 30 years, but a major question has remained unanswered: do their components diffuse on the plasma membrane, or do they remain together? STED microscopy reveals that at least one main component, synaptotagmin-1, remains clustered after exocytosis and is recycled en bloc.
