WebAnalysis with a recently established sequential two-step vesicle priming model indicates an increase in the abundance of fully-primed and slowly-recovering vesicles. A systematic analysis of short-term plasticity and synapse-to-synapse variability of synaptic strength at various types of synapses revealed that stronger synapses generally recover more slowly … WebIn neuronal synapses, a pool of neurotransmitter-ﬁlled vesicles is aggregated at the synaptic active zone, where membrane fusion takes place. During synaptic activity, clathrin-mediated endocytosis of synaptic vesicles has been shown to be critical for sustaining neurotransmitter release (Slepnev and De Camilli, 2000).
