Abstract
During prolonged stimulation, fusion of thousands of synaptic vesicles poses a challenge for the temporal and spatial coordination of exocytosis and endocytosis. In this issue of Neuron, Hosoi and colleagues reveal that [Ca2+](i)-microdomains trigger compensatory endocytosis. Block of endocytosis enhances short-term depression by delaying vesicle recruitment to docking sites on active zones.
