The mechanisms underlying synaptic heterogeneity of neurotransmission at mature calyx synapses remain unclear. Here, authors identify two morphological modules that have distinct topology of calcium channel clusters and spatial coupling distance to synaptic vesicles, which may account for different release probability and short-term plasticity in calyces with differing morphology.
