Comments "The best physiological description of how an action potential induces phasic, synchronous neurotransmitter release was obtained for the synapse formed by the calyx of Held, the only synapse for which models are available that accurately account for all properties of release (reviewed in Meinrenken et al. 2003). The calyx of Held forms a large nerve terminal (~15 µm diameter) that envelops the soma of the postsynaptic neuron like a cup, hence its name."
