spontaneous exocytosis of neurotransmitter
The release of a neurotransmitter into the synaptic cleft, where the release step is independent of the presence of calcium ions (Ca2+). The neurotransmitter is contained within a membrane-bounded vesicle, and is released by fusion of the vesicle with the presynaptic plasma membrane of a nerve cell.
