Readily releasable pool

WebA readily releasable pool of quanta, tentatively identified with docked synaptic vesicles, has been defined by analysis of the neurotransmitter release caused by application of … WebThe readily releasable docked pool is tethered to the plasma membrane at the active zone. Upon fusion, neurotransmitter is released into the cleft between the axon terminal and spine. Neurotransmitter diffuses across the cleft and is bound by ligand gated ion channels (neurotransmitter receptors) on the postsynaptic surface. ...
