has participant serotonin(1+) serotonergic neuron chemical synaptic transmission synaptic transmission, serotonergic biological_process The vesicular release of serotonin from a presynapse, across a chemical synapse, the subsequent activation of serotonin receptors at the postsynapse of a target cell (neuron, muscle, or secretory cell) and the effects of this activation on the postsynaptic membrane potential and ionic composition of the postsynaptic cytosol. This process encompasses both spontaneous and evoked release of neurotransmitter and all parts of synaptic vesicle exocytosis. Evoked transmission starts with the arrival of an action potential at the presynapse. dos 2017-07-05T14:16:51Z GO:0099153 serotonergic synaptic transmission
