In vertebrates and invertebrates, neuronal communication is mediated by chemical synaptic transmission via release of transmitters that bind to receptors and result in a postsynaptic response. The release of the transmitter is mostly triggered by a transient release of intracellular calcium, brought about by activation of voltage-gated calcium channels.
