TRANSMITTER release from nerve endings is believed to be triggered by the influx of Ca2+, which is thought to enter the terminal as a result of an increase in conductance produced by the action potential1. At the neuromuscular junction the evidence for the role of Ca2+ is largely indirect, based on changes in endplate potential (e.p.p.) amplitude following variations in [Ca2+]0. Miledi2 showed that microinjection of Ca2+ into the presynaptic terminal at the synapse of the squid giant axon… CONTINUE READING
