The role of extracellular calcium in exo- and endocytosis of synaptic vesicles at the frog motor nerve terminals

In the present study we combined FM 1-43 imaging and electrophysiological recording of miniature end-plate currents (MEPCs) to determine the role of extracellular calcium in synaptic vesicle exo- and endocytosis at the frog motor nerve terminals. We replaced extracellular Ca 2+ ions with other bival...
