Chemical synapses also serve to amplify neuronal signals, so that even a small presynaptic nerveterminal can alter the response of a large postsynaptic cell.

It is postulated that the decreased release of acetylcholine from the nerveterminal reflects a competition of the antibiotic or magnesium with calcium for entry into the terminal.
