Calmodulin inhibitor W-7 did not cause changes in the quantal content of postsynaptic end-plate potentials (EPP) in newly formed synapses, but prevented facilitation of acetylcholine secretion induced by L-type Ca(2+)channels blocker nitrendipine. CaMKII inhibitor KN-62 produced similar effect and suppressed

L-type Ca(2+) channels in mammalian brain neurons have either a Ca(V)1.2 or Ca(V)1.3 pore-forming subunit. Recently, it was shown that Ca(V)1.3 Ca(2+) channels underlie autonomous pacemaking in adult dopaminergic neurons in the substantia nigra pars compacta, and this reliance renders
