I have just found one paper which you may find interesting:

1.- Jeng JM (2002) Richard Miledi and the calcium hypothesis of 
neurotransmitter release. Nat neurosci, 3, 71-76

This is a very interesting paper which describes historically the
advances in the chemical synapse and the calcium requierement to the
neurotransmitter release.

I hope you find it useful,

regards!

Jose.
