Presynaptic calcium dynamics at neuromuscular junction (Stockbridge, Moore 1984)

The diffusion of calcium is effectively reduced by the ratio of bound to free calcium. Treating the release magnitude as proportional to the fourth power of calcium concentration next to the membrane gives reasonable facilitation with very little release between spikes.
