Changes in statistical parameters during facilitation at the crayfish neuromuscular junction.

Abstract

1. Transmitter release at excitatory neuromuscular junctions of the crayfish was studied at different frequencies of stimulation ranging from 1/sec to 20/sec.2. Over this frequency range the average number of quanta released per stimulus (m) increased with frequency by a factor of 6-7.3. Analysis of the fluctuations in quantal release using binomial statistics indicated that the increase in m was associated with increase in the average quantal release probability (p) at stimulation frequencies between 5/sec and 20/sec. Between 1/sec and 5/sec there was an apparent increase in the number of quanta available for release (n).
