Synaptic Facilitation: Long-Term Neuromuscular Facilitation in Crustaceans

R. G. Sherman 1 and H. L. Atwood 1

1 Department of Zoology, University of Toronto, Toronto, Ontario, Canada

Continuous stimulation at frequencies equal to or greater than 5 hertz for 20 to 30 minutes results in a two- to fivefold increase in the amplitudes of excitatory postsynaptic potential recorded from certain stretcher and opener muscles of decapod crustaceans. This long-term facilitation appears to result from an accumulation of sodium ions within the nerve terminals. It persists for at least 1 hour after stimulation has stopped.
