Short-Term and Long-Term Plasticity Mediated by Changes in Responding Synapses at Crustacean Neuromuscular Junctions

Neuromuscular junctions of crustaceans have been frequently employed as model systems to investigate mechanisms of synaptic plasticity (reviews by Atwood, 1976, 1982). The large size of the individual motor neurons and their limited number permit investigations of synaptic physiology and morphology at the level of individual nerve terminals and even of individual synapses. Furthermore, crustacean neuromuscular junctions display physiological properties akin to those of synapses in the central nervous systems of both vertebrate and invertebrate species. Several forms of short-term and long-term synaptic plasticity have been described, and cellular mechanisms of these are under investigation.
