Summary

Fast, slow and fast multiquantal spontaneous junctional currents were recorded from glutamate sensitive muscle fibres ofDrosophila larvae. Decrease of temperature and hyperpolarization prolonged the time course of fast currents. Ethanol (0.4 M) markedly shortened their duration, whereas several other drugs known to modify the time course of currents at cholinergic synapses were ineffective at this neuromuscular junction.
