Comparison of FM1-43 staining patterns and electrophysiological measures of transmitter release at the frog neuromuscular junction
{{output}}
Frog motor nerve terminals were stained with the activity-dependent dye FM1-43, which appears to stain recycled synaptic vesicles. Superficial end plates which could be visualized in their entirety were imaged and end plate potentials (EPPs) evoked by low freq... ...
