The effect of reduced calcium on quantal unit current and release at the crayfish neuromuscular junction


Excitatory postsynaptic currents (EPSCs) were recorded extracellularly from large muscle fibers by means of ‘patch clamp’ electrodes. Compared to usual extracellular recordings, better signal/noise ratio and temporal stability were achieved. In the range of extracellular calcium concentrations [Ca]0 between 2.7 and 13.5 mmol/l (normal), the average… (More)
