7.这些波动可能与突触后参数，如膜电位，时间常数，或突触激活位点的变异性无关。6.这些数据是最一致的看法，这些EPSP参数的波动的起源是突触前。我们的证据支持的结论是，波动导致的随机性质的发射机释放，而不是从轴突传导或终扣入侵的变化。
7. These fluctuations could not be related to variability in postsynaptic parameters, eg, membrane potential, time constant, or locus of synaptic activation. 6. These data are most consistent with the view that the origin of fluctuations in these EPSP parameters is presynaptic. Our evidence supports the conclusion that fluctuations result from the stochastic nature of transmitter release rather than from variability in axonal conduction or bouton invasion.
