Borst and Sakmann (1996) (17) showed that excitatory postsynaptic currents (EPSCs) are linear summations of quanta (mEPSCs) at the calyx synapse, consistent with the quantal hypothesis.

Distribution of mEJPs latencies in all lines were best-fitted with a monoexponential equation predicted by the Poisson model well, thus confirming that under all experimental conditions, the random nature of spontaneous quantal release is not altered.

However, making a quantal distinction between dangerously high [E.sub.2] concentrations (>2000 pmol/L) and typical premenopausal concentrations (200-800 pmol/L) did not require quantitative accuracy at physiological [E.sub.2] concentrations.

Such evidence lends support to the idea that NO increases the presynaptic quantal release of GABA and the open probability (P0) of [GABA.sub.A] channels, since IPSC currents were abolished by the [GABA.sub.A] channel blocker, picrotoxin (82).
Effects of nitric oxide on magnocellular neurons of the supraoptic nucleus involve multiple mechanisms
Synaptic vesicles in the presynaptic terminals release their contents continuously, even at rest, into the synaptic cleft (quantal release) that contributes to the miniature excitatory postsynaptic potential (mEPSP) recorded from the neuronal soma (Figure 1(a)).
