Enhancement of asynchronous release with an increase of Uar in the SAR model. (A) The IPSCs caused by total transmitter release. (B) The synchronous component of the IPSC caused by synchronous release. (C) The asynchronous IPSC caused by asynchronous release. (D) The internal state usr of the synapse model during the spike train. (E) The internal state Uar during the spike train. (F) The internal state x (with a scale of 1:XF) during the spike train. Note that asynchronous release causes a decrease in the synchronous release due to the competition of vesicle resources. Parameters: taken from Table 1, except Uar as indicated. Ax0 = 10 pA.
