Distribution of puff sizes: change of behavior with the radius of influence and comparison with observations.

We show the probabiliy, , of having a puff with open channels obtained with our model for , , and (solid circles), (open circles) and (triangles). Each curve corresponds to 500 realizations of the model. We observe a transition from a Ca-dominated to a IP-binding dominated stochasticity distribution as increases. Superimposed with bars: experimental data taken from Fig. 4D of [1].
