Effect of InsP3 concentration on the distribution of Ca2+ signal amplitudes with a 25 closely packed channel cluster. A stochastic simulation was performed under the same conditions as for Fig. 3A (d = 12 nm), but with InsP3 concentrations equal to 0.35, 0.5, 0.65, and 1 μM in A, B, C, and D, respectively.
