Discrete-State Stochastic Models of Calcium-Regulated Calcium Influx and Subspace Dynamics Are Not Well-Approximated by ODEs That Neglect Concentration Fluctuations
Figure 9
Subspace volume-dependence of concentration fluctuation and channel open probability for multiple calcium-inactivated channels. (A) Steady-state probability distribution for = (a) , (b) , and (c) ( μM, μM−2 ms−1). (B) Steady-state and as a function of ( to 0.15 μM−2 ms−1).
