Calcium transients for different numbers of shells

Calcium transients in the (a) submembrane shell and (b) cell core (central shell) for different total numbers of shells. Black line: 11 shells. Gray dashed line: 4 shells. Blue dotted line: 2 shells. Diameter is 4 μm and the submembrane shell is 0.1 μm thick. Other shells equally subdivide the remaining compartment radius. All other model parameters are as in Figure 6.5.

Simulation environment:

Note that the simulation plots correctly show the calcium transients all beginning after the stimulus at 20 msecs, unlike the figure in the book in which part (b) has a spurious time shift! (This is a drawing error, not a simulation error).
