Figure 9. Model-simulated S631A currents in the absence and presence of low (10 μm) and high (2 mm) Ba²⁺ concentrations (A) and their representative current-voltage relationships under control conditions and in the presence of 10, 500 μm and 2 mm Ba²⁺ (B).

Note the similarity of the simulated current profiles to experimental results (Fig. 5).
