Figure 6. Simulation of K⁺ BK channel blocker application. (A) AP firing (V_p); (B) [Ca²⁺]_c (– – –) and relative IS (——). The maximal conductance (g_mkcab,Eq. A28, Appendix 2in Supplemental Material) was decreased from 25 nS (basal level from Table S2) to 0 nS at arrow. Glucose induced AP firing was simulated as in Figure 3.
