Default model parameters.

Default model parameters used in the manuscript unless mentioned otherwise. Parameter values are based on the indicated literature references ( indicates adjusted parameters), see also reference [7] for a discussion of the parameters introduced there. All glycolytic parameters are taken without modification from reference [11], where a discussion of their values based on experimental data can be found. HERG channel conductance, , was set to zero in the present work to investigate whether SK-channels can substitute for HERG channels, e.g., in driving bursting. Based on [47], the previous version of the model [7] used nS/pF. The conclusions presented here are not sensitive to whether or not HERG currents are included.
