Steady state and tau equations for ionic channels.

Voltage sensitive calcium channels are not listed because they use the same parameters and equations as Wolf et al. [16], but using m instead of mx for CaL1.2, CaN, CaR, and CaT. V = voltage, scale = value by which time constants were scaled during tuning, [Ca] = calcium concentration, EC50 = half activation for calcium dependence, F = Faraday constant, R = Ideal Gas constant. Equations: sigmoid = rate/(1+(exp ((V−vhalf)/slope))), exp = exp((V−vhalf)/slope), SK_eqn = (([Ca]/EC50)∧5.4)/(1+([Ca]/EC50)∧5.4), BK_eqn1 = (B*[Ca])/([Ca]+K*(exp((2VDF)/(RT)), BK_eqn2 = B/(1+[Ca]/(K*(exp((2VDF)/(RT)).
