Table 1.

Parameter values of ionic currents described by Eqs. (2)–(6). Units for time constant parameters a, b, c, d, e, f vary and are inferred from the functions τ_i, each of which is described by ${\tau }_1(V)=c·exp[-{(\frac{v-a}{b})}^2]+d$ and ${\tau }_2(V)=e·{[exp(\frac{a+v}{b})+exp(\frac{c+v}{d})]}^{-1}+f$.
