Figure 5. Coexpressing the A conductance with the T conductance was analogous to the presence of leak channels in terms of modulating IRD measurements.

A, voltage traces in response to chirp stimulus in the presence of T conductance alone (upper trace), and in the presence of both T and A conductances (lower trace). B, plots showing f_R as a function of maximal A conductance (), for various values of maximal T conductance (). C, impedance phase profiles (ZPP), derived from traces in A, in the presence of T conductance alone (= 0), and in the presence of both T and A conductances (= 50 mS cm⁻²). D, plots showing f_R as a function of half-maximal activation voltage of the A conductance, for various values of . E, ZPPs in the presence of both T and A conductances, for various values of the half-maximal activation voltage of the A conductance. F, plots showing f_R as a function of half-maximal inactivation voltage of the A conductance, for various values of . G, ZPPs in the presence of both T and A conductances, for various values of the half-maximal inactivation voltage of the A conductance. H, plots showing f_R as a function of the activation time constants of the A conductance, for various values of . I, ZPPs in the presence of both T and A conductances, for various values of the activation time constants of the A conductance. The same maximal T conductance (= 0.5 mS cm⁻²) was used for simulation results shown in D–I. Also see Fig. S15 and Table 6 for a complete analysis of the interactions of these two channels in determining neuronal IRD.
