Parameters for fitted curves shown in Fig. 9, which show the change in the cutoff frequency of the temporal modulation transfer functions (for two methods of analysis) and equivalent rectangular bandwidth (ERB; Hartmann 1998) as a function of biophysical parameter value

Columns are the inflection point of the Boltzman curve normalized to the mean biophysical parameter value; the minimum to maximum range of the function; the slope and the R² value of the curve fit. The biophysical parameters are the ahp conductances (ḡ_ahp) and the Ca²⁺ removal times (τ_removal) for pools 1 and 2
