Comparison of fit results obtained from the current model and those obtained by Peterson and Heil (2019) for a representative mid-CF, low-SR ANF (A7-U10-R2; CF = 1.2 kHz; SR = 0.1 spikes/s) in response to CF tones from 42 to 90 dB SPL. A, Period histograms of event rates (colored by stimulus level) and corresponding fits from the current model (white lines). The best-fitting parameters for the current model are M0 = 0.25, b = 512.72 Pa−1, fc = 0.75 kHz, and D = 20.89. B, The overall transfer functions relating the instantaneous stimulus pressure to the instantaneous rate of release events. C, The slope factor (overall B) as a function of the stimulus level. D, The scale factor (overall A) as a function of the stimulus level. E–H, Corresponding results from the Peterson and Heil (2019) model.
