Neuronal population model of globular bushy cells covering unit-to-unit variability

A: PSTHs of the AN (top, red) and GBC (bottom, blue) models driven by 100-Hz SAM tone at 20 dB SPL (see Table 1 for the parameter values used). Characteristic frequency (CF) of the models is 7000 Hz. B-C: Level-dependent spiking rates (B) and envelope phase-locking (C) of the same AN (red) and GBC (blue) models as in A. Filled circles in B-C indicate the condition for which the model showed the maximum VS. D-F: CF-dependent envelope phase-locking of the PLN model population (D: blue curves), OnL model population (E: green curves), and the AN model (F: red curve) to 100-Hz SAM tone at 20 dB SPL. In D-E, the maximum VS was computed for sound intensities between 10 and 45 dB SPL (5 dB steps). Triangles in D and E indicate empirical single-unit data of presumed GBCs, and hollow diamonds in F show AN fiber data recorded in cats [66].
