A simplified physiological model of rate-level functions of auditory-nerve fibers
2021, Hearing ResearchCitation Excerpt :This change in shape is reminiscent of the transition from flat-saturating to sloping-saturating rate-level functions with decreasing spontaneous rate, as described in the literature (e.g., Sachs and Abbas, 1974; Winter et al., 1990). According to the rate-additivity model (Sachs and Abbas, 1974; Sachs et al., 1989; Yates, 1990; Yates et al., 1990; Müller and Robertson, 1991a), a perfect sigmoid should describe rate-level functions at frequencies far below CF, where the basilar membrane is linear, irrespective of ANF spontaneous rate. It should also describe rate-level functions at CF for ANFs having high spontaneous rates, because these ANFs have low thresholds and narrow dynamic ranges and rate saturation is reached at stimulus levels where the basilar membrane still operates in its linear range.
Input-output curves of low and high spontaneous rate auditory nerve fibers are exponential near threshold
2018, Hearing ResearchCitation Excerpt :The present data provide actual experimental, quantitative evidence for the relevance of that assumption, as will be shown below. Rate-level curves have been modeled such that the effective rate (average rate minus spontaneous rate) more or less mimics the magnitude of basilar membrane displacement (Geisler, 1990; Sachs et al., 1989; Yates et al., 1990). In these applications, SR is handled as a separate quantity that represents an intrinsic property of individual ANFs.
