}The perceptual significance of the cochlear amplifier was evaluated by predicting level-discrimination performance based on stochastic auditory-nerve (AN) activity. Performance was calculated for three models of processing: the optimal all-information processor (based on discharge times), the optimal rate-place processor (based on discharge counts), and a monaural coincidence-based processor that uses a non-optimal combination of rate and temporal information. An analytical AN model included…

It is shown that performance predicted from use of all rate information degrades significantly as level increases above low–medium levels, inconsistent with Weber’s Law.

Phase Locking of Auditory-Nerve Fibers Reveals Stereotyped Distortions and an Exponential Transfer Function with a Level-Dependent Slope
- BiologyThe Journal of Neuroscience

Intriguingly, period histograms from phase-locked ANF responses to low-frequency tones exhibit spike-rate and temporal asymmetries, but otherwise retain an approximately sinusoidal shape as stimulus level increases, even beyond the level at which the mean spike rate saturates.
Coincidence detection in the cochlear nucleus: implications for the coding of pitch
- Biology
- 2011
It is found that, in response to harmonic complex tones, cross-frequency CD cells and some CN units (primary-like-with-notch and choppers) maintained robust rate cues at high levels compared to AN fibers, suggesting that at least some CN neurons extend the dynamic range of rate representations of pitch beyond that found in AN fibers.

Predictions of formant-frequency discrimination in noise based on model auditory-nerve responses.
- PsychologyThe Journal of the Acoustical Society of America
- 2006
The relative timing of action potentials across auditory-nerve fibers tuned to different frequencies was not the aspect of the temporal information that produced the trends in formant-frequency discrimination thresholds, so combined temporal and rate information for a small population of model fibers tuned near the formant frequency was most successful in replicating the trends reported in behavioral data.
Across-Channel Timing Differences as a Potential Code for the Frequency of Pure Tones
- PhysicsJournal of the Association for Research in Otolaryngology
- 2011
Although the use of across-channel timing cues provides an a priori attractive and plausible means of encoding pitch, many of the most obvious metrics for using that cue produce pitch estimates that are strongly influenced by the overall level and therefore are unlikely to provide a straightforward means for encoding the pitch of pure tones.

Results of this analysis show that rate-place predictions for frequency discrimination are inconsistent with human performance in the dependence on frequency for high frequencies and that there is significant temporal information in the AN up to at least 10 kHz.

The findings suggest that overshoot in normal and hearing-impaired listeners is mediated by some form of dynamic range adaptation other than what is observed in the auditory nerve of anesthetized animals.

This article shows how many different phenomena can be explained as consequences of this nonlinearity, including the "excess" masking produced when 2 nonsimultaneous maskers are combined, the nonlinear growth of forward masking with masker level, and the influence of component phase on the effectiveness of complex forward maskers.

Auditory nerve fibers synchronize or phase-lock to low-frequency tones and transmit this temporal information to cells in the anteroventral cochlear nucleus of the AVCN, and it is found that most TB axons exhibited enhanced synchronization compared with AN fibers.

A quantitative model for describing data from modulation-detection and modulation-masking experiments is presented, which proposes that the typical low-pass characteristic of the temporal modulation transfer function observed with wide-band noise carriers is not due to "sluggishness" in the auditory system, but can instead be understood in terms of the interaction between modulation filters and the inherent fluctuations in the carrier.
