1. The temporal discharge patterns of auditory nerve fibers in Dial-anesthetized cats were studied in response to periodic complex acoustic waveforms that evoke pitches at their fundamental frequencies. Single-formant vowels, amplitude-modulated (AM) and quasi-frequency-modulated tones. AM noise, click trains, and other complex tones were utilized. Distributions of intervals between successive spikes ("1st-order intervals") and between both successive and nonsuccessive spikes ("all-order… 

Pitch of complex tones: rate-place and interspike interval representations in the auditory nerve.

This study investigated the resolvability of harmonics of missing-fundamental complex tones in the auditory nerve (AN) of anesthetized cats at low and moderate stimulus levels and compared the effectiveness of two representations of pitch over a much wider range of F0s than in previous studies.

Temporal Coding of Periodicity Pitch in the Auditory System: An Overview

This paper outlines a taxonomy of neural pulse codes and reviews neurophysiological evidence for interspike interval-based representations for pitch and timbre in the auditory nerve and cochlear nucleus and outlines an alternative time-domain strategy for representing sensory information that complements spatially organized sensory maps.

Pitch representations in the auditory nerve: two concurrent complex tones.

Recordings from single fibers in the cat auditory nerve in response to two concurrent harmonic complex tones with missing fundamentals and equal-amplitude harmonics show that rate-place and interval-based representations allow accurate pitch perception for concurrent sounds over the entire range of human voice and cat vocalizations.

Temporal Correlates to Monaural Edge Pitch in the Distribution of Interspike Interval Statistics in the Auditory Nerve

It is found that fine temporal cues could potentially underly edge pitch, but only for a restricted range over which it is observed behaviorally, compared with the entire range of edge frequencies that generates pitch.

Spatiotemporal Representation of the Pitch of Harmonic Complex Tones in the Auditory Nerve

It is found that spatiotemporal cues to resolved harmonics are available for F0 values between 350 and 1100 Hz and that these cues are more robust than traditional rate–place cues at high stimulus levels.

Representations of the pitch of complex tones in the auditory nerve

The resolvability of harmonics of complex tones in the catauditory nerve is investigated, and the effectiveness of rate-place and interval-basedrepresentations of pitch over a much wider range of fundamental frequencies than in previous studies are compared.

Human frequency-following response: representation of pitch contours in Chinese tones

Neural Representation of Harmonic Complex Tones in Primary Auditory Cortex of the Awake Monkey

Findings indicate that population responses in A1 contain sufficient spectral and temporal information for extracting the pitch of HCTs by neurons in downstream cortical areas that receive their input from A1.

Ambiguous Pitch and the Temporal Representation of Inharmonic Iterated Rippled Noise in the Ventral Cochlear Nucleus

A temporal representation of ambiguous pitch for IRN and complex tones based on responses to the stimulus fine structure is shown, which follows the predictions of classic human behavioral experiments and provides a unifying contribution to possible neuro-temporal explanations for the pitch shift and pitch ambiguity associated with many inharmonic sounds.


We have investigated the auditory representation of vowels with low-frequency formants by recording the activity of auditorynerve fibers in anesthetized cats in response to Japanese /i/-/e/

The data indicate that responses of auditory nerve fibers contain sufficient information for extraction of the subjective pitch of AM tones by a central auditory processor which operates on temporal features of the responses.

Coding of spectral fine structure in the auditory nerve. I. Fourier analysis of period and interspike interval histograms.

The data indicate that sufficient information exists for the auditory system to determine the frequencies of narrowly spaced stimulus components from the temporal fine structure of nerve fiber's responses.

Speech coding in the auditory nerve: I. Vowel-like sounds.

Discharge patterns of auditory-nerve fibers in anesthetized cats were recorded in response to a set of nine steady-state, two-formant vowels presented at 60 and 75 dB SPL. The largest components in

Coding of temporal parameters of complex sounds by frog auditory nerve fibers.

1. Physiological recordings were made from single auditory fibers in the frog eighth nerve to determine quantitatively how the different behaviorally relevant temporal parameters (the signal

Representation of steady-state vowels in the temporal aspects of the discharge patterns of populations of auditory-nerve fibers.

A simple calculation is described which combines rate, place, and temporal information to provide a good representation of the vowels' spectra, including a clear indication of at least the first two formant frequencies.

Pitch and Cochlear Nerve Fibre Temporal Discharge Patterns

Moore (1980) has argued that neural intervals corresponding to the pitches heard should be present in the discharge patterns of cochlear fibres of CFs corresponds to the dominant region for the pitch heard, usually some 3–5 times the frequency matching the pitch.

Responses of auditory-nerve fibers to multiple-tone complexes.

Quantitative comparisons with the same fiber's responses to the nasal speech sounds indicate that the fiber's speech responses share some common features with its probe-tone responses, which indicates a breadth of frequency tuning is obtained.

Transient changes in neural discharge patterns may enhance the separation of concurrent vowels with different fundamental frequencies

Two vowels presented concurrently are better identified by human listeners when their fundamentals (F0’s) differ. Neurophysiological correlates of this phenomenon were investigated using single fiber
