TLDR
An unexpected finding was that the initial discharge at threshold is a low probability event that can be evoked, except for a short initial time period, by any stimulus cycle throughout the tone duration.Abstract:
1. Latency behavior of neurons in the cochlear nuclear complex was studied in 45 barbiturate-anesthetized cats. Stimuli were tonal bursts usually 50-500 ms in duration. 2. Latency of the initial discharge is a systematic function of the frequency and intensity of the tone for a large class of neurons which are termed latency precedence cells. Most cells in the anteroventral cochlear nucleus and many neurons in the anterior division of the posteroventral nucleus belong to this class. Unless otherwise stated, all findings pertain to this cell group. 3. There is usually a correspondence between the discharge rate of a given neuron and the latency of the initial discharge, the higher the discharge rate the shorter the latency. Hence, for any intensity level evoking less than saturation discharge rate, initial discharge latency tends to be ‘shortest for best-frequency stimuli and lengthens systematically as the stimulating frequency departs in either direction from best frequency. However, for some cells, intense stimuli above best frequency evoke initial discharges at latencies which are similar to those produced by best-frequency stimuli. 4. An unexpected finding was that the initial discharge at threshold is a low probability event that can be evoked, except for a short initial time period, by any stimulus cycle throughout the tone duration. Hence, tone duration is a parameter in determining the threshold. Within limits, the longer theread more

Similarity of Traveling-Wave Delays in the Hearing Organs of Humans and Other Tetrapods
TL;DR: The estimated in vivo basilar-membrane delays in humans are similar to delays in the hearing organs of other tetrapods, including those in which basilar membranes do not sustain traveling waves or that lack basilar membrane vibrations altogether.

Regularity and latency of units in ventral cochlear nucleus: implications for unit classification and generation of response properties
TL;DR: The results for chopper units suggest a model for stellate cells in which a regularly firing action potential generator is driven by the summation of the AN inputs to the cell, where the summations is low-pass filtered by the membrane capacitance of the cell.

Auditory cortical onset responses revisited: I. First-spike timing
TL;DR: The timing of spikes of single neurons in the primary auditory cortex of barbiturate-anesthetized cats to the onsets of tone bursts is analyzed to suggest a peripheral origin of S and a peripheral establishment of latency-acceleration/rate of change of peak pressure functions.

Theory of Temporal Auditory Summation
TL;DR: In this article, a theory of temporal auditory summation is developed and applied to the threshold of audibility for various temporal patterns of pulses and sinusoidal vibrations, based on the assumption of an exponential decay of neural excitation.
