A stochastic model of the electrically stimulated auditory nerve: single-pulse response
A simple and computationally efficient stochastic model of single-fiber response to single biphasic electrical pulses is presented, based on a deterministic threshold model of action potential generation.

Normalization of stimulus intensity to the dynamic range of hearing resulted in Weber functions with similar negative slopes for electric and acoustic stimulation, corresponding to an 8-dB average improvement in Weber fractions across the dynamicrange.

Electrophysiological and cytoarchitectonic evidence suggest that this belt of cortex in the owl monkey is composed of at least three and possibly four separate auditory fields, which are generally less responsive to acoustic stimulation and the frequency organization is more complex than in AI or R.
Responses of Cat Auditory Nerve Fibers to Biphasic Electrical Current Pulses
Discharge patterns of single auditory nerve fibers were recorded from normal-hearing cats implanted with a 12-band intracochlear electrode array to determine the cochlear positions of the fibers.

A stochastic model of the electrically stimulated auditory nerve: pulse-train response
The single-pulse model of the companion paper is extended to describe responses to pulse trains by introducing a phenomenological refractory mechanism and it is shown that both the shape and slope of mean discharge rate curves are better predicted by the stochastic model than by the deterministic model.

Acoustic and Electrical Encoding of Temporal Information
- E. Javel
- Physics, Biology
This work has shown that strikingly close correspondences exist between phase-locked activity patterns in peripheral auditory nuclei of animals and perceptual performance of human listeners on certain tasks, there is still no clear evidence that the human brain actually bases perceptual decisions on temporally encoded information.
Long-term adaptation in cat auditory-nerve fiber responses.

The data suggest that long-term adaptation may occur either when neurotransmitter utilization at inner hair cell synapses exceeds the rate at which it is replenished from global stores or uptake mechanisms, or which metabolic resources influencing neurotransmitter release become depleted.
