2007 journal article

Deafness alters auditory nerve fibre responses to cochlear implant stimulation

EUROPEAN JOURNAL OF NEUROSCIENCE, 26(2), 510–522.

By: D. Sly *, L. Heffer*, M. White n, R. Shepherd *, M. Birch*, R. Minter*, N. Nelson*, A. Wise *, . Stephen J. O'Leary

author keywords: electrical stimulation; guinea pig; hearing loss; neurodegeneration; spiral ganglion
MeSH headings : Acoustic Stimulation; Animals; Auditory Threshold / physiology; Axons / physiology; Cochlear Implants; Cochlear Nerve / physiopathology; Deafness / physiopathology; Electric Stimulation; Electrophysiology; Evoked Potentials, Auditory, Brain Stem / physiology; Female; Guinea Pigs; Male; Nerve Fibers / physiology; Neurons / physiology; Spiral Ganglion / cytology; Spiral Ganglion / physiology
TL;DR: The results suggest that changes in the function of individual auditory nerve fibres after deafness may affect clinical responses during high‐rate stimulation such as that used in contemporary speech processing strategies, but not during lower rate stimulation suchAs that used to record evoked potentials.

2000 journal article

Renewal-process approximation of a stochastic threshold model for electrical neural stimulation

JOURNAL OF COMPUTATIONAL NEUROSCIENCE, 9(2), 119–132.

By: I. Bruce *, L. Irlicht*, M. White n, . SJ O'Leary & G. Clark *

author keywords: functional electrical stimulation; stochastic model; renewal process; refractory effects; auditory nerve
MeSH headings : Action Potentials / physiology; Cochlear Implants / standards; Cochlear Nerve / cytology; Cochlear Nerve / physiology; Electric Stimulation / methods; Models, Neurological; Monte Carlo Method; Stochastic Processes
TL;DR: An analytical approximation is derived for the single-pulse model, which is then extended to describe the pulse-train model in the case of evenly timed, uniform pulses, which provides an accurate and computationally efficient model of electrical stimulation of single auditory nerve fibers by a cochlear implant that may be extended to other forms of electrical neural stimulation.

2000 journal article

Using an artificial neural network to detect activations during ventricular fibrillation

COMPUTERS AND BIOMEDICAL RESEARCH, 33(1), 43–58.

By: M. Young n, S. Blanchard n, M. White n, E. Johnson, W. Smith* & R. Ideker*

MeSH headings : Diagnosis, Computer-Assisted; Electrocardiography / statistics & numerical data; Electrophysiology; Humans; Neural Networks, Computer; Sensitivity and Specificity; Ventricular Fibrillation / diagnosis; Ventricular Fibrillation / physiopathology
TL;DR: Staged training, a new method that uses different sets of training examples in different stages, was used to improve the ability of the artificial neural networks to detect activation and they were able to correctly classify more than 92% of new test examples. (via Semantic Scholar)

1999 journal article

A stochastic model of the electrically stimulated auditory nerve: Pulse-train response

IEEE TRANSACTIONS ON BIOMEDICAL ENGINEERING, 46(6), 630–637.

By: I. Bruce *, L. Irlicht*, M. White n, . SJ O'Leary, S. Dynes *, E. Javel*, G. Clark *

author keywords: auditory nerve; cochlear implant; functional electrical stimulation; pulse-train response; population response; refractory effect; renewal process; sensory prosthesis; stochastic model
MeSH headings : Analysis of Variance; Animals; Auditory Threshold; Cats; Electric Stimulation; Least-Squares Analysis; Models, Neurological; Predictive Value of Tests; Refractory Period, Electrophysiological / physiology; Reproducibility of Results; Sensitivity and Specificity; Stochastic Processes; Vestibulocochlear Nerve / physiology
TL;DR: 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.
