Dissertation Available: The Transformation of Acoustic Information by Cochlear Nucleus Octopus Cells: A Modeling Study

[Kenneth L. Levy]

Hello,

My (Ken Levy) dissertation is available as a compressed postscript file for
DOS/Win and Unix (downloading directions below).  The dissertation is
entitled "The Transformation of Acoustic Information by Cochlear Nucleus
Octopus Cells: A Modeling Study."  

The cochlear nucleus is the first nuclei of the mammalian auditory
brainstem, and the octopus cell type is one of the principlal cell types.
Octopus cells respond only at the onset of a toneburst.  The dissertation
presents an analysis of a compartmental model using GENESIS that led to a
description of the underlying mechanism of the onset response of the octopus
cell.  It also includes the development, analysis and verification of the
novel, biologically-plausible model, labeled the intrinsic membrane model
(IMM), that produces accurate spike times 100-to-1000 time more efficiently
than a compartmental model.  Finally, the document covers the utilization of
the IMM to demonstrate the enhancement of the encoding of the fundamental
frequency of the vowel [i] in background noise by single-cell and ensemble
models of octopus cells.  

Comments and suggestions are welcome and encouraged!  Thank you for your
time and consideration.
