The last decade revealed to auditory researchers that hair cells can not only detect and process mechanical energy, but are also able to produce it. Thanks to the active hair cell, ears can produce otoacoustic emissions. This book gives the newest insights into the biophysics and physiology of individual hair cells and integral hair cell systems such as the inner ear and the lateral line organ.Contents:Some Like It Active (E de Boer)Spontaneous Otoacoustic Emissions from a Bird: A Preliminary Report (G Manley & G Taschenberger)Otoacoustic Emissions from a Nonlinear, Active Model of Cochlear Mechanics (S T Neely & L J Stover)The Mechanotransduction Channels in Cochlear Hair Cells may be Revealed by Antibodies which Recognise Other Amiloride-SensitiveChannels (C M Hackney et al)The Mechanical Implications of Variations in Hair-Bundle Shape (J O Pickles)A Molecular Motor Mediating Adaptation in Bullfrog Hair Cells (G M G Shepherd et al)Dissecting the Outer Hair Cell Feedback Loop (J F Ashmore)Alteration of Basilar Membrane Responses to Sound by Acoustic Overstimulation (M A Ruggero et al)Level Dependence of the Cellular Responses in the Guinea-Pig Cochlea (S M Khanna et al)Evidence for a Second Cochlear Map (J B Allen & P F Fahley)Time-Domain Modeling of a Nonlinear, Active Model of the Cochlea (C D Geisler et al)A Nonlinear Travelling-Wave Amplifier Model of the Cochlea (A Hubbard et al)and other papersReadership: Hearing researchers, biophysicists and biologists.
