Journal ArticleDOI
Prestin-based outer hair cell motility is necessary for mammalian cochlear amplification
Peter Dallos,Xudong Wu,Mary Ann Cheatham,Jiangang Gao,Jing Zheng,Charles T. Anderson,Shuping Jia,Xiang Wang,Wendy H.Y. Cheng,Soma Sengupta,David Z.Z. He,Jian Zuo +11 more
TL;DR: This work studies a mouse model without alteration to outer hair cell and organ of Corti mechanics or to mechanoelectric transduction, but with diminished prestin function, demonstrating that prestin-based electromotility is required for cochlear amplification.
Journal ArticleDOI
Production of cochlear potentials by inner and outer hair cells
Peter Dallos,Mary Ann Cheatham +1 more
TL;DR: Cochlear microphonic and summating potential recordings were obtained from preparations where only either inner hair cells or outer hair cells could have contributed to the potentials, and a comparison suggests that outerhair cells do produce the preponderance of receptor potentials.
Journal ArticleDOI
Consequences of neural asynchrony: a case of auditory neuropathy.
Nina Kraus,Ann R. Bradlow,Mary Ann Cheatham,Jenna Cunningham,C.D. King,Dawn Burton Koch,Trent Nicol,Therese McGee,Laszlo Stein,Beverly A. Wright +9 more
TL;DR: Electrophysiological and behavioral data from a rare case of auditory neuropathy in a woman with normal hearing thresholds are presented, making it possible to separate audibility from neuropathy, and it is illustrated that optimal eighth nerve and auditory brainstem synchrony do not appear to be essential for understanding speech in quiet listening situations.
Journal ArticleDOI
Compound action potential (AP) tuning curves.
Peter Dallos,Mary Ann Cheatham +1 more
TL;DR: With a tone‐on‐tone masking procedure the compound action potential (AP), elicited by brief tone bursts of set frequency and intensity, was decreased by a constant fraction, and the frequency–intensity pairs formed by the masker generate the AP tuning curve.
Journal ArticleDOI
Positive endocochlear potential: mechanism of production by marginal cells of stria vascularis.
TL;DR: It is shown that the cell potential is more positive than the EP+, and that the ion pump is conventional Na,K-ATPase, probably in the basolateral membrane of the marginal cells of the stria vascularis.
