Multiple Modes of Motion for the Effectiveness of Outer Hair Cells at High Frequencies
Kuni H. Iwasa
Outer hair cells (OHCs) are essential for the sensitivity and frequency specificity of the mammalian ear. To perform this function, OHCs need to amplify the motion of the basilar m…
Of Mice and Chickens: Revisiting the RC Time Constant Problem
Kuni H. Iwasa
Avian hair cells depend on electrical resonance for frequency selectivity. The upper bound of the frequency range is limited by the RC time constant of hair cells because the sharp…
Not so presto? Outcomes of sluggish prestin in outer hair cells
Kuni H. Iwasa
Prestin (SLC26A5), a protein essential for the sensitivity of the mammalian ear, was so named from \emph{presto}. The assumption was that this membrane protein supports fast moveme…
Kinetic Membrane Model of Outer Hair Cells I: Motile Elements with Two Conformational States
Kuni H. Iwasa
The effectiveness of outer hair cells (OHCs) in amplifying the motion of the organ of Corti, and thereby contributing to the sensitivity of mammalian hearing, depends on the mechan…
Negative membrane capacitance of outer hair cells: electromechanical coupling near resonance
Kuni H Iwasa
The ability of the mammalian ear in processing high frequency sounds, up to 100 kHz, is based on the capability of outer hair cells (OHCs) responding to stimulation at high f…
Energy output from a single outer hair cell
Kuni H Iwasa
Electromotility of outer hair cells (OHCs) has been extensively studied with in vitro experiments because of its physiological significance in the cochlear amplifier, which provide…
The avian tectorial membrane: Why is it tapered?
Kuni H. Iwasa, Anthony J. Ricci
While the mammalian- and the avian inner ears have well defined tonotopic organizations as well as hair cells specialized for motile and sensing roles, the structural organization…
