Query: Of Mice and Chickens: Revisiting the RC Time Constant Problem   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 sharpness of tuning requires that the resonance
frequency must be lower than the RC roll-off frequency. In contrast, tuned
mechanical vibration of the inner ear is the basis of frequency selectivity of
the mammalian ear. This mechanical vibration is supported by outer hair cells
(OHC) with their electromotility based on piezoelectricity, which is driven by
the receptor potential. Thus it is also subjected to the RC time constant
problem. Association of OHCs with a system with mechanical resonance leads to
piezoelectric resonance. This resonance can nullify the membrane capacitance
and solves the RC time constant problem for OHCs.
