Chloride binding to prestin does not influence very high-frequency complex nonlinear capacitance (cNLC) in the mouse outer hair cell

This study shows chloride binding does not affect very high-frequency nonlinear capacitance in mouse outer hair cells, suggesting mechanical loads, not anion interactions, govern high-frequency prestin function.

Ultrasonic measures of prestin (SLC26a5) charge movements in membrane patches.

This study uses megahertz sampling to measure prestin charge movements in the ultrasonic range, finding a lower frequency roll-off and confirming a cut-off frequency near 19 kHz.

Phase tracking algorithms detect both real and imaginary components of outer hair cell nonlinear membrane capacitance that exhibits dielectric loss.

The paper demonstrates that phase tracking algorithms can detect dielectric loss in outer hair cell membrane capacitance, validating previous measurements of NLC frequency response.

Calcium induced calcium release in proximity to hair cell BK channels revealed by PKA activation

The paper shows that PKA activation enhances BK currents in chicken hair cells by increasing Ca2+ concentrations via CICR near BK channels.
