Ionic effect on ATP-modifying OHC electromotility-associated NLC. Vpk shifts for the application of 36 μM ATP under different ionic conditions were normalized to the Vpk shift under the normal condition (K pipette). Cs pip Cs+ to replace K+ in the intracellular solution, BAPTA BAPTA-buffered pipette, Cs-ES the Cs-based extracellular solution in which Na+ and K+ were replaced with Cs+, No Ca Ca++-free extracellular solution that contains 0 mM Ca++ and 10 mM EGTA. Error bars represent SE. The asterisk indicates a statistically significant difference (P<0.001, ANOVA)
