Inwardly rectifying K+ currents in inner and outer hair cells (IHCs, OHCs) were studied during postnatal development of the mouse cochlea. Hyperpolarizing steps from a holding potential of –64 mV induced a rapidly activating current in both cell types. This current showed strong inward rectification around the K+ equilibrium potential and, at potentials negative to –130 mV, partial inactivation. The activation range varied with extracellular K+ concentration. External application of Ba2+ and Cs… CONTINUE READING
