A reliable method to investigate outer hair cell (OHC) motile responses, including electromotility, slow motility and bending, is described. OHC motility is elicited by stimulation with an external alternating electrical field, and the method takes advantage of high-speed image recording, LED-based illumination, and last generation image analysis software.

House Ear Institute-Organ of Corti 1 (HEI-OC1) is one of the few mouse auditory cell lines currently available for research purposes. This protocol describes how to work with HEI-OC1 cells to investigate the cytotoxic effects of pharmacological drugs as well as functional properties of inner ear proteins.
