    Talk Title: How Cochlear Biomechanics Tunes Mammalian Hearing

    Abstract: The exquisite sensitivity and frequency discrimination of mammalian hearing derive from forces generated by outer hair cells (OHCs) within the auditory portion of the inner ear, the cochlea. These forces amplify the sound-induced vibrations within the tissues of the cochlea to enhance quiet sounds and sharpen frequency tuning. Our group has pioneered the technique of using optical coherence tomography to measure sound-induced vibrations within the mammalian cochlea without opening the bone that surrounds it, thus minimizing artifacts. Furthermore, we study transgenic mice with targeted mutations that affect different biomechanical aspects of the cochlea to localize the underlying processes necessary for normal hearing. The goal of this work is to understand the fundamental biomechanical changes that underlie progressive hearing loss and to develop treatments to overcome them.
