Vibration hotspots reveal longitudinal funneling of sound-evoked motion in the mammalian cochlea
Abstract
Locations along the cochlea are tuned to different sound frequencies, and the individual vibration components are dynamically compressed before being converted to neural activity for further auditory processing. Here, the authors use optical coherence tomography to map sound-evoked vibrations and find a “hotspot” region with larger vibrations.
