Optical manipulation of mechano-receptors. (A) Top: Schematic of a mechanical wave (blue) traveling through zebrafish inner ear and vibrating sensory organs (black arrows). Bottom: Schematic of OT manipulating selectively one sensory organ within the inner ear and producing a similar vibration to a mechanical wave. Reproduced from Favre-Bulle et al.
