Getting to the bottom of directional hearing in fish
The human nervous system locates the origin of a sound in space by comparing the difference in time and in amplitude of the sound waves arriving at each ear. The same is true for other terrestrial vertebrates. Although directional hearing in fish has been confirmed behaviourally, the mechanisms are unknown. The EU-funded GlassBrain project will exploit its recent identification of a tiny transparent fish with behaviours linked to sound production to answer these open questions. The team will combine in vivo imaging techniques to reconstruct the entire acoustic processing chain, including mechanical stimulus of the inner ear, neuronal activity of the sensory epithelia and whole-brain sensory integration, all with single-cell resolution.
