Connected Hearing

Construction of complex structures often involves a surprising amount of dismantling and recycling, as temporary structures are erected to enable permanent features to be built. This is how synaptic ribbons develop in the inner ear, according to new research. Synaptic ribbons are tiny protein structures at the junction between sensory inner hair cells and auditory neurons, helping transmit sound information rapidly to nerves. To study how these ribbons assemble, a team developed a technique for live-imaging inner ear cells from young mice (pictured, cross-sections of the organ of Corti, a sensory structure in the ear). They saw the ribbon components constantly merge, split apart, and move between developing synapses in a dynamic dance of construction during development. Missed connections can affect hearing like loose wires in a speaker, so these findings that improve our overall understanding of how the auditory system develops could ultimately inform research into congenital hearing disorders.
