Study: Hearing develops in tandem with form and function

(Oregon Health & Science University) New research reveals a key insight into the development of hair bundles, the intricately complex assemblies in the inner ear responsible for hearing. Researchers found that stereocilia, roughly 100 of which are assembled into a hair bundle, widened simultaneously with the onset of mechanotransduction. The stereocilia only elongated to their mature lengths after transduction had been established.
