Webb17 jan. 2024 · In 1985, Bill Brownell and colleagues published the remarkable observation that cochlear outer hair cells (OHCs) express voltage-driven mechanical motion: electromotility. They proposed OHC electromotility as the mechanism for the elusive “cochlear amplifier” required to explain the sensitivity of mammalian hearing. WebbFor the scientifically minded: This outer hair cell gets thinner when it gets longer and fatter when it gets shorter. Measuring up these changes indicates that the cell volume stays constant. This supports the idea that the ‘motor’ is a molecule whose job it is to change membrane area.
