This highly varied strip of epithelial cells allows for transduction of auditory signals into nerve impulses' action potential . Transduction occurs through vibrations of structures in the inner ear causing displacement of cochlear fluid and movement of hair cells at the organ of Corti to produce electrochemical signals . </P> <P> Italian anatomist Alfonso Giacomo Gaspare Corti (1822--1876) discovered the organ of Corti in 1851 . The structure evolved from the basilar papilla and is crucial for mechanotransduction in mammals . </P>

In the spiral organ pressure waves cause the displacement of
