Alfonso Giacomo Gaspare Corti discovered that inside the Cochlea of the Inner ear lies within the cochlear duct an organ wound up in a spiral and firmly attached to the Basilar membrane. This organ turns out to be basic receptor organ for Human hearing, where the nervous endings of auditory nerves lie, and are excited by Mechanotransduction taking place within the organ.
