Development of frequency tuning in the auditory periphery.
The peripheral auditory organ, the cochlea, acts as a spectral analyzer resolving the frequency components of sound. During development the cochlea first responds to loud low-frequency sounds, and only gradually acquires the adult pattern of increased sensitivity and an expanded high-frequency range. This evolution of function may result in part from the gradual maturation of hair cell properties.
