  • Title: Frequency tuning of mechanical responses in the mammalian cochlea.
    Author: Robles L, Alcayaga C.
    Journal: Biol Res; 1996; 29(3):325-31. PubMed ID: 9278704.
    Abstract:
    The search for mechanisms responsible for the high sensitivity and sharp frequency tuning of first-order auditory neurons has produced surprising results. The cochlea, the mammalian auditory receptor, responds to acoustic stimuli with a sharply frequency tuned, nonlinear vibration that enhances low level stimuli, but generates appreciable distortion. This highly sensitive mechanical response is achieved by an electro-mechanical feedback process in which outer hair cells reinforce cochlear motion at low stimulus intensities.
