  • Title: A micromechanical contribution to cochlear tuning and tonotopic organization.
    Author: Holton T, Hudspeth AJ.
    Journal: Science; 1983 Nov 04; 222(4623):508-10. PubMed ID: 6623089.
    Abstract:
    The response properties of hair cells and nerve fibers in the alligator lizard cochlea are frequency selective and tonotopically organized with longitudinal position in the organ. The lengths of the hair-cell hair bundles also vary monotonically with longitudinal position. In this study, quantitative measurements were made of the motion of individual hair bundles in an excised preparation of the cochlea stimulated at auditory frequencies. The angular displacement of hair bundles is frequency selective and tonotopically organized, demonstrating the existence of a micromechanical tuning mechanism.
