  • JM is up in the air about basilar matters.

    September 12, 2010

  • The basilar membrane of the inner ear contains hair cells that are frequency selective, firing only in response to a certain band of frequencies. These are stretched out across the membrane from low frequencies to high; low-frequency sounds excite hair cells on one end of the basilar membrane, medium frequency sounds excite the hair cells in the middle, and high-frequency sounds excite them at the other end. . . . Because the different tones are spread out across the surface topography of the membrane, this is called a tonotopic map.
