Mechanical Response of the Outer Hair Cell Region of an Isolated Guinea Pig Cochlea in Vitro
The mechanical response of the guinea pig cochlea was measured utilizing a combination of an optical sectioning microscope (Koester, 1980) and a heterodyne interferometer (Willemin, Dandliker & Khanna, 1988). The optical sectioning microscope allowed visualization of the cochlear structure through the intact Reissner’s membrane. Individual Hensen’s cells could always be visualized. In favorable preparations individual rows of outer hair cells, pillar cells, inner hair cells and many other cochlear structures could also be seen.
