Two dimensional vibrations of the guinea pig apex organ of Corti measured in vivo using phase sensitive Fourier domain optical coherence tomography
2015
In this study, we measure the in vivo apical-turn vibrations of the guinea pig organ of Corti in both axial and radial
directions using phase-sensitive Fourier domain optical coherence tomography. The apical turn in guinea pig cochlea has
best frequencies around 100 – 500 Hz which are relevant for human speech. Prior measurements of vibrations in the
guinea pig apex involved opening the otic capsule, which has been questioned on the basis of the resulting changes to
cochlear hydrodynamics. Here this limitation is overcome by measuring the vibrations through bone without opening the
otic capsule. Furthermore, we have significantly reduced the surgery needed to access the guinea pig apex in the axial
direction by introducing a miniature mirror inside the bulla. The method and preliminary data are discussed in this
article.
