Evidence and Implications of Inhomogeneity in Tectorial Membrane Elasticity
TL;DR: This work subdivide the tectorial membrane into three longitudinal regions and five radial zones and map the shear modulus of the TM using atomic force microscopy, and presents evidence that the TM elasticity varies radially, after the distribution of type A collagen fibrils.
Journal ArticleDOI
Evidence of tectorial membrane radial motion in a propagating mode of a complex cochlear model
TL;DR: This work extends the frequency range of their previous hybrid analytical-finite-element approach to model the basal as well as apical regions of the guinea pig cochlea and solves the fluid-solid interaction eigenvalue problem for the axial wavenumber, fluid pressure, and vibratory relative motions of the cochlear partition as a function of frequency.
Journal ArticleDOI
Effects of coiling on the micromechanics of the mammalian cochlea
TL;DR: A recently developed hybrid analytical/numerical micromechanics model is extended to include curvature effects, which were previously ignored, and it is found that the curvature of the cochlear geometry has an important functional significance; at the apex, it greatly increases the shear gain of the joint partition, which is a measure of the bending efficiency of the outer hair cell stereocilia.
Journal ArticleDOI
Radial Structure of Traveling Waves in the Inner Ear
Hongxue Cai,Richard S. Chadwick +1 more
TL;DR: A hybrid approach for modeling the cochlea is developed, in which the WKB method determine the axial propagation of waves and restrict the numerics to transverse planes, where the interaction between the BM, TM, OC, and the co chlear fluid is computed to find the complex-valued wavenumber-frequency relation and vibrational modes.
Journal ArticleDOI
Motion Analysis in the Hemicochlea
TL;DR: This work forms a well-posed problem for the gerbil hemicochlea preparation by introducing an in-plane incompressibility constraint, and shows that local brightness is also conserved, using a Lagrangian description of the conservation equations.
