Nonlinear dynamics of the mammalian inner ear [PDF]
arXiv, 2015 A simple nonlinear transmission-line model of the cochlea with longitudinal coupling is introduced that can reproduce Basilar membrane response and neural tuning in the chinchilla. It is found that the middle ear has little effect on cochlear resonances, and hence conclude that the theory of coherent reflections is not applicable to the model.

Frequency dependence of prestin: Intrinsic transition rates and viscoelastic relaxation [PDF]
arXiv, 2020 Outer hair cells in the inner ear is important for the sensitivity, frequency selectivity, and dynamic range of the mammalian ear. Such a physiological role of outer hair cells is thought to be based an amplifying effect of those cells, which have mechanosensitive their hair bundles and motile cell body embedding prestin, a membrane protein with ...

Competence, specification and commitment in otic placode induction [PDF]
, 2000 The inner ear is induced from cranial ectoderm adjacent to the hindbrain. Despite almost a century of study, the molecular mechanisms of inner ear induction remain obscure. We have identified four genes expressed very early in the anlage of the inner ear,

Endogenous bone marrow stem cell mobilization in rats: Its potential role in homing and repair of damaged inner ear [PDF]
, 2015 The stem cells are widely used in the last few years in different fields of medicine, either by external transplantation or endogenous mobilization, most of these studies are still experimental on animals; few were tried on humans as in the spinal cord ...

Advances in Microfluidic Cochlea‐On‐A‐Chip
Advanced Science, EarlyView.This review systematically examines diverse cell sources for inner ear organoids and outlines stepwise induction protocols. Furthermore, it discusses current applications and prospective developments of cochlea‐on‐a‐chip technologies in areas such as deafness modeling, mechanistic studies, and drug evaluation, with particular focus on gene‐therapy drug

Development of the inner ear [PDF]
, 2015 The vertebrate inner ear is a sensory organ of exquisite design and sensitivity. It responds to sound, gravity and movement, serving both auditory (hearing) and vestibular (balance) functions.

Advanced Science, EarlyView.Data from a prospective cohort with 112 auditory brainstem implant users are analyzed. Younger age at implantation (<3 years), less severe inner‐ear malformation (common cavity, cochlear aplasia, and hypoplasia), and more intraoperative eABR evoked electrodes (≥60%) are associated with better hearing and speech outcomes.

Advanced Science, EarlyView.AAV2.7m8 serotype combined with the gfaABC1D promoter targets infection of supporting cells (SCs). AAV2.7m8‐gfaABC1D‐Gjb2 administration to mice results in excessive immune responses. The combination of AAV2.7m8‐gfaABC1D‐Gjb2 with dexamethasone (DEX) shows a synergistic effect and enhances the gene therapy effect in a conditional Cx26 null mice model ...

Towards a complete 3D morphable model of the human head [PDF]
arXiv, 2019 Three-dimensional Morphable Models (3DMMs) are powerful statistical tools for representing the 3D shapes and textures of an object class. Here we present the most complete 3DMM of the human head to date that includes face, cranium, ears, eyes, teeth and tongue.

3D Printed Ear Canal Model [PDF]
, 2017 A multi-material ear canal model was designed and created from CT scans of an actual patient. This ear canal model serves as a training model for trainees, surgeons and doctors to develop a better understanding of the anatomy and physiology of the ear ...
