Roles of supporting cells in the maintenance and regeneration of the damaged inner ear: A literature review

open access: yesJournal of Otology
The inner ear sensory epithelium consists of two major types of cells: hair cells (HCs) and supporting cells (SCs). Critical functions of HCs in the perception of mechanical stimulation and mechanosensory transduction have long been elucidated.

Role of Dach1 revealed using a novel inner ear-specific Dach1-knockdown mouse model

open access: yesBiology Open, 2019
The Dach1 gene is expressed in the inner ear of normal mouse embryos in the area that differentiates into the cochlear stria vascularis (SV). We hypothesised that Dach1 downregulation in the inner ear would lead to SV dysplasia.

The Active Traveling Wave in the Cochlea [PDF]

open access: yes, 2003
A sound stimulus entering the inner ear excites a deformation of the basilar membrane which travels along the cochlea towards the apex. It is well established that this wave-like disturbance is amplified by an active system.

Waveguide Photoactuators: Materials, Fabrication, and Applications

open access: yesAdvanced Robotics Research, EarlyView.
Waveguide photoactuators convert guided light into mechanical motion. Their tethered‐flexible design enables minimally invasive surgery and confined‐space robotics. This review aims to guide materials selection, device design, and system integration, accelerating the transition of waveguide photoactuators from laboratory prototypes to versatile ...

Inner Ear Therapeutics: An Overview of Middle Ear Delivery

open access: yesFrontiers in Cellular Neuroscience, 2019
There are a variety of methods to access the inner ear and many of these methods depend on utilizing the middle ear as a portal. In this approach the middle ear can be used as a passive receptacle, as part of an active drug delivery system, or simply as ...

Interactions of Interaural Time and Level Differences in Spatial Hearing with Cochlear Implants

open access: yesAdvanced Science, EarlyView.
Differences in timing (ΔT) are weighted heavily compared to differences in loudness (ΔL) in binaural hearing with cochlear implants. Abstract Normally hearing humans can localize sound sources quite accurately, with minimum audible angles as small as 1°. To achieve this, these auditory pathways combine information from multiple acoustic cues, including

Sufu and Gli3 repressor mediate the temporal basal-to-apical progression of hair cell differentiation in mammalian cochleae [PDF]

open access: yes, 2014
Poster presentation - Theme 3: Development & stem cellsThe Sonic Hedgehog pathway plays important roles in mammalian inner ear development. Mutations of Shh, Smo and Gli3 lead to severe defects in mouse inner ear morphogenesis.

Plastin 1 widens stereocilia by transforming actin filament packing from hexagonal to liquid [PDF]

open access: yes, 2016
With their essential role in inner-ear function, stereocilia of sensory hair cells demonstrate the importance of cellular actin protrusions. Actin packing in stereocilia is mediated by crosslinkers of the plastin, fascin, and espin families.
