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

A ratchet mechanism for amplification in low-frequency mammalian hearing
The sensitivity and frequency selectivity of hearing result from tuned amplification by an active process in the mechanoreceptive hair cells. In most vertebrates the active process stems from the active motility of hair bundles.

Drug-induced stress granule formation protects sensory hair cells in mouse cochlear explants during ototoxicity [PDF]
Stress granules regulate RNA translation during cellular stress, a mechanism that is generally presumed to be protective, since stress granule dysregulation caused by mutation or ageing is associated with neurodegenerative disease.

Proteomic Analysis Reveals the Composition of Glutamatergic Organelles of Auditory Inner Hair Cells
In the ear, inner hair cells (IHCs) employ sophisticated glutamatergic ribbon synapses with afferent neurons to transmit auditory information to the brain. The presynaptic machinery responsible for neurotransmitter release in IHC synapses includes proteins such as the multi-C2-domain protein otoferlin and the vesicular glutamate transporter 3 (VGluT3).

Correct Timing of Proliferation and Differentiation is Necessary for Normal Inner Ear Development and Auditory Hair Cell Viability [PDF]
Background: Hearing restoration through hair cell regeneration will require revealing the dynamic interactions between proliferation and differentiation during development to avoid the limited viability of regenerated hair cells. Pax2‐Cre N‐Myc conditional knockout (CKO) mice highlighted the need of N‐Myc for proper neurosensory development and ...

This study establishes a robust and reproducible protocol for generating human otic neuronal spheroids (hONS) from cryopreserved hPSC‐derived pre‐placodal ectoderm cells. These hONS further differentiate into functional SGN‐like neurons, which extend neurite projections toward both murine hair cells and human cortical organoids, thereby forming ...

Insights into the regulation of hearing regeneration
Our perception of sound is mediated by sound-sensitive hair cells in the inner ear, located in a specialized neuro-epithelium that transmits information to the auditory cortex via the auditory pathway.

Absence of plastin 1 causes abnormal maintenance of hair cell stereocilia and a moderate form of hearing loss in mice [PDF]
Hearing relies on the mechanosensory inner and outer hair cells (OHCs) of the organ of Corti, which convert mechanical deflections of their actin-rich stereociliary bundles into electrochemical signals. Several actin-associated proteins are essential for

This work shows, for the first time, that the stereocilia membrane in cochlear hair cells is dynamically regulated by the mechanotransduction channel to impact the membrane mechanical properties. This work provides direct evidence that the opening and closing associated with the MET channel is regulating the membrane viscosity suggesting that the MET ...

Acoustically evoked potentials in two cephalopods inferred using the auditory brainstem response (ABR) approach [PDF]
It is still a matter of debate whether cephalopods can detect sound frequencies above 400 Hz. So far there is no proof for the detection of underwater sound above 400 Hz via a physiological approach.
