Otoacoustic emission measurements: a test–retest reliability study

The Egyptian Journal of Otolaryngology, 2023
Objectives Otoacoustic emissions (OAEs) are an important part of the audiological test battery and have many clinical uses. This study aims to determine the amplitude changes in the test–retest condition of distortion product otoacoustic emissions ...

Visualization of the Spiral Ganglion Neuron in Vivo Using a Novel 177Lu Nuclear Molecule Label

Advanced Science, EarlyView.
The study developed and validated a radionuclide‐labeled anti‐VGLUT1 antibody probe for the first nuclear imaging of cochlear spiral ganglion neurons (SGNs) in vivo. This approach may provide aid in screening candidates suitable for CI surgery by quantifying the number of surviving SGNs, and predicting the potential for postoperative hearing ...

A convolutional neural-network model of human cochlear mechanics and filter tuning for real-time applications

, 2020
Auditory models are commonly used as feature extractors for automatic speech-recognition systems or as front-ends for robotics, machine-hearing and hearing-aid applications. Although auditory models can capture the biophysical and nonlinear properties of

The Auditory Nerve Overlapped Waveform (ANOW) detects small endolymphatic manipulations that may go undetected by conventional measurements [PDF]

, 2017
Electrocochleography (ECochG) has been used to assess Ménière's disease, a pathology associated with endolymphatic hydrops and low-frequency sensorineural hearing loss. However, the current ECochG techniques are limited for use at high-frequencies only (≥

Case Report: Unusual Neurological Features of Leigh Syndrome due to m.8993T>G Pathogenic Variant in the MT‐ATP6 Gene

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT The MT‐ATP6 gene m.8993T>G pathogenic variant has been associated with Leigh syndrome, especially in patients exhibiting a high degree of heteroplasmy. Although patients may present with a wide phenotypic spectrum, characteristic findings include bilateral, symmetric hyperintensities in the basal ganglia and brainstem on brain MRI ...

Cumulative emissions accounting of greenhouse gases due to path independence for a sufficiently rapid emissions cycle [PDF]

, 2020
Cumulative emissions accounting for carbon-dioxide (CO2) is founded on recognition that global warming in Earth System Models (ESMs) is roughly proportional to cumulative CO2 emissions, regardless of emissions pathway. However, cumulative emissions accounting only requires the graph between global warming and cumulative emissions to be approximately ...

Contralateral inhibition of click- and chirp-evoked human compound action potentials [PDF]

, 2017
Cochlear outer hair cells (OHC) receive direct efferent feedback from the caudal auditory brainstem via the medial olivocochlear (MOC) bundle. This circuit provides the neural substrate for the MOC reflex, which inhibits cochlear amplifier gain and is ...

Applications and Challenges of Auditory Brain‐Computer Interfaces in Objective Auditory Assessments for Pediatric Cochlear Implants

Exploration, EarlyView.
Auditory brain‐computer interface connects the brain with external devices and decodes neural signals related to auditory perception. Time‐domain and frequency‐domain analyses are commonly used to identify biomarkers associated with auditory rehabilitation, such as cortical auditory evoked potentials and mismatch negativity.
