Carotid Sympathetic Plexus Schwannoma Presenting as Middle Ear and External Auditory Canal Mass

Ear, Nose & Throat Journal, 2023
Schwannomas in the middle ear and external auditory canal are exceedingly rare. The facial nerve, chorda tympani nerve, and Jacobson’s nerve have rarely been reported as the origins of primary schwannomas in the middle ear cavity.

Differential roles for EphA and EphB signaling in segregation and patterning of central vestibulocochlear nerve projections. [PDF]

PLoS ONE, 2013
Auditory and vestibular afferents enter the brainstem through the VIIIth cranial nerve and find targets in distinct brain regions. We previously reported that the axon guidance molecules EphA4 and EphB2 have largely complementary expression patterns in ...

Macrophage-Mediated Glial Cell Elimination in the Postnatal Mouse Cochlea

Frontiers in Molecular Neuroscience, 2017
Hearing relies on the transmission of auditory information from sensory hair cells (HCs) to the brain through the auditory nerve. This relay of information requires HCs to be innervated by spiral ganglion neurons (SGNs) in an exclusive manner and SGNs to

Metabolic decline in an insect ear: correlative or causative for age-related auditory decline?

Frontiers in Cell and Developmental Biology, 2023
One leading hypothesis for why we lose our hearing as we age is a decrease in ear metabolism. However, direct measurements of metabolism across a lifespan in any auditory system are lacking.

The diameters of guinea pig auditory nerve fibres: Distribution and correlation with spontaneous rate [PDF]

, 1993
In the mammalian auditory nerve physiological recordings revealed that the spontaneous discharge rate of single auditory fibres correlates with the diversity of input-output functions which may be important for intensity discrimination (e.g., Sachs and ...

Facial nerve stimulation necessitating auditory brainstem implantation: 8 years follow-up a case report

Acta Oto-Laryngologica Case Reports, 2021
Inner ear malformations are one of the common causes of hearing loss. Common cavity is extremely rare among the types of inner ear anomalies. In this study, 8-years development period of a boy with common cavity is presented.

Temporal modulation transfer functions in the European Starling (Sturnus vulgaris): II. Responses of auditory-nerve fibres [PDF]

, 1995
The temporal resolution of cochlear-nerve fibres in the European starling was determined with sinusoidally amplitude-modulated noise stimuli similar to those previously used in a psychoacoustic study in this species (Klump and Okanoya, 1991).

Optogenetic Stimulation of the Auditory Nerve [PDF]

Journal of Visualized Experiments, 2014
Direct electrical stimulation of spiral ganglion neurons (SGNs) by cochlear implants (CIs) enables open speech comprehension in the majority of implanted deaf subjects(1-) (6). Nonetheless, sound coding with current CIs has poor frequency and intensity resolution due to broad current spread from each electrode contact activating a large number of SGNs ...

Does size of the cochlear nerve affect postoperative auditory performance in pediatric cochlear implant patients with normal cochlear nerves?

Brazilian Journal of Otorhinolaryngology, 2022
Introduction: Cochlear implantation is an effective treatment method for severe to profound hearing loss. Many factors that may influence cochlear implantation success have been explained in previous studies.

The Corticofugal Effects of Auditory Cortex Microstimulation on Auditory Nerve and Superior Olivary Complex Responses Are Mediated via Alpha-9 Nicotinic Receptor Subunit.

PLoS ONE, 2016
Background and objectiveThe auditory efferent system is a complex network of descending pathways, which mainly originate in the primary auditory cortex and are directed to several auditory subcortical nuclei.
