Morphometric study of the bony labyrinth of the inner ear in the European moles Talpa europaea, Talpa occidentalis, and Talpa aquitania. [PDF]

open access: yesJ Anat
The study investigates the shape of the semicircular canals in the inner ear of three sister mole species—Talpa europaea, Talpa aquitania, and Talpa occidentalis—using geometric morphometrics on 58 specimens. It finds both interspecific and intraspecific variability in canal morphology, but no evidence of sexual dimorphism.

Protective Effect of Metformin on Gentamicin-Induced Vestibulotoxicity in Rat Primary Cell Culture [PDF]

open access: yesClinical and Experimental Otorhinolaryngology, 2014
ObjectivesOne of the antidiabetic drugs, metformin, have shown that it prevented oxidative stress-induced death in several cell types through a mechanism involving the opening of the permeability transition pore and cytochrome c release.

Brainstem hyperintensity in patients with vestibular schwannoma is associated with labyrinth signal on magnetic resonance imaging but not vestibulocochlear tests

open access: yesThe Neuroradiology Journal, 2020
Objectives Focal hyperintensity in the dorsal brainstem (HDB) has been described in large cerebellopontine angle tumours and is thought to represent vestibular nuclei degeneration, but its functional significance has not been thoroughly investigated. Our

Unilateral enlarged vestibular aqueduct syndrome and bilateral endolymphatic hydrops [PDF]

open access: yes, 2017
Enlarged vestibular aqueduct (EVA) syndrome is a common congenital inner ear malformation characterized by a vestibular aqueduct with a diameter larger than 1.5 mm, mixed or sensorineural hearing loss that ranges from mild to profound, and vestibular ...

A mathematical model for top-shelf vertigo: the role of sedimenting otoconia in BPPV [PDF]

open access: yes, 2003
Benign Paroxysmal Positional Vertigo (BPPV) is a mechanical disorder of the vestibular system in which calcite particles called otoconia interfere with the mechanical functioning of the fluid-filled semicircular canals normally used to sense rotation ...

Protons as Messengers of Intercellular Communication in the Nervous System

open access: yesFrontiers in Cellular Neuroscience, 2018
In this review, evidence demonstrating that protons (H+) constitute a complex, regulated intercellular signaling mechanisms are presented. Given that pH is a strictly regulated variable in multicellular organisms, localized extracellular pH changes may ...
