Central projections of auditory nerve fibers in the western rat snake (Pantherophis obsoletus)

Journal of Comparative Neurology, Volume 531, Issue 12, Page 1261-1273, August 2023., 2023
The western rat snake does not have a tympanum but is able to detect low‐frequency vibrations. Using tract tracing, we found that auditory nerve fibers of the western rat snake project to two distinct cochlear nuclei, consistent with other reptiles. Auditory pathways are present despite loss of sensitivity to airborne sound.

Inner ear morphology in the Atlantic molly Poecilia mexicana--first detailed microanatomical study of the inner ear of a cyprinodontiform species. [PDF]

PLoS ONE, 2011
BACKGROUND: Fishes show an amazing diversity in hearing abilities, inner ear structures, and otolith morphology. Inner ear morphology, however, has not yet been investigated in detail in any member of the diverse order Cyprinodontiformes.

Assessment of semicircular canal function in benign paroxysmal positional vertigo using the video head impulse test and caloric test

Laryngoscope Investigative Otolaryngology, Volume 8, Issue 2, Page 525-531, April 2023., 2023
The VOR gain of vHIT in the affected canal was significantly smaller than that in the contralateral canal in p‐BPPV, but not in h‐BPPV. The caloric responses of the affected canal are reduced to a significantly larger extent in h‐BPPV compared to p‐BPPV.

The heterogeneity of mammalian utricular cells over the course of development

Clinical and Translational Medicine, Volume 12, Issue 10, October 2022., 2022
Single‐cell RNA‐seq identified several cell clusters in whole mouse utricle sensory epithelia from the neonatal period to adulthood. New HCs mainly differentiated from Sox9 progenitor cells, and only a few were produced by mitotic proliferation. Ubch10 cells could generate HCs mitotically in adulthood.

Vestibular Extremely Low‐Frequency Magnetic and Electric Stimulation Effects on Human Subjective Visual Vertical Perception

Bioelectromagnetics, Volume 43, Issue 6, Page 355-367, September 2022., 2022
Electric fields from both extremely low‐frequency magnetic fields (ELF‐MF) and alternating current (AC) stimulations impact human neurophysiology. As the retinal photoreceptors, vestibular hair cells are graded potential cells and are sensitive to electric fields. Electrophosphene and magnetophosphene literature suggests different impacts of AC and ELF‐

Effect of Vitamin D Deficiency on the Occurrence and Recurrence of Benign Paroxysmal Positional Vertigo: A Narrative Review [PDF]

Kirkuk Journal of Medical Sciences
Benign paroxysmal positional vertigo (BPPV) is a short-lived attack of rotatory vertigo provoked by certain head movements. The most acceptable theories for its pathogenesis are canalithiasis and cupulolithiasis as a result of the detachment of otoconia ...

Comparative Histopathologic Analysis of Inner Ear Damage in Meningitis: Otogenic Versus Meningogenic Routes. [PDF]

Laryngoscope
A comparative study distinguishing histopathologic patterns of inner ear changes between meningogenic and otogenic routes in meningitis cases. Otogenic cases displayed a higher prevalence of changes in the spiral ligament and signs of early ossification, whereas meningogenic cases associated with a higher degree of vestibular damage.

Role of Vestibular Evoked Myogenic Potentials as an Indicator of Recovery in Patients with Benign Paroxysmal Positional Vertigo

Acta Clinica Croatica, 2017
Ocular vestibular evoked myogenic potentials (oVEMP) and cervical VEMP (cVEMP) are newer diagnostic methods, which allow an insight into the otolith senses.

Residual dizziness after successful repositioning maneuver for idiopathic benign paroxysmal positional vertigo: a review

Audiology Research, 2017
The benign paroxysmal positional vertigo (BPPV) is a vestibular disorder cause of vertigo. The BPPV may be corrected mechanically by repositioning maneuvers but even after successful maneuvers, some patients report residual dizziness for a certain period
