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.

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.

Cupulolithiasis: A Critical Reappraisal

OTO Open, Volume 7, Issue 1, January–March 2023., 2023
Abstract Objective To review the history and pathophysiologic theories for cupulolithiasis and canalith jam in benign paroxysmal positional vertigo. Data Sources PubMed, Google Scholar. Review Methods Three PubMed and Google Scholar searches were performed, keywords: “cupulolithiasis,” “apogeotropic [and] benign,” and “canalith jam,” resulting in 187 ...

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‐

Immediate repeated testing (IRT) for BPPV: A cost‐effective examination

Laryngoscope Investigative Otolaryngology, Volume 7, Issue 3, Page 832-834, June 2022., 2022
Abstract Objective To show that a negative Dix‐Hallpike test or Pagnini‐McClure test may convert into positive after head shaking in cases of semicircular canalith jam. Methods This is a retrospective study, where 768 cases of BPPV were studied of which 36 were found to have canalith jam.

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.

Benign paroxysmal positional vertigo and vestibular impairment among older adults with dizziness

Laryngoscope Investigative Otolaryngology, Volume 6, Issue 3, Page 488-495, June 2021., 2021
Abstract Objective This article aimed to investigate older adults visiting a geriatric institution for a bone density measurement who reported dizziness on a daily or weekly basis (but who are not seeking care for dizziness), according to BPPV, vestibular function, walking abilities, and frequency of falls.

Frequency of vateritic otoliths and potential consequences for marine survival in hatchery‐reared Atlantic salmon

Journal of Fish Biology, Volume 98, Issue 5, Page 1401-1409, May 2021., 2021
Abstract Otoliths are inner‐ear structures of all teleost fish with functional importance for hearing and balance. The otoliths usually consist of aragonite, a polymorph of calcium carbonate, but may also take the form partly or entirely of vaterite, a different polymorph of calcium carbonate.
