Unravelling the phylogeny of armadillos and their kin (Mammalia, Xenarthra, Cingulata) combining morphological, molecular, and stratigraphic data

Cladistics, EarlyView.
Abstract Cingulata, a major lineage of Xenarthra, comprises extinct and extant armoured placental mammals that diversified throughout the Cenozoic. Despite extensive study, phylogenetic hypotheses based on morphological and molecular data remain incongruent, and no total evidence analysis has been conducted. Here, we integrate the largest morphological

Responses of pigeon horizontal semicircular canal afferent fibers. I. Step, trapezoid, and low-frequency sinusoid mechanical and rotational stimulation

, 1989
1. The horizontal semicircular canals of anesthetized (barbiturate/ketamine) pigeons were stimulated by rotational and by mechanical stimulation. 2. The mechanical stimulation consisted of making a small (less than 1 mm) fistula in the lateral part of ...

Benign paroxysmal positional vertigo

Journal of Indira Gandhi Institute of Medical Sciences
Benign paroxysmal positional vertigo (BPPV) is the leading etiology of peripheral vertigo. It manifests with transient, recurring bouts of vertigo brought on by movements of the head.

Epley’s Influence on Horizontal Canal BPPV Variants

Audiology Research
Dr. Epley has been instrumental in defining the mechanisms and treatment of BPPV variants, including those of the horizontal canals. Cupulolithiasis is a horizontal canal BPPV variant usually defined as direction-changing apogeotropic nystagmus.

Nocturnal Hypoxemia Burden Correlates With Vestibular Dysfunction in Obstructive Sleep Apnea

Clinical Otolaryngology, EarlyView.
ABSTRACT Introduction Obstructive sleep apnea (OSA) is a potential contributor to vestibular dysfunction, though specific correlating parameters remain unclear. This study aimed to determine whether hypoxemia severity indices correlate quantitatively with caloric slow‐phase eye velocity (SPV), a marker of vestibular function. Methods In a retrospective

Comparative morphology of the vestibular semicircular canals in therian mammals [PDF]

, 2013
textThe peripheral vestibular membranous ducts that detect angular motion are contained within bony semicircular canals of mammalian petrosals. I investigated morphology and function in the three membranous semicircular ducts through measurements on the

Costimulation of the Horizontal Semicircular Canal during Skull Vibrations in Superior Canal Dehiscence Syndrome

, 2014
A sound- and pressure-induced vestibuloocular reflex (VOR) has been described as vertical and torsional in superior canal dehiscence (SCD), and the rotational axes of induced VOR have been assumed to fit with the axis of the affected superior ...

Vestibular Function Pre‐ and Post‐cochlear Implantation in Adult Patients With Inner Ear Malformations: A Retrospective Cohort Study

Sensory Neuroscience
This study aimed to investigate the vestibular function (VF) across different types of inner ear malformations (IEMs) in adult patients, and to evaluate the long‐term effects of cochlear implantation (CI) on VF.
