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

, 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 ...

Development of a dynamic virtual reality model of the inner ear sensory system as a learning and demonstrating tool [PDF]

, 2009
In order to keep track of the position and motion of our body in space, nature has given us a fascinating and very ingenious organ, the inner ear. Each inner ear includes five biological sensors - three angular and two linear accelerometers - which ...

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 ...

The Tangential Nucleus Controls a Gravito-inertial Vestibulo-ocular Reflex [PDF]

, 2014
Whilst adult vertebrates sense changes in head position using two classes of accelerometer, at larval stages zebrafish lack functional semicircular canals and rely exclusively on their otolithic organs to transduce vestibular information.

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

Retinitis pigmentosa: evaluation of the vestibular system with cervical and ocular vestibular evoked myogenic potentials and the video head impulse test [PDF]

, 2015
OBJECTIVE: Retinitis pigmentosa (RP) represents a group of inherited disorders in which abnormalities of the photoreceptors lead to progressive visual loss.

Subjective visual vertical with the bucket method in Brazilian healthy individuals

Brazilian Journal of Otorhinolaryngology
INTRODUCTION: The capacity of a healthy individual to estimate the true vertical in relation to the Earth when a fluorescent line is aligned in a completely dark room is called the subjective visual vertical.

Early synapsids neurosensory diversity revealed by CT and synchrotron scanning

The Anatomical Record, EarlyView.
Abstract Non‐mammaliaform synapsids (NMS) represent the closest relatives of today's mammals among the early amniotes. Exploring their brain and nervous system is key to understanding how mammals evolved. Here, using CT and Synchrotron scanning, we document for the first time three extreme cases of neurosensory and behavioral adaptations that probe ...

Otopathologic Patterns of Cellular Degeneration in the Peripheral Vestibular Organ Secondary to Head Trauma

The Laryngoscope, Volume 135, Issue 10, Page 3859-3866, October 2025.
This study examines vestibular degeneration following head trauma, comparing cases with and without fractures. Histopathological analysis of 26 temporal bones showed more severe damage in nonfracture cases, particularly in Scarpa's ganglion cells and vestibular hair cells.
