Image motion with color contrast suffices to elicit an optokinetic reflex in Xenopus laevis tadpoles
Scientific Reports, 2021 The optokinetic reflex is a closed-loop gaze-stabilizing ocular motor reaction that minimizes residual retinal image slip during vestibulo-ocular reflexes.

Ontogeny of murine bony semicircular canal form
The Anatomical Record, EarlyView.Abstract The labyrinthine geometry and functional anatomy of the semicircular canals have intrigued scientists for decades, and there has been considerable interest in understanding how these complex structures grow and develop with evidence emerging from human studies that size maturation occurs exceptionally early by comparison with other systems ...

Functional Dissociation Between Cervical VEMP and Posterior Canal vHIT in 1770 Unselected Ears
The Laryngoscope, EarlyView.Cervical VEMP and posterior canal vHIT are conventionally treated as measures of a single inferior vestibular unit. In 1770 unselected ears from a diagnosis‐agnostic registry, the two tests disagreed in 72.7% of ears abnormal on at least one test, with chance‐corrected agreement near zero (κ = 0.097) and unchanged across age strata.

Factors Associated With Bilateral Involvement in Non‐Infectious Labyrinthitis: A Case–Control Study
The Laryngoscope, EarlyView.Non‐infectious labyrinthitis may progress from unilateral to bilateral inner‐ear involvement, resulting in greater functional impairment. In this retrospective case–control study of 50 patients, younger age, female sex, and the presence of systemic disease were associated with bilateral involvement. These exploratory findings may help identify patients

Frontiers in Computational Neuroscience, 2015 The vestibulo-ocular reflex (VOR) is an involuntary eye movement evoked by head movements. It is also influenced by viewing distance. This paper presents a hybrid nonlinear bilateral model for the horizontal angular vestibulo-ocular reflex (AVOR) in the ...

Video ocular counter roll: A bedside test of otolith‐ocular function
Annals of Clinical and Translational Neurology, 2023 Here we review the clinical value of a video‐oculography test for clinical evaluation of vestibular otolith function. This test is known as the video ocular counter roll (vOCR) and is based on measurement of torsional vestibulo‐ocular reflex with a ...
