Semicircular canal plane head impulses detect absent function of individual semicircular canals [PDF]

open access: yesBrain, 1998
We studied the human vestibulo-ocular reflex (VOR) in response to head 'impulses': brief, unpredictable, passive, high-acceleration (up to 4000 degrees/s2), low-amplitude (20-30 degrees) head rotations. We delivered the head impulses approximately in the plane of the semicircular canal (SCC) being tested.

Observational study on risk factors determining residual dizziness after successful benign paroxysmal positional vertigo treatment: The role of subclinical BPPV [PDF]

open access: yes, 2019
After successful treatment for benign paroxysmal positional vertigo, many patients may complain of residual dizziness. Possible explanations may be the persistence of otolith into canal insufficient to provoke noticeable nystagmus, utricular dysfunction ...

Design and analysis of HSC-BPPV diagnostic maneuver based on virtual simulation

open access: yesFrontiers in Neurology, 2023
BackgroundThe preferred supine roll test for the diagnosis of horizontal semicircular canal BPPV has several disadvantages, including difficulty in locating the affected ear, inconsistent nystagmus performance on repeated testing, and lack of a typical ...

Tullio phenomenon in superior semicircular canal dehiscence (SSCD) [PDF]

open access: yes, 2015
A 68-year-old woman presented with worsening sound-induced vertigo (Tullio phenomenon) and left-sided hearing loss. Weber's test lateralised to the affected ear and audiography confirmed mild conductive hearing loss.

Semicircular canal dehiscence

open access: yes, 2018
This chapter discusses Minor, Solomon, Zihreich, and Zee’s 1998 paper on semicircular canal dehiscence including the design of the study (outcome measures, results, conclusions, and a critique).

Technique of Multi-Planar CT Image Reconstruction for the Evaluation of Superior Semicircular Canal Dehiscence Syndrome

open access: yesPhilippine Journal of Otolaryngology Head and Neck Surgery, 2011
Superior semicircular canal dehiscence (SSCD) syndrome is an unusual cause of vertigo that was first identified by Minor in 1998. The patients initially described by Minor presented with vertigo, oscillopsia, and/or dysequilibrium related to sound ...

Semicircular canals in Anolis lizards: ecomorphological convergence and ecomorph affinities of fossil species [PDF]

open access: yesRoyal Society Open Science, 2017
Anolis lizards are a model system for the study of adaptive radiation and convergent evolution. Greater Antillean anoles have repeatedly evolved six similar forms or ecomorphs: crown-giant, grass-bush, twig, trunk, trunk-crown and trunk-ground.

Spatiotemporal symmetries in the disynaptic canal-neck projection [PDF]

open access: yes, 2007
The vestibular system in almost all vertebrates, and in particular in humans, controls balance by employing a set of six semicircular canals, three in each inner ear, to detect angular accelerations of the head in three mutually orthogonal coordinate ...

Semicircular Canal Influences on the Developmental Tuning of the Translational Vestibulo-Ocular Reflex

open access: yesFrontiers in Neurology, 2018
Vestibulo-ocular reflexes (VORs) rely on neuronal computations that transform vestibular sensory signals into spatio-temporally appropriate extraocular motor commands.
