The induction and compensation of asymmetric eye movements following unilateral blockage of a horizontal semicircular canal in the rabbit

, 1988
The influence of unilateral plugs of the left horizontal semicircular canal (LHC plugs) of rabbits on the development and compensation of asymmetric eye movements evoked by horizontal vestibular stimulation was studied.

Prognosis and Horizontal Semicircular Canal Function in HC-BPPV

Equilibrium Research, 2005
We report horizontal canal BPPV (HC-BPPV) on targeting its pathophysiology, horizontal semicircular canal function and prognosis together with a review of the literature. Nineteen patients were classified into 9 with canalolithiasis and 10 cupulolithiasis.

Posterior Semicircular Canal Dehiscence with Vestibulo-Ocular Reflex Reduction for the Affected Canal at the Video-Head Impulse Test: Considerations to Pathomechanisms

Audiology Research
Posterior semicircular canal dehiscence (PSCD) has been demonstrated to result in a third mobile window mechanism (TMWM) in the inner ear similar to superior semicircular canal dehiscence (SSCD).

Effect of Unilateral Elimination of the Horizontal Semicircular Canal in the Pike [PDF]

Nature, 1937
IN a recent publication1 it was shown that in the dogfish the sense organ situated in the ampulla of the horizontal semicircular canal is in a constant state of excitation. This activity is maintained in the resting animal in the absence of any obvious external stimulus.

Influence of semicircular canal morphology on the VOR and swimming activity in larval amphibians: a comparative study in Xenopus and axolotl

Frontiers in Neurology
Gaze stabilization and locomotion rely often on an accurate sensory detection of head movements by the vestibular system. A functional relationship between vestibular sensitivity, locomotor skills and semicircular canal morphology has been suspected in ...

A Biomechanical Model of the Inner Ear: Numerical Simulation of the Caloric Test

The Scientific World Journal, 2013
Whether two vertical semicircular canals can receive thermal stimuli remains controversial. This study examined the caloric response in the three semicircular canals to the clinical hot caloric test using the finite element method.

Comparative morphology of the vestibular semicircular canals in therian mammals

, 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

Sensory transduction of head velocity and acceleration in the toadfish horizontal semicircular canal

, 1994
1. Sinusoidal mechanical indentation of the long-and-slender limb of the horizontal semicircular canal and/or utricle was used to produce adequate stimulation of the labyrinth.
