Vestibulo-Ocular Reflex Abnormalities in Posterior Semicircular Canal Benign Paroxysmal Positional Vertigo: A Pilot Study [PDF]

Iranian Journal of Otorhinolaryngology, 2017
Introduction: Benign paroxysmal positional vertigo (BPPV), involving the semicircular canals, is one of the most common diseases of the inner ear. The video head impulse test (vHIT) is a new test that examines the function of the canals. This study aimed

Spontaneous Jamming of Horizontal Semicircular Canal Combined with Canalolithiasis of Contralateral Posterior Semicircular Canal [PDF]

Journal of Audiology and Otology, 2022
Spontaneous canalith jam is an uncommon form of benign paroxysmal positional vertigo mimicking acute vestibular neuritis. We described for the first time a spontaneous horizontal semicircular canalith jam associated with a typical canalolithiasis involving contralateral posterior semicircular canal (PSC), illustrating how the latter condition modified ...

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

, 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 ...

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 ...

Superior canal dehiscence syndrome – case report [PDF]

Romanian Journal of Neurology, 2012
We report a case of a patient with superior semicircular canal dehiscence syndrome, a recently described condition in which vestibular imbalance and/or hearing loss results from the discontinuity of the bone overlying the superior semicircular canals ...
