Asymmetrically severe internal auditory canal hypoplasia: A case report. [PDF]
, 2020 We present a case of an otherwise healthy 20-month-old with congenital sensorineural hearing loss. CT and MR imaging demonstrated bilateral asymmetrically severe hypoplasia of the internal auditory canals and vestibulocochlear nerves.

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 ...

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 ...

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 ...

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 ...

Head Direction Cell Activity Is Absent in Mice without the Horizontal Semicircular Canals
Journal of Neuroscience, 2016 Head direction (HD) cells fire when an animal faces a particular direction in its environment, and they are thought to represent the neural correlate of the animal's perceived spatial orientation.

Functional implications of ubiquitous semicircular canal non-orthogonality in mammals.
PLoS ONE, 2013 The 'canonical model' of semicircular canal orientation in mammals assumes that 1) the three ipsilateral canals of an inner ear exist in orthogonal planes (i.e., orthogonality), 2) corresponding left and right canal pairs have equivalent angles (i.e ...
