A mathematical model for top-shelf vertigo: the role of sedimenting otoconia in BPPV [PDF]

open access: yes, 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 ...

Development of a dynamic virtual reality model of the inner ear sensory system as a learning and demonstrating tool [PDF]

open access: yes, 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: Lessons from the First 20 Years

open access: yesFrontiers in Neurology, 2017
Superior semicircular canal dehiscence syndrome was first reported by Lloyd Minor and colleagues in 1998. Patients with a dehiscence in the bone overlying the superior semicircular canal experience symptoms of pressure or sound-induced vertigo, bone ...

Turning semicircular canal function on its head: dinosaurs and a novel vestibular analysis. [PDF]

open access: yesPLoS ONE, 2013
Previous investigations have correlated vestibular function to locomotion in vertebrates by scaling semicircular duct radius of curvature to body mass. However, this method fails to discriminate bipedal from quadrupedal non-avian dinosaurs.

Superior Semicircular Canal Dehiscence in a Patient with Ehlers-Danlos Syndrome: A Case Report. [PDF]

open access: yes, 2017
Superior semicircular canal dehiscence (SSCD) is a bony defect in the middle cranial fossa floor that results in an abnormal connection between the inner ear and cranial vault.

Bilateral semicircular canal aplasia

open access: yesEuropean Annals of Otorhinolaryngology, Head and Neck Diseases, 2013
Bilateral semicircular canal aplasia is extremely rare; discovery, when the cochlear-vestibular system is normal and there is no hearing loss, is serendipitous.Bilateral semicircular canal aplasia was serendipitously discovered in a 24-year-old male during assessment of unilateral mixed hearing loss with subnormal contralateral hearing.

A 1-year follow-up study with C-VEMPs, O-VEMPs and video head impulse testing in vestibular neuritis [PDF]

open access: yes, 2014
The aim of this paper was to evaluate prospectively, in a group of patients affected by VN, a diagnostic protocol employing C-VEMPs, O-VEMPs and vHIT together.

The Mechanics of the Growing Semicircular Canal [PDF]

open access: yesJournal of Experimental Biology, 1973
ABSTRACT The motion of the endolymph in the semicircular canal is described with the aid of a linear second-order system, comprising the applied angular acceleration and the linear displacement, the linear velocity and the linear acceleration of the endolymph.

The endocranial morphology and inner ear of the abelisaurid theropod Aucasaurus garridoi [PDF]

open access: yes, 2015
A partial cranial endocast and right inner ear of the Cretaceous abelisaurid dinosaur Aucasaurus garridoi were digitally reconstructed from CT scans.
