The use of videonystagmography head impulse test (VHIT) in the diagnostics of semicircular canal injuries in patients with vertigo

open access: yesInternational Journal of Occupational Medicine and Environmental Health, 2014
Objectives: The aim of the study was to assess the function of semicircular canal in videonystagmography head impulse test (VHIT) in the patients with vertigo and balance disorders.

Semicircular canal system in early primates

open access: yesJournal of Human Evolution, 2009
Mammals with more rapid and agile locomotion have larger semicircular canals relative to body mass than species that move more slowly. Measurements of semicircular canals in extant mammals with known locomotor behaviours can provide a basis for testing hypotheses about locomotion in fossil primates that is independent of postcranial remains, and a ...

Ectopic Noggin Blocks Sensory and Nonsensory Organ Morphogenesis in the Chicken Inner Ear [PDF]

open access: yes, 1999
Bone morphogenetic protein 4 (Bmp4) is expressed during multiple stages of development of the chicken inner ear. At the otocyst stage, Bmp4 is expressed in each presumptive sensory organ, as well as in the mesenchymal cells surrounding the region of the ...

Repeated video head impulse testing in patients is a stable measure of the passive vestibulo-ocular reflex

open access: yesJournal of Otology, 2021
Objectives: The video head impulse test (vHIT) is used as a measure of compensation yet it’s stability in patients with vestibular pathology is unknown. Methods: 144 patients (n = 72 female, mean 54.46 ± 15.8 years) were grouped into one of three primary

Perception of the Body in Space: Mechanisms [PDF]

open access: yes
The principal topic is the perception of body orientation and motion in space and the extent to which these perceptual abstraction can be related directly to the knowledge of sensory mechanisms, particularly for the vestibular apparatus.

Size, not phylogeny, explains the morphology of the endosseous labyrinth in the crown clade Crocodylia

open access: yesJournal of Anatomy, Volume 246, Issue 4, Page 558-574, April 2025.
Here, we present the most complete dataset to date on the endosseous labyrinths of extant crocodylians. Using 3D geometric morphometrics, we show that allometry constitutes a major contributor of the shape variation of the crocodylian endosseous labyrinths and that the development of this structure is likely linked to the braincase conformation, in all

Osteohistology of the unusually fast‐growing theropod dinosaur Ceratosaurus

open access: yesJournal of Anatomy, EarlyView.
We report the histology of multiple elements attributed to four individuals of Ceratosaurus. We find that the histology and growth models corroborate previous reports of rapid tissue growth in the genus. Abstract Ceratosaurus is a large‐bodied non‐avian theropod dinosaur known from the Upper Jurassic Morrison Formation of North America and is ...
