Physical and geometric constraints explain the labyrinth-like shape of the nasal cavity

open access: yes, 2017
The nasal cavity is a vital component of the respiratory system that heats and humidifies inhaled air in all vertebrates. Despite this common function, the shapes of nasal cavities vary widely across animals.

Electrogenic transport and K(+) ion channel expression by the human endolymphatic sac epithelium. [PDF]

open access: yes, 2015
The endolymphatic sac (ES) is a cystic organ that is a part of the inner ear and is connected to the cochlea and vestibule. The ES is thought to be involved in inner ear ion homeostasis and fluid volume regulation for the maintenance of hearing and ...

Predicting ecology and hearing sensitivities in Parapontoporia—An extinct long‐snouted dolphin

open access: yesThe Anatomical Record, EarlyView.
Abstract Analyses of the cetacean (whale and dolphin) inner ear provide glimpses into the ecology and evolution of extinct and extant groups. The paleoecology of the long‐snouted odontocete (toothed whale) group, Parapontoporia, is primarily marine with its depositional context also suggesting freshwater tolerance.

Vestibular evoked myogenic potential: we propose a new instrument

open access: yesInternational Archives of Otorhinolaryngology, 2010
Introduction: Currently, there is still no specific instrument for assessment of vestibular evoked myogenic potentials, with the same performed by a device designed to capture auditory evoked potentials available in the market.

Ipsilateral cochlear implantation in cases with vestibular schwannoma

open access: yesEye &ENT Research, EarlyView.
Abstract Background Vestibular schwannomas (VS) are the most common tumors in the cerebellopontine angle, which can lead to hearing loss, particularly following tumor resection. For patients with bilateral VS associated with neurofibromatosis type 2 (NF2), hearing loss significantly undermines their quality of life.

Rapid adaptation of multisensory integration in vestibular pathways

open access: yesFrontiers in Systems Neuroscience, 2015
Sensing gravity is vital for our perception of spatial orientation, the control of upright posture, and generation of our every day activities. When an astronaut transitions to microgravity or returns to earth, the vestibular input arising from self ...

Otopathologic Patterns of Cellular Degeneration in the Peripheral Vestibular Organ Secondary to Head Trauma

open access: yesThe Laryngoscope, EarlyView.
This study examines vestibular degeneration following head trauma, comparing cases with and without fractures. Histopathological analysis of 26 temporal bones showed more severe damage in nonfracture cases, particularly in Scarpa's ganglion cells and vestibular hair cells.

Role of Alpha-band Oscillations in Spatial Updating across Whole Body Motion

open access: yesFrontiers in Psychology, 2016
When moving around in the world, we have to keep track of important locations in our surroundings. In this process, called spatial updating, we must estimate our body motion and correct representations of memorized spatial locations in accordance with ...

Peripheral vestibular syndrome in cats: Clinical presentation, diagnostic findings and outcome in 196 cases

open access: yesVeterinary Record, EarlyView.
Abstract Background Disorders of the vestibular system are frequent in cats. This study aimed to describe the clinical presentation, diagnostic findings, underlying aetiologies and outcome of cats with peripheral vestibular syndrome (PVS). Methods This was a retrospective study of cats presented with PVS at four referral hospitals.
