La dehiscencia del canal semicircular superior como forma de presentación de la vestibulopatía periférica

Medicentro, 2017
Introducción: la dehiscencia del canal semicircular superior es una alteración del oído interno caracterizada por la ausencia parcial de la cobertura ósea de dicho canal. En condiciones normales, el oído interno solamente tiene dos ventanas: la oval y la

Three-dimensional characteristics of nystagmus induced by low frequency in semicircular canals of healthy young people

Frontiers in Neuroscience
ObjectiveThe study aimed to analyze the three-dimensional characteristics of nystagmus induced by different semicircular canal combinations in healthy young people, and to determine the reference range of nystagmus slow phase velocity (SPV) and its ...

Long‐term stability of transcrestal sinus augmentation

Periodontology 2000, EarlyView.
Abstract Transcrestal sinus augmentation has emerged as a minimally invasive alternative to lateral window techniques for vertical bone augmentation in the edentulous maxilla. Since its early introduction and modification over the last several decades, this technique has demonstrated predictable outcomes for implant placement in regions with limited ...

An experimentally informed computational model of neurovestibular adaptation to altered gravity

Experimental Physiology, EarlyView.
Abstract Transitions to altered gravity environments result in acute sensorimotor impairment for astronauts, leading to serious mission and safety risks in the crucial first moments in a new setting. Our understanding of the time course and severity of impairment in the early stages of adaptation remains limited and confounded by unmonitored head ...

Galvanic vestibular stimulation reveals disruption of ipsilesional brainstem pathways in hemiparetic stroke survivors

Experimental Physiology, EarlyView.
Abstract The spatiotemporal structure of muscle coordination emerges from the collaboration and competition among cortical, brainstem and spinal pathways onto motor neuron pools, each continuously shaped by task demands, limb position and descending tract integrity.

Development of and adherence to artificial gravity and resistive vibration exercises during 60 days of hypoxic 6° head‐down tilt bed rest: BRAVE study

Experimental Physiology, EarlyView.
Abstract Artificial gravity (AG) combined with resistive vibration exercise has been proposed as a multi‐system countermeasure for long‐duration spaceflight; however, its operational feasibility during prolonged unloading remains insufficiently characterised.

A contribution to the anatomy of two rare cetacean species: The hourglass dolphin (Cephalorhynchus cruciger) and the spectacled porpoise (Phocoena dioptrica)

The Anatomical Record, Volume 309, Issue 7, Page 1797-1820, July 2026.
Abstract The anatomical description of the hourglass dolphin (Cephalorhynchus cruciger) and the spectacled porpoise (Phocoena dioptrica) remains largely unexplored, due to limited specimen availability and preservation challenges. This study employed digital imaging techniques, conventional histology, and computed tomography to provide visualization of
