Ototoxicidade por organofosforados: descrição dos aspectos ultraestruturais do sistema vestibulococlear de cobaias Organophosphate-related ototoxicity: Description of the vestibulocochlear system ultrastructural aspects of guinea pigs

Brazilian Journal of Otorhinolaryngology, 2010
Os agrotóxicos organofosforados são amplamente utilizados na agricultura, e atualmente fazem parte do grupo de agentes químicos que podem levar à perda auditiva, no qual já estavam incluídos os solventes, os metais e os asfixiantes.

Morphology and morphometry of the inner ear of the dromedary camel and their influence on the efficiency of hearing and equilibrium

Zoological Letters, 2022
Background The inner ear morphology and size are linked to hearing and balance ability. The goal of this study was to determine the morphology and morphometrics of the dromedary camel's inner ear and how it influences hearing accommodation and ...

Early synapsids neurosensory diversity revealed by CT and synchrotron scanning

The Anatomical Record, Volume 309, Issue 4, Page 912-929, April 2026.
Abstract Non‐mammaliaform synapsids (NMS) represent the closest relatives of today's mammals among the early amniotes. Exploring their brain and nervous system is key to understanding how mammals evolved. Here, using CT and Synchrotron scanning, we document for the first time three extreme cases of neurosensory and behavioral adaptations that probe ...

Calcium functional imaging with high-resolution CT in the inner ear

Scientific Reports, 2021
Although the otolith and otolith organs correlate with vertigo and instability, there is no method to investigate them without harmful procedures. We will create the technique for 3D microanatomical images of them, and investigate the in vivo internal ...

Subjective Visual Vertical and Vestibular Evoked Myogenic Potential in Meniere's disease

Brazilian Journal of Otorhinolaryngology, 2023
Objective: To evaluate otolith function by comparing the findings of the Subjective Visual Vertical, the cervical Vestibular Evoked Myogenic Potential and the ocular Vestibular Evoked Myogenic Potential tests in patients in the inter-crisis period of ...

Brain Morphology and Quantitative Assessment of Sensory Brain Areas in Southern Bluefin Tuna, Thunnus maccoyii (Scombridae, Teleostei) [PDF]

J Comp Neurol
The absolute and relative volume of major sensory and integrative brain regions of the southern bluefin tuna Thunnus maccoyii are examined using magnetic resonance imaging (MRI). A dominant cerebellum projects into the midbrain ventricular space, while the optic tectum represents a smaller proportion of total brain volume than previously estimated ...

Midline Head Tap to Image the Human Vestibular Cortex on fMRI

Journal of the Royal Society of New Zealand, Volume 56, Issue 2, April 2026.
A simple head tap can stimulate inner ear otolith organ activation. In this pilot proof‐of‐concept study, midline forehead taps were delivered in the magnetic resonance imaging (MRI) scanner to elicit an observable response in the areas most suspected of representing a vestibular cortex.

The dorsolateral prefrontal cortex as a potential target for electrical stimulation in the treatment of vestibular‐based nausea

The Journal of Physiology, Volume 604, Issue 5, Page 1773-1787, 1 March 2026.
Abstract figure legend Recent work has shown transcranial electrical stimulation of the dorsolateral prefrontal cortex (dlPFC) to mitigate vestibular perceptions. Though definitive pathways require further elucidation, this interaction may be modulated by dlPFC inhibitory action on vestibular signalling in the insular cortex, thalamus and/or the ...

Morphometric study of the bony labyrinth of the inner ear in the European moles Talpa europaea, Talpa occidentalis, and Talpa aquitania

Journal of Anatomy, Volume 248, Issue 1, Page 71-81, January 2026.
The study investigates the shape of the semicircular canals in the inner ear of three sister mole species—Talpa europaea, Talpa aquitania, and Talpa occidentalis—using geometric morphometrics on 58 specimens. It finds both interspecific and intraspecific variability in canal morphology, but no evidence of sexual dimorphism.
