Subjective visual vertical with the bucket method in Brazilian healthy individuals

Brazilian Journal of Otorhinolaryngology
INTRODUCTION: The capacity of a healthy individual to estimate the true vertical in relation to the Earth when a fluorescent line is aligned in a completely dark room is called the subjective visual vertical.

An Electron Microscopic Study of the Otolithic Membrane

Practica Oto-Rhino-Laryngologica, 1978
Morphological studies were made of the otolithic membrane in its normal and pathological states in guinea pig, mice and squirrel monkey using scanning and transmission electron microscopes.The otolithic membrane normally consists of three layers; the first layer, situated nearest the endolymph, is an otoconial layer wherein otoconia of calcite form of ...

Molecular Biomarkers in Meniere's Disease: A Scoping Review of Current Evidence

Otolaryngology–Head and Neck Surgery, EarlyView.
Abstract Objective Meniere's disease is a complex chronic inner ear condition that is characterized by vertigo, tinnitus, aural fullness, and progressive hearing loss. Currently, diagnostic strategies remain symptom‐driven, and treatments focus on management of discrete episodes rather than targeting underlying pathophysiology.

Comparative Cochlear–Vestibular Aging Reveals Age‐Aligned Mitochondrial Ultrastructural Burden, Mitophagy–Autophagy Remodeling, Synaptic Uncoupling, and Sensory Functional Decline

Aging Cell, Volume 25, Issue 7, July 2026.
This study maps age‐aligned cochlear and vestibular decline in SAMP8 mice, linking functional impairment with synaptic vulnerability, mitochondrial ultrastructural injury, and autophagy/mitophagy–lysosome transcriptional remodeling. The findings provide an integrated framework for understanding shared inner‐ear aging trajectories.

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 ...

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

Journal of Comparative Neurology, Volume 534, Issue 4, April 2026.
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 ...

Electrical Control of the Transduction Channels’ Gating Force in Mechanosensory Hair Cells

Advanced Science, Volume 13, Issue 16, 18 March 2026.
The inner ear's hair cells rely on mechanosensitive ion channels to convert vibrations of their hair‐bundle into electrical signals. We show that varying the electrical potential (U) across the sensory epithelium modulates a key determinant of mechanosensitivity—the gating force (FG)—by modulating the gating swing (d), ranging from the size of the ...

Role of Hearing Loss Genes in the Sensory Epithelia Associated With Meniere Disease

Sensory Neuroscience, Volume 2, Issue 1, March 2026.
ABSTRACT Meniere disease (MD) is an inner ear disorder characterized by episodic vertigo, tinnitus, fluctuating sensorineural hearing loss (SNHL), and aural fullness. Its hallmark pathological feature is endolymphatic hydrops. MD shows significant familial clustering in European and East Asian populations, supporting a strong genetic component in ...

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

The Laryngoscope, Volume 135, Issue 10, Page 3859-3866, October 2025.
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.
