Semicircular Canal Influences on the Developmental Tuning of the Translational Vestibulo-Ocular Reflex

Frontiers in Neurology, 2018
Vestibulo-ocular reflexes (VORs) rely on neuronal computations that transform vestibular sensory signals into spatio-temporally appropriate extraocular motor commands.

A Case of Right Apogeotropic Posterior Semicircular Canal BPPV that Initially Emulated as Left Anterior Semicircular Canal BPPV

Annals of Otology and Neurotology, 2020
In any patient with a history of rotational vertigo triggered by changes in the position of head relative to the gravity, whose oculomotor patterns elicit a positional downbeating nystagmus (p-DBN), the localization could be either central in the ...

An exploratory study to detect Ménière’s disease in conventional MRI scans using radiomics

Frontiers in Neurology, 2016
ObjectiveThe purpose of this exploratory study was to investigate whether a quantitative image analysis of the labyrinth in conventional MRI scans using a radiomics approach showed differences between patients with Ménière’s disease and the control group.

The video Head Impulse Test (vHIT) detects vertical semicircular canal dysfunction. [PDF]

PLoS ONE, 2013
BACKGROUND: The video head impulse test (vHIT) is a useful clinical tool to detect semicircular canal dysfunction. However vHIT has hitherto been limited to measurement of horizontal canals, while scleral search coils have been the only accepted method ...

The braincase of Malawisaurus dixeyi (Sauropoda: Titanosauria): A 3D reconstruction of the brain endocast and inner ear.

PLoS ONE, 2019
A braincase of the Cretaceous titanosaurian sauropod Malawisaurus dixeyi, complete except for the olfactory region, was CT scanned and a 3D rendering of the endocast and inner ear was generated. Cranial nerves appear in the same configuration as in other

Auditory Hair Cell Mechanotransduction Channels Dynamically Shape the Mechanical Properties of Their Membrane Environment

Advanced Science, EarlyView.
This work shows, for the first time, that the stereocilia membrane in cochlear hair cells is dynamically regulated by the mechanotransduction channel to impact the membrane mechanical properties. This work provides direct evidence that the opening and closing associated with the MET channel is regulating the membrane viscosity suggesting that the MET ...

Comparative Cochlear Transcriptomics in Echolocating Bats and Mouse Reveals Hras as Protector Against Noise‐Induced Hearing Loss

Advanced Science, EarlyView.
Comparative cochlear transcriptomics of noise‐exposed bats (Miniopterus fuliginosus) and mice reveals bat‐specific protection mechanisms for noise‐induced hearing loss (NIHL), identifying Hras as a key hub regulator. Functional studies in mice show hair‐cell‐specific Hras overexpression significantly reduced hair‐cell damage and NIHL by activating the ...

Early synapsids neurosensory diversity revealed by CT and synchrotron scanning

The Anatomical Record, EarlyView.
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 ...
