Age-Related Vestibular Loss: Current Understanding and Future Research Directions

Frontiers in Neurology, 2016
The vestibular system sub-serves a number of reflex and perceptual functions, comprising the peripheral apparatus, the vestibular nerve, the brainstem and cerebellar processing circuits, the thalamic relays, and the vestibular cerebral cortical network ...

Prevalence of Stroke and Diagnostic Performance of Emergency MRI in Acute Isolated Dizziness

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Stroke is frequently misdiagnosed in patients presenting with acute isolated dizziness; the optimal imaging modality for this population remains debated. This study aimed to determine the prevalence of stroke among patients with isolated dizziness and to assess the diagnostic accuracy of magnetic resonance imaging (MRI) and computed ...

The vestibular contribution to the head direction cells signal and navigation

Frontiers in Integrative Neuroscience, 2014
Spatial learning and navigation depend on neural representations of location and direction within the environment. These representations, encoded by place cells and head direction cells, respectively, are dominantly controlled by visual cues, but ...

Prediction Model for Etiologic Differentiation of Isolated Vestibular Syndrome in Emergency Settings

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective This study aimed to develop and validate a predictive model for differentiating central from peripheral etiologies in patients with isolated vestibular syndrome (VS). Methods In this multicenter retrospective cohort study, 506 patients with isolated VS from five hospitals were divided into derivation (n = 301) and validation (n = 205)

Quantitative Assessment of Upper Limb Ataxia Using a Virtual Reality‐Based Evaluation System

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Cerebellar ataxia impairs coordination and balance, reducing quality of life. Conventional clinical scales, including the Scale for the Assessment and Rating of Ataxia (SARA) and the International Cooperative Ataxia Rating Scale (ICARS), are widely used to assess ataxia but are limited by subjectivity and inter‐rater variability ...

Possibilities of Inner Ear Barrier Models for Otologic Drug Development

Advanced Therapeutics, EarlyView.
This review examines innovative organ chip models that reconstruct critical inner ear barriers, addressing a fundamental challenge in otologic drug development: the limited understanding of pharmaceutical behavior across these complex barriers. By replicating these barriers, the advanced models offer promising alternatives to traditional testing ...

Electrophysiological Measurements of Peripheral Vestibular Function—A Review of Electrovestibulography

Frontiers in Systems Neuroscience, 2017
Electrocochleography (EcochG), incorporating the Cochlear Microphonic (CM), the Summating Potential (SP), and the cochlear Compound Action Potential (CAP), has been used to study cochlear function in humans and experimental animals since the 1930s ...

Targeting Histamine H4 Receptor in the Rostral Ventromedial Medulla to Relieve Hypertension

Advanced Science, EarlyView.
H4R and its downstream TRPV1 channel mediate the excitatory effect of TMN histaminergic afferent inputs on GABAergic sympathoinhibitory neurons in RVMM. Intranasal delivery of selective H4R agonist VUF 8430 suppresses renal sympathetic outflow and elicits sustained depressor and bradycardia responses in SHRs and CUMS‐induced hypertensive rats ...
