MRI and Implant Safety at Low‐Field and Ultralow‐Field Strengths

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Despite its unequivocal value in radiological diagnosis, access to conventional high‐field MRI systems remains extremely uneven across the world. Access is particularly limited in underfunded and remote settings, due to the high cost and infrastructure requirements of MRI systems.

Vestibular Evoked Myogenic Potentials to Diagnose Vestibular Neuritis: A Scoping Review

The Laryngoscope, EarlyView.
Standardization of stimulation and recording protocols is essential to improve comparability across VEMP studies. Integrating cervical and ocular VEMPs with other vestibular tests enhances diagnostic accuracy and supports precise localization of vestibular neuritis.

Spontaneous Nystagmus in the Dark in an Infantile Nystagmus Patient May Represent Negative Optokinetic Afternystagmus

Frontiers in Neurology, 2018
Abnormal projection of the optic nerves to the wrong cerebral hemisphere transforms the optokinetic system from its usual negative feedback loop to a positive feedback loop with characteristic ocular motor instabilities including directional reversal of ...

Vestibular Dysfunction in Parkinson's Disease: A Systematic Review of Signs and Symptoms

Movement Disorders Clinical Practice, EarlyView.
Abstract Background Despite the growing interest in the link between Parkinson's disease (PD) neuropathology and vestibular system, there is still a lack of consensus about the presence of vestibular dysfunctions in PD. Objective This review aims to identify vestibular signs and symptoms reported in PD patients and to summarize and critically appraise ...

Visual suppression of the vestibulo-ocular reflex during space flight [PDF]

Visual suppression of the vestibulo-ocular reflex was studied in 16 subjects on 4 Space Shuttle missions. Eye movements were recorded by electro-oculography while subjects fixated a head mounted target during active sinusoidal head oscillation at 0.3 Hz.

Ocular Motor Abnormalities in Functional Neurological Disorder: A Video‐Oculography Study

Movement Disorders Clinical Practice, EarlyView.
Abstract Background Functional neurological disorders (FND) can include various sensory, motor or cognitive symptoms. Eye movement recordings, measured through video‐oculography, could serve as biomarkers for characterizing these dysfunctions in FND.
