Downbeat nystagmus: aetiology and comorbidity in 117 patients [PDF]

, 2008
Objectives: Downbeat nystagmus (DBN) is the most common form of acquired involuntary ocular oscillation overriding fixation. According to previous studies, the cause of DBN is unsolved in up to 44% of cases.

Fish welfare in a changing world: New developments and current challenges

Journal of Fish Biology, EarlyView.
Abstract The welfare of non‐human animals is central to ethical discussions on animal use, with increasing attention to fish welfare across research, aquaria, aquaculture, and fisheries. This paper reviews current theoretical approaches to animal welfare and recent advances in defining and assessing fish welfare since the seminal paper by Huntingford ...

Volitional control of anticipatory ocular smooth pursuit after viewing, but not pursuing, a moving target: evidence for a re-afferent velocity store [PDF]

, 1997
Although human subjects cannot normally initiate smooth eye movements in the absence of a moving target, previous experiments have established that such movements can be evoked if the subject is required to pursue a regularly repeated, transient target ...

Welfare and Physiological Consequences of Non‐Lethal Blood Sampling From the Caudal Vasculature of Atlantic Salmon (Salmo salar L.)

Journal of Fish Diseases, EarlyView.
ABSTRACT The objective of this study was to evaluate welfare and health effects following single and repeated non‐lethal blood sampling from the caudal vasculature of Atlantic salmon. Two experiments were conducted at three different temperatures: a 6‐week freshwater experiment with fish weighing 50–100 g, undergoing up to four blood withdrawals, and a

Manual head rotation synchronised to a metronome is a feasible and valid method for assessing visually enhanced vestibulo-ocular reflexes and vestibulo-ocular reflex suppression

Frontiers in Neurology
IntroductionThe visually enhanced vestibulo-ocular reflex (VVOR) and vestibulo-ocular reflex suppression (VOR-S) are critical in evaluating vestibular and cerebellar contributions to oculomotor control. This study aimed to investigate the feasibility and

Plasticity within non-cerebellar pathways rapidly shapes motor performance in vivo

Nature Communications, 2016
The extent to which non-cerebellar pathways can refine motor performance is debated. Here, the authors demonstrate behaviourally relevant patterns of activation evoke rapid plasticity within direct and indirect vestibulo-ocular reflex pathways in vivo ...

A Core Head, Neck, and Neuroanatomy Syllabus for Physical Therapy Student Education

Clinical Anatomy, Volume 39, Issue 4, Page 436-460, May 2026.
ABSTRACT Head, neck, and neuroanatomy are essential components of physical therapy education due to their broad clinical applications. Detailed syllabi exist for medical students, yet none have been developed for physical therapy. This study aimed to produce an International Federation of Associations of Anatomists core head, neck, and neuroanatomy ...

Vestibulo-Ocular Reflex Suppression: Clinical Relevance and Assessment in the Digital Age

Digital Biomarkers
Background: Visual acuity and image stability are crucial for daily activities, particularly during head motion. The vestibulo-ocular reflex (VOR) and its suppression (VORS) support stable fixation of objects of interest.

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.

Migraine patients consistently show abnormal vestibular bedside tests

Arquivos de Neuro-Psiquiatria, 2015
Migraine and vertigo are common disorders, with lifetime prevalences of 16% and 7% respectively, and co-morbidity around 3.2%. Vestibular syndromes and dizziness occur more frequently in migraine patients.
