The cat's vestibulo‐ocular reflex.

The Journal of Physiology, 1980
1. The conscious cat's vestibulo‐ocular reflex (v.o.r.) has been studied using the electro‐oculogram to measure eye movements. A servomotor was used to rotate the head horizontally while the body remained stationary. 2. The frequency content of natural head movements in the cat has been determined by Fourier analysis.

Differential regulations of vestibulo-ocular reflex and optokinetic response by β- and α2-adrenergic receptors in the cerebellar flocculus

Scientific Reports, 2017
Norepinephrine modulates synaptic plasticity in various brain regions and is implicated in memory formation, consolidation and retrieval. The cerebellum is involved in motor learning, and adaptations of the vestibulo-ocular reflex (VOR) and optokinetic ...

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

Clinical Anatomy, EarlyView.
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 ...

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.

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 ...

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 ...

The Interaction of Pre-programmed Eye Movements With the Vestibulo-Ocular Reflex

Frontiers in Systems Neuroscience, 2018
The Vestibulo-Ocular Reflex (VOR) works to stabilize gaze during unexpected head movements. However, even subjects who lack a VOR (e.g., vestibulopathic patients) can achieve gaze stability during planned head movements by using pre-programmed eye ...

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.

Chinese Clinical Practice Guidelines for Auditory Neuropathy (gCAN)

World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Auditory neuropathy (AN) is an auditory disorder that affects the function of the auditory pathway. An increasing number of AN cases have been identified with the revelation of the underlying mechanisms, the advancements of diagnostic and detecting techniques.

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.
