Saccadic inhibition in a guided saccade task [PDF]

open access: yesPeerJ, 2018
The eye movement system reacts very systematically to visual transients that are presented during the planning phase of a saccade. About 50 to 70 ms after the onset of a transient, the number of saccades that are started decreases, a phenomenon that has ...

Analysis of Saccade Characteristics During Fusional Vergence Tests in Normal Binocular Vision Participants [PDF]

open access: yesJournal of Eye Movement Research
The purpose of the study was to analyze, characterize, and compare the measurements of saccades that occurred during the positive and negative fusional vergence test (PFV and NFV, respectively) as a function of the disparity vergence demand.

Compensatory saccade in the vestibular impaired monkey

open access: yesFrontiers in Neurology, 2023
IntroductionLoss of the vestibulo-ocular reflex (VOR) affects visual acuity during head movements. Patients with unilateral and bilateral vestibular deficits often use saccadic eye movements to compensate for an inadequate VOR.

Evolution of eye movement abnormalities in Huntington’s disease

open access: yesAnnals of Movement Disorders, 2022
Huntington’s disease (HD) is an autosomal dominant neurodegenerative disorder. Eye movement abnormalities are characteristic manifestations of HD. The clinical manifestations and eye movement disturbances progress with the natural course of illness.

Characteristics of vestibular corrective saccades in patients with slow visual saccades, vestibular disorders and controls: A descriptive analysis. [PDF]

open access: yesPLoS ONE, 2018
Our aim was to determine whether overt catch up saccades (OS) provoked by vestibular stimuli, as observed in the video head impulse test (vHIT), have comparable metrics as visually triggered horizontal saccades (VS), indicating a common saccadic ...

An fMRI Investigation of Preparatory Set in the Human Cerebral Cortex and Superior Colliculus for Pro- and Anti-Saccades. [PDF]

open access: yesPLoS ONE, 2016
Previous studies have identified several cortical regions that show larger BOLD responses during preparation and execution of anti-saccades than pro-saccades.

Analysis of video head impulse test saccades data in patients with vestibular migraine or probable vestibular migraine

open access: yesJournal of Otology, 2022
Objective: Saccades accompanied by normal gain in video head impulse tests (vHIT) are often observed in patients with vestibular migraine (VM). However, they are not considered as an independent indicator, reducing their utility in diagnosing VM.

Saccades and handedness interact to affect scene memory [PDF]

open access: yesPeerJ, 2018
Repetitive saccades benefit memory when executed before retrieval, with greatest effects for episodic memory in consistent-handers. Questions remain including how saccades affect scene memory, an important visual component of episodic memory. The present

Freezing of saccades in dopa-responsive parkinsonian syndrome

open access: yesAmerican Journal of Ophthalmology Case Reports, 2021
Purpose: Ocular motor abnormalities such as abnormal saccades are common in idiopathic Parkinson's disease (PD) and atypical parkinsonian syndrome, such as progressive supranuclear palsy (PSP) and corticobasal degeneration (CBD).

Bilateral lesion of the cerebellar fastigial nucleus: Effects on smooth pursuit acceleration and non-reflexive visually-guided saccades

open access: yesFrontiers in Neurology, 2022
Background“Central dizziness” due to acute bilateral midline cerebellar disease sparing the posterior vermis has specific oculomotor signs. The oculomotor region of the cerebellar fastigial nucleus (FOR) crucially controls the accuracy of horizontal ...
