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 ...

Dopamine and impairment at the executive level. [PDF]

open access: yes, 1999
Patients with schizophrenia have an impairment in the inhibition of reflexive saccades, as a consequence of a functional impairment of the prefrontal cortex, which has not yet been encapsulated in terms of a formal model.

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.

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.

Geometry of Saccades and Saccadic Cycles

open access: yes, 2023
The paper is devoted to the development of the differential geometry of saccades and saccadic cycles. We recall an interpretation of Donder's and Listing's law in terms of the Hopf fibration of the $3$-sphere over the $2$-sphere. In particular, the configuration space of the eye ball (when the head is fixed) is the 2-dimensional hemisphere $S^+_L ...

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).

Saccades of video head impulse test in Meniere's disease and Vestibular Migraine: What can we learn from?

open access: yesJournal of Otology, 2023
Background: Saccades are often observed on video head impulse tests (vHIT) in patients with Meniere's Disease (MD) and Vestibular Migraine (VM). However, their saccadic features are not fully described. Objective: This study aims to identify the saccades

Sports athletes use predictive saccades! But why? [PDF]

open access: yes, 2021
In sports, high-level athletes are able to predict the actions of an opposing player. Interestingly, such predictions are also reflected by the athlete’s gaze behaviour. In cricket, for example, a bowler bowls the ball in the direction of a batsman.
