Effect of Saccadic Adaptation on Sequences of Saccades

open access: yesJournal of Eye Movement Research, 2012
Accuracy of saccadic eye movements is maintained thanks to adaptation mechanisms. The adaptive lengthening and shortening of reactive and voluntary saccades rely on partially separate neural substrates.

A Vertical Asymmetry in Saccades [PDF]

open access: yesJournal of Eye Movement Research, 2015
Visual exploration of natural scenes imposes demands that differ between the upper and the lower visual hemifield. Yet little is known about how ocular motor performance is affected by the location of visual stimuli or the direction of a behavioural ...

Systematic diagonal and vertical errors in antisaccades and memory-guided saccades [PDF]

open access: yesJournal of Eye Movement Research, 2010
Studies of memory-guided saccades in monkeys show an upward bias, while studies of antisaccades in humans show a diagonal effect, a deviation of endpoints toward the 45° diagonal.

Saccadic Disinhibition on the Saccade Trace

open access: yesi-Perception, 2011
It has generally thought that information from the eyes is made available during a fixation, but not during a saccade when reading. Some researchers even suggested the duration of saccades should be subtracted from the reading time in eye movement ...

Saccades [PDF]

open access: yes, 2022
Saccades: instruct the patient to make rapid movements of their eyes in each gaze direction, noting the speed, conjugacy, latency, and accuracy. First have the patient look between an eccentric target and the camera horizontally and vertically, making ...

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.

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 ...

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

Enhanced Eye Velocity With Backup Saccades in vHIT Tests of a Menière Disease Patient: A Case Report

open access: yesFrontiers in Surgery, 2021
Reduced eye velocity and overt or covert compensatory saccades during horizontal head impulse testing are the signs of reduced vestibular function. However, here we report the unusual case of a patient who had enhanced eye velocity during horizontal head

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 ...
