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

Atypical modulation of face-elicited saccades in autism spectrum disorder in a double-step saccade paradigm [PDF]

open access: yes, 2011
Atypical development of face processing is a major characteristic in autism spectrum disorder (ASD), which could be due to atypical interactions between subcortical and cortical face processing. The current study investigated the saccade planning towards

The Role of Neck Input in Producing Corrective Saccades in the Head Impulse Test

open access: yesFrontiers in Neurology, 2022
BackgroundThe head impulse test is a valuable clinical test that can help identify peripheral vestibular dysfunction by observing corrective saccades that return the eyes to the target of interest.

Binocular coordination of saccades: development, aging and cerebral substrate

open access: yesJournal of Eye Movement Research, 2008
The origin of binocular coordination of saccades (central, peripheral) and the role of learning remain controversial (Hering vs Helmholtz). We will present evidence for learning: in young children (5 years) horizontal saccades are poorly yoked ...

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 ...

Modulation of saccade trajectories during sequential saccades

open access: yesJournal of Neurophysiology, 2021
We show that in saccade sequences, saccade trajectory is modulated in the direction of the preceding saccade and away from the following saccade. The magnitude of this effect is correlated with preceding and following saccade amplitude. This confirms that programming of sequential saccades overlaps.

Systematic diagonal and vertical errors in antisaccades and memory-guided saccades

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.

Saccades in children

open access: yesVision Research, 2006
Saccades are necessary for optimal vision. Little is known about saccades in children. We recorded saccades using an infrared eye tracker in 39 children, aged 8-19 years. Participants made saccades to visual targets that stepped 10 degrees or 15 degrees horizontally and 5 degrees or 10 degrees vertically at unpredictable time intervals.

Looking for discriminating is different from looking for looking's sake. [PDF]

open access: yesPLoS ONE, 2012
Recent studies provide evidence for task-specific influences on saccadic eye movements. For instance, saccades exhibit higher peak velocity when the task requires coordinating eye and hand movements.
