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.

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 ...

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.

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

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

Saccades and drifts differentially modulate neuronal activity in V1: Effects of retinal image motion, position, and extraretinal influences [PDF]

open access: yes, 2008
In natural vision, continuously changing input is generated by fast saccadic eye movements and slow drifts. We analyzed effects of fixational saccades, voluntary saccades, and drifts on the activity of macaque V1 neurons.

Visual stimulation of saccades in magnetically tethered Drosophila [PDF]

open access: yes, 2006
Flying fruit flies, Drosophila melanogaster, perform `body saccades', in which they change heading by about 90° in roughly 70 ms. In free flight, visual expansion can evoke saccades, and saccade-like turns are triggered by similar stimuli in tethered ...

Spatial eye–hand coordination during bimanual reaching is not systematically coded in either LIP or PRR [PDF]

open access: yes, 2018
Significance When we reach for something, we also look at it. If we reach for two objects at once, one with each hand, we look first at one and then the other. It is not known which brain areas underlie this coordination.

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 ...

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.
