Seeing and looking: Evidence for developmental and stimulus-dependent changes in infant scanning efficiency.

open access: yesPLoS ONE, 2022
Though previous work has examined infant attention across a variety of tasks, less is known about the individual saccades and fixations that make up each bout of attention, and how individual differences in saccade and fixation patterns (i.e., scanning ...

Dissociable roles of dorsolateral prefrontal cortex and frontal eye fields during saccadic eye movements

open access: yesFrontiers in Human Neuroscience, 2015
The dorsolateral prefrontal cortex (DLPFC) and the frontal eye fields (FEF) have both been implicated in the executive control of saccades, yet possible dissociable roles of each region have not been established.

Saccade generation by the frontal eye fields in rhesus monkeys is separable from visual detection and bottom-up attention shift. [PDF]

open access: yesPLoS ONE, 2012
The frontal eye fields (FEF), originally identified as an oculomotor cortex, have also been implicated in perceptual functions, such as constructing a visual saliency map and shifting visual attention.

Saccadic suppression during voluntary versus reactive saccades

open access: yesJournal of Vision, 2017
Saccades are fast eye movements that reorient gaze. They can be performed voluntarily-for example, when viewing a scene-but they can also be triggered in reaction to suddenly appearing targets. The generation of these voluntary and reactive saccades have been shown to involve partially different cortical pathways.

Association of saccade duration and saccade acceleration/deceleration asymmetry during visually guided saccade in schizophrenia patients. [PDF]

open access: yesPLoS ONE, 2014
OBJECTIVE: To examine the difference between schizophrenia patients and normal controls on velocity and acceleration of saccade, by using the basic visually guided saccade (VGS) paradigm.

Detection of stimulus displacements across saccades is capacity-limited and biased in favor of the saccade target

open access: yesFrontiers in Systems Neuroscience, 2015
Retinal image displacements caused by saccadic eye movements are generally unnoticed. Recent theories have proposed that perceptual stability across saccades depends on a local evaluation process centered on the saccade target object rather than on ...

Visual attention is not deployed at the endpoint of averaging saccades.

open access: yesPLoS Biology, 2018
The premotor theory of attention postulates that spatial attention arises from the activation of saccade areas and that the deployment of attention is the consequence of motor programming.

Bilateral increase in MEG planar gradients prior to saccade onset

open access: yesScientific Reports, 2023
Every time we move our eyes, the retinal locations of objects change. To distinguish the changes caused by eye movements from actual external motion of the objects, the visual system is thought to anticipate the consequences of eye movements (saccades ...

Salient Distractors Can Induce Saccade Adaptation

open access: yesJournal of Ophthalmology, 2014
When saccadic eye movements consistently fail to land on their intended target, saccade accuracy is maintained by gradually adapting the movement size of successive saccades. The proposed error signal for saccade adaptation has been based on the distance

Adaptation of saccadic sequences with and without remapping

open access: yesFrontiers in Human Neuroscience, 2016
It is relatively easy to adapt visually-guided saccades because the visual vector and the saccade vector match. The retinal error at the saccade landing position is compared to the prediction error, based on target location and efference copy.
