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.

Nature of Variability in Saccades [PDF]

open access: yesJournal of Neurophysiology, 2003
We studied the variability in saccades by comparing the peak velocities of saccades with the same target amplitude made with different actual amplitudes. We tested three hypotheses: the pulse-height noise hypothesis (peak velocity and amplitude vary proportionally), the localization noise hypothesis (variability in amplitude and peak velocity lie ...

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 ...

Saccadic inhibition in a guided saccade task

open access: yesPeerJ, 2018
The eye movement system reacts very systematically to visual transients that are presented during the planning phase of a saccade. About 50 to 70 ms after the onset of a transient, the number of saccades that are started decreases, a phenomenon that has been termed saccadic inhibition.

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 research.

Pupil dynamics reveal preparatory processes in the generation of pro-saccades and anti-saccades in open skill sports athletes

open access: yesBiology of Sport
This study investigated pupil dynamics to establish a physiological index of mental processes associated with executive functioning, enabling objective evaluation of cognitive load during training to improve understanding of cognitive control in sport ...

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 ...

Distinctive visual tasks for characterizing mild cognitive impairment and dementia using oculomotor behavior

open access: yesFrontiers in Aging Neuroscience, 2023
IntroductionOne’s eye movement (in response to visual tasks) provides a unique window into the cognitive processes and higher-order cognitive functions that become adversely affected in cases with cognitive decline, such as those mild cognitive ...

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
