Frontiers 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.

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

The effect of distractors on saccades and adaptation of saccades in strabismus
Vision Research, 2011 This paper reports two experiments to determine the contribution of the suppressing eye to the generation of saccadic eye movements in constant strabismus. Eye movements were recorded using a Skalar infra-red recorder. Experiment 1 tested six participants with constant strabismus, pathological suppression and no clinically demonstrable binocular single

Separate representations of target and timing cue locations in the supplementary eye fields [PDF]
, 2009 When different stimuli indicate where and when to make an eye movement, the brain areas involved in oculomotor control must selectively plan an eye movement to the stimulus that encodes the target position and also encode the information available from ...

Frontiers 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 ...

There is no attentional global effect: Attentional shifts are independent of the saccade endpoint.
Journal of Vision, 2015 Many studies have found a strong coupling between selective attention and eye movements. The premotor theory of attention suggests that saccade preparation is directly responsible for such attentional shifts.

Saccadic suppression of displacement in face of saccade adaptation
Vision Research, 2011 Saccades challenge visual perception since they induce large shifts of the image on the retina. Nevertheless, we perceive the outer world as being stable. The saccadic system also can rapidly adapt to changes in the environment (saccadic adaptation). In such case, a dissociation is introduced between a driving visual signal (the original saccade target)

Frontiers 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 ...

Pupillometry Reveals the Role of Arousal in a Postexercise Benefit to Executive Function
Brain Sciences, 2021 A single bout of aerobic exercise improves executive function; however, the mechanism(s) underlying this improvement remains unclear. Here, we employed a 20-min bout of aerobic exercise, and at pre- and immediate post-exercise sessions examined executive

Nature of Variability in Saccades [PDF]
Journal 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 ...
