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

Saccade metrics reflect decision-making dynamics during urgent choices
Nature Communications, 2018 A perceptual judgment is typically characterized by constructing psychometric and chronometric functions, i.e., by mapping the accuracies and reaction times of motor choices as functions of a sensory stimulus feature dimension. Here, we show that various

Vision 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.

Biases in the perceived timing of perisaccadic perceptual and motor events [PDF]
, 2006 Subjects typically experience the temporal interval immediately following a saccade as longer than a comparable control interval. One explanation of this effect is that the brain antedates the perceptual onset of a saccade target to around the time of ...

PLoS 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 ...

Instantaneous Midbrain Control of Saccade Velocity
Journal of Neuroscience, 2018 The ability to interact with our environment requires the brain to transform spatially represented sensory signals into temporally encoded motor commands for appropriate control of the relevant effectors.

Effect of Saccadic Adaptation on Sequences of Saccades
Journal 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. Although in daily-life we mostly perform sequences of saccades, the effect of saccadic adaptation has been mainly evaluated on single saccades.

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

Bilateral increase in MEG planar gradients prior to saccade onset
Scientific 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 ...

Sampling rate influences saccade detection in mobile eye tracking of a reading task
Journal of Eye Movement Research, 2017 The purpose of this study was to compare saccade detection characteristics in two mobile eye trackers with different sampling rates in a natural task. Gaze data of 11 participants were recorded in one 60 Hz and one 120 Hz mobile eye tracker and compared ...
