Dissociable roles of human frontal eye fields and early visual cortex in presaccadic attention
Nature Communications, 2023 Shortly before saccadic eye movements, visual sensitivity at the saccade target is enhanced, at the expense of sensitivity elsewhere. Some behavioral and neural correlates of this presaccadic shift of attention resemble those of covert attention ...

Coordination of pupil and saccade responses by the superior colliculus
bioRxiv, 2020 The appearance of a salient stimulus evokes saccadic eye movements and pupil dilation as part of the orienting response. Although the role of the superior colliculus (SC) in saccade and pupil dilation has been established separately, whether and how ...

Regularities in vertical saccadic metrics: new insights, and future perspectives
Frontiers in Psychology, 2023 IntroductionAsymmetries in processing by the healthy brain demonstrate regularities that facilitate the modeling of brain operations. The goal of the present study was to determine asymmetries in saccadic metrics during visual exploration, devoid of ...

Saccade target selection and object recognition: evidence for a common attentional mechanism.
Vision Research, 1996 The spatial interaction of visual attention and saccadic eye movements was investigated in a dual-task paradigm that required a target-directed saccade in combination with a letter discrimination task.

Visual mislocalization during double-step saccades
Frontiers in Systems Neuroscience, 2015 Visual objects presented briefly at the time of saccade onset appear compressed toward the saccade target. Compression strength depends on the presentation of a visual saccade target signal and is strongly reduced during the second saccade of a double ...

Saccadic adaptation in 10-41 month-old children
Frontiers in Human Neuroscience, 2016 When saccade amplitude becomes systematically inaccurate, adaptation mechanisms gradually decrease or increase it until accurate saccade targeting is recovered. Adaptive shortening and adaptive lengthening of saccade amplitude rely on separate mechanisms

Adaptation and mislocalization fields for saccadic outward adaptation in humans
Journal of Eye Movement Research, 2010 Adaptive shortening of a saccade influences the metrics of other saccades within a spatial window around the adapted target. Within this adaptation field visual stimuli presented before an adapted saccade are mislocalized in proportion to the change of ...

Human-level saccade detection performance using deep neural networks
bioRxiv, 2018 Saccades are ballistic eye movements that rapidly shift gaze from one location of visual space to another. Detecting saccades in eye movement recordings is important not only for studying the neural mechanisms underlying sensory, motor, and cognitive ...

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

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 ...
