The reentry hypothesis: linking eye movements to visual perception [PDF]

, 2003
Cortical organization of vision appears to be divided into perception and action. Models of vision have generally assumed that eye movements serve to select a scene for perception, so action and perception are sequential processes.

Vestibular recovery and central compensation after acute unilateral vestibulopathy – changes in saccadic response patterns and gains over time

Frontiers in Neurology
IntroductionAcute unilateral vestibulopathy (AUVP), or vestibular neuritis, disrupts the vestibulo-ocular reflex (VOR), leading to impaired gaze stability during head movements. Vestibular function typically recovers to some extent.

Neural differences between covert and overt attention studied using EEG with simultaneous remote eye tracking

Frontiers in Human Neuroscience, 2016
Research on neural mechanisms of attention has generally instructed subjects to direct attention covertly while maintaining fixed gaze. This study combined simultaneous eye tracking and EEG to measure neural attention responses during exogenous cueing in

Saccade metrics reflect decision-making dynamics during urgent choices

Nature Communications, 2018
Saccades have been extensively used to report choices in perceptual decision making studies yet little is known about the influence of covert decision-related processes on saccade metrics.

Vision, perception, and attention through the lens of microsaccades: mechanisms and implications

Frontiers in Systems Neuroscience, 2015
Microsaccades are small saccades. Neurophysiologically, microsaccades are generated using similar brainstem mechanisms as larger saccades. This suggests that peri-saccadic changes in vision that accompany large saccades might also be expected to ...

Covert anti-compensatory quick eye movements during head impulses. [PDF]

PLoS ONE, 2014
BACKGROUND: Catch-up saccades during passive head movements, which compensate for a deficient vestibulo-ocular reflex (VOR), are a well-known phenomenon.

Representation, space and Hollywood Squares: Looking at things that aren't there anymore [PDF]

, 2000
It has been argued that the human cognitive system is capable of using spatial indexes or oculomotor coordinates to relieve working memory load (Ballard, Hayhoe, Pook & Rao, 1997) track multiple moving items through occlusion (Scholl & Pylyshyn, 1999) or

The behavioural and neurophysiological modulation of microsaccades in monkeys

Journal of Eye Movement Research, 2009
Systematic modulations of microsaccades have been observed in humans during covert orienting. We show here that monkeys are a suitable model for studying the neurophysiology governing these modulations of microsaccades.

Task-demands can immediately reverse the effects of sensory-driven saliency in complex visual stimuli [PDF]

, 2008
In natural vision both stimulus features and task-demands affect an observer's attention. However, the relationship between sensory-driven (“bottom-up”) and task-dependent (“top-down”) factors remains controversial: Can task-demands counteract strong ...

The programming of sequences of saccades [PDF]

, 2019
Saccadic eye movements move the high-resolution fovea to point at regions of interest. Saccades can only be generated serially (i.e., one at a time). However, what remains unclear is the extent to which saccades are programmed in parallel (i.e., a series
