Reading Specific Small Saccades Predict Individual Phonemic Awareness and Reading Speed
Frontiers in Neuroscience, 2021 Small fixational eye-movements are a fundamental aspect of vision and thought to reflect fine shifts in covert attention during active viewing. While the perceptual benefits of these small eye movements have been demonstrated during a wide range of ...

What does the video head impulse test tell us about post-caloric vestibular recruitment?
Brazilian Journal of Otorhinolaryngology, 2023 Objective: The vestibular recruitment observed in caloric testing is a new tool in the study of the vestibulo-ocular reflex. This study aimed to determine the sensitivity and specificity of the video head impulse test to detect post-caloric vestibular ...

Frontiers in NeurologyIntroductionAcute 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.

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

Neural representations of covert attention across saccades: comparing pattern similarity to shifting and holding attention during fixation [PDF]
eneuro, 2020 Abstract We can focus visuospatial attention by covertly attending to relevant locations, moving our eyes, or both simultaneously. How does shifting versus holding covert attention during fixation compare with maintaining covert attention across saccades? We acquired fMRI data during a combined saccade and covert attention task. On Eyes-

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 ...

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.

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.

Corrective saccades in acute vestibular neuritis: studying the role of prediction using automated passively-induced head impulses. [PDF]
, 2023 When the demands for visual stabilization during head rotations overwhelm the ability of the vestibulo-ocular reflex (VOR) to produce compensatory eye movements, the brain produces corrective saccades that bring gaze towards the fixation target, even ...

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.
