Human frontal eye fields and spatial priming of pop-out [PDF]
, 2007 "Priming of pop-out" is a form of implicit memory that facilitates detection of a recently inspected search target. Repeated presentation of a target's features or its spatial position improves detection speed (feature/spatial priming).

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 ...

Video_1_Enhanced Eye Velocity With Backup Saccades in vHIT Tests of a Menière Disease Patient: A Case Report.MOV [PDF]
, 2021 Reduced eye velocity and overt or covert compensatory saccades during horizontal head impulse testing are the signs of reduced vestibular function. However, here we report the unusual case of a patient who had enhanced eye velocity during horizontal head

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 ...

Head impulses in complete bilateral vestibular loss: Catch-up saccades require visual input [PDF]
, 2013 Patients with bilateral vestibular loss (BVL) experience oscillopsia during passive head movements,(1) e.g., walking or driving. Because their vestibulo-ocular reflex does not stabilize gaze with compensatory eye movements, patients with 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-

Ocular drift along the mental number line [PDF]
, 2016 We examined the spontaneous association between numbers and space by documenting attention deployment and the time course of associated spatial-numerical mapping with and without overt oculomotor responses.

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 ...
