Saccades and drifts differentially modulate neuronal activity in V1: Effects of retinal image motion, position, and extraretinal influences [PDF]
, 2008 In natural vision, continuously changing input is generated by fast saccadic eye movements and slow drifts. We analyzed effects of fixational saccades, voluntary saccades, and drifts on the activity of macaque V1 neurons.

Neural representations of covert attention across saccades: comparing pattern similarity to shifting and holding attention during fixation [PDF]
eneuro, 2020 AbstractWe 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.

Aging increases compensatory saccade amplitude in the video head impulse test
Frontiers in Neurology, 2016 Objective: Rotational vestibular function declines with age resulting in saccades as a compensatory mechanism to improve impaired gaze stability. Small reductions in rotational vestibulo-ocular reflex (VOR) gain that would be considered clinically ...

Evaluation of the vestibulo-ocular reflex in patients with chronic otitis media
Brazilian Journal of Otorhinolaryngology, 2022 Introduction: In recent years, scientific evidence has shown that chronic otitis media may cause balance and vestibular dysfunction. Objective: To compare the results of the video head impulse test (gain and symmetry of the vestibulo-ocular reflex and ...

LAG-1: A dynamic, integrative model of learning, attention, and gaze
PLoS ONE, 2022 It is clear that learning and attention interact, but it is an ongoing challenge to integrate their psychological and neurophysiological descriptions. Here we introduce LAG-1, a dynamic neural field model of learning, attention and gaze, that we fit to ...

The reentry hypothesis: The putative interaction of the frontal eye field, ventrolateral prefrontal cortex, and areas V4, IT for attention and eye movement [PDF]
, 2005 Attention is known to play a key role in perception, including action selection, object recognition and memory. Despite findings revealing competitive interactions among cell populations, attention remains difficult to explain.

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 ...

Pre-saccadic perception: separate time courses for enhancement and spatial pooling at the saccade target [PDF]
, 2017 We interact with complex scenes using eye movements to select targets of interest. Studies have shown that the future target of a saccadic eye movement is processed differently by the visual system.

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 ...

The parallel programming of landing position in saccadic eye movement sequences [PDF]
, 2020 Saccadic eye movements occur in sequences, gathering new information about the visual environment to support successful task completion. Here we examine the control of these saccadic sequences and specifically the extent to which the spatial aspects of ...
