The Effect of Vestibulo-Ocular Reflex Deficits and Covert Saccades on Dynamic Vision in Opioid-Induced Vestibular Dysfunction [PDF]
PLoS ONE, 2014 Patients with bilateral vestibular dysfunction cannot fully compensate passive head rotations with eye movements, and experience disturbing oscillopsia.

The Role of Neck Input in Producing Corrective Saccades in the Head Impulse Test
Frontiers in Neurology, 2022 BackgroundThe head impulse test is a valuable clinical test that can help identify peripheral vestibular dysfunction by observing corrective saccades that return the eyes to the target of interest.

Compensatory Saccade in the Vestibular Impaired Monkey
Frontiers in Neurology, 2023 IntroductionLoss of the vestibulo-ocular reflex (VOR) affects visual acuity during head movements. Patients with unilateral and bilateral vestibular deficits often use saccadic eye movements to compensate for an inadequate VOR.

Information-optimal local features automatically attract covert and overt attention [PDF]
Scientific Reports, 2022 In fast vision, local spatial properties of the visual scene can automatically capture the observer’s attention. We used specific local features, predicted by a constrained maximum-entropy model to be optimal information-carriers, as candidate “salient ...

Frontiers in Neurology, 2021 Background: Functional head impulse test (fHIT) tests the ability of the vestibulo-ocular reflex (VOR) to allow visual perception during head movements. Our previous study showed that active head movements to the side with a vestibular lesion generated a

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 ...

Video head impulse test in bilateral vestibulopathy
Brazilian Journal of Otorhinolaryngology, 2022 Introduction: Bilateral vestibulopathy is a rare chronic condition with multiple etiologies. Bilateral vestibulopathy is characterized mainly by unsteadiness when walking or standing, which worsens in darkness, as well as oscillopsia.

Counterproductive effect of saccadic suppression during attention shifts. [PDF]
PLoS ONE, 2014 During saccadic eye movements, the processing of visual information is transiently interrupted by a mechanism known as "saccadic suppression" [1] that is thought to ensure perceptual stability [2]. If, as proposed in the premotor theory of attention [3],

Enhanced Eye Velocity With Backup Saccades in vHIT Tests of a Menière Disease Patient: A Case Report
Frontiers in Surgery, 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

Perceptual decisions interfere more with eye movements than with reach movements
Communications Biology, 2023 Perceptual judgements are formed through invisible cognitive processes. Reading out these judgements is essential for advancing our understanding of decision making and requires inferring covert cognitive states based on overt motor actions.
