Video_2_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

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.

Compensatory saccades benefit from prediction during head impulse testing in early recovery from vestibular deafferentation [PDF]
, 2016 The head impulse test (HIT) can identify a deficient vestibulo-ocular reflex (VOR) by the compensatory saccade (CS) generated once the head stops moving.

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.

ERP correlates of shared control mechanisms involved in saccade preparation and in covert attention
Brain Research, 2007 We investigated whether attention shifts and eye movement preparation are mediated by shared control mechanisms, as claimed by the premotor theory of attention. ERPs were recorded in three tasks where directional cues presented at the beginning of each trial instructed participants to direct their attention to the cued side without eye movements ...

Advanced Science, EarlyView.This study presents an anatomical landmark‐guided DRL framework for autonomous wireless capsule endoscopy navigation. Using a lightweight edge‐contour‐depth fusion module, it achieves over 97% coverage across diverse gastric anatomies. To ensure reliability, a two‐stage sim‐to‐real pipeline with an adaptive dynamic programming controller mitigates ...

Atypical disengagement from faces and its modulation by the control of eye fixation in children with Autism Spectrum Disorder [PDF]
, 2010 By using the gap overlap task, we investigated disengagement from faces and objects in children (9–17 years old) with and without autism spectrum disorder (ASD) and its neurophysiological correlates.

Distinct causal influences of parietal versus frontal areas on human visual cortex: evidence from concurrent TMS-fMRI [PDF]
, 2010 It has often been proposed that regions of the human parietal and/or frontal lobe may modulate activity in visual cortex, for example, during selective attention or saccade preparation.

A new tool for investigating the functional testing of the VOR
Frontiers in Neurology, 2013 Peripheral vestibular function may be tested quantitatively, by measuring the gain of the angular vestibulo-ocular reflex (aVOR), or functionally, by assessing how well the aVOR performs with respect to its goal of stabilizing gaze in space and thus ...
