Vestibular recovery and central compensation after acute unilateral vestibulopathy – changes in saccadic response patterns and gains over time

Frontiers in Neurology
IntroductionAcute 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.

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 ...

Neural differences between covert and overt attention studied using EEG with simultaneous remote eye tracking

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

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.

The evolution of covert, silent infection as a parasite strategy [PDF]

, 2009
Many parasites and pathogens cause silent/covert infections in addition to the more obvious infectious disease-causing pathology. Here, we consider how assumptions concerning superinfection, protection and seasonal host birth and transmission rates ...

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.

Covert research and adult protection and safeguarding: An ethical dilemma? [PDF]

, 2014
Purpose: This paper aims to consider the contentious issue of covert research in studying the social contexts of vulnerable groups. It explores its potential utility in areas where overt strategies may be problematic or denied; and examines and ...

A 3D‐Printed SFE‐Graded Alloy Mitigates Cryogenic Discontinuous Plastic Flow and Hydrogen Embrittlement

Advanced Science, EarlyView.
A novel strategy features gradient composition and stacking fault energy‐tuned (CoCrMn)100‐2xFexNix fabricated via in situ alloying additive manufacturing. This design circumvents cryogenic discontinuous plastic flow and hydrogen embrittlement of metallic materials under quasi‐static loading and hydrogen‐rich environment relevant to lunar polar ...

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 ...
