A Novel Saccadic Strategy Revealed by Suppression Head Impulse Testing of Patients with Bilateral Vestibular Loss

open access: yesFrontiers in Neurology, 2017
ObjectiveWe examined the eye movement response patterns of a group of patients with bilateral vestibular loss (BVL) during suppression head impulse testing.

Visuo-tactile links in covert exogenous spatial attention remap across changes in unseen hand posture [PDF]

open access: yes, 2002
We investigated the effect of unseen hand posture on cross-modal, visuo-tactile links in covert spatial attention. In Experiment 1, a spatially nonpredictive visual cue was presented to the left or right hemifleld shortly before a tactile target on ...

Compensatory saccades benefit from prediction during head impulse testing in early recovery from vestibular deafferentation [PDF]

open access: yes, 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.

Aging increases compensatory saccade amplitude in the video head impulse test

open access: yesFrontiers 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

open access: yesBrazilian 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 ...

Diagnosing Covert A-Movement

open access: yes, 2011
Covert movement is movement that is not phonologically visible in the syntactic derivation. While covert A'-movement is widely proposed, covert A-movement is quite uncommon and difficult to identify.

LAG-1: A dynamic, integrative model of learning, attention, and gaze

open access: yesPLoS 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 ...

Covert oculo-manual coupling induced by visually guided saccades.

open access: yesFrontiers in Human Neuroscience, 2013
Hand pointing to objects under visual guidance is one of the most common motor behaviors in everyday life. In natural conditions, gaze and arm movements are commonly aimed at the same target and the accuracy of both systems is considerably enhanced if ...

Reading Specific Small Saccades Predict Individual Phonemic Awareness and Reading Speed

open access: yesFrontiers 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 ...

What does the video head impulse test tell us about post-caloric vestibular recruitment?

open access: yesBrazilian 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 ...
