Efficient gaze stabilization during video Active Gaze Shift Test (vAGST) in bilateral vestibulopathy [PDF]
Frontiers in NeurologyIntroductionWhile most head movements in daily life are active, most tools used to assess vestibular deficits rely on passive head movements. A single gain value is not sufficient to quantify gaze stabilization efficiency during active movements in ...

Role of locomotor efference copy in vertebrate gaze stabilization [PDF]
Frontiers in Neural Circuits, 2022 Vertebrate locomotion presents a major challenge for maintaining visual acuity due to head movements resulting from the intimate biomechanical coupling with the propulsive musculoskeletal system.

Complex gaze stabilization in mantis shrimp. [PDF]
Proc Biol Sci, 2018 Almost all animals, regardless of the anatomy of the eyes, require some level of gaze stabilization in order to see the world clearly and without blur. For the mantis shrimp, achieving gaze stabilization is unusually challenging as their eyes have an unprecedented scope for movement in all three rotational degrees of freedom: yaw, pitch and torsion. We

Sensory gaze stabilization in echolocating bats. [PDF]
Proc Biol Sci, 2019 Sensing from a moving platform is challenging for both man-made machines and animals. Animals' heads jitter during movement, so if the sensors they carry are not stabilized, any spatial estimation might be biased. Flying animals, like bats, seriously suffer from this problem because flapping flight induces rapid changes in acceleration which moves the ...

Skill-Related Adaptive Modifications of Gaze Stabilization in Elite and Non-Elite Athletes [PDF]
Frontiers in Sports and Active Living, 2022 The vestibular ocular reflex (VOR) provides gaze stability during head movements by driving eye movements in a direction opposing head motion. Although vestibular-based rehabilitation strategies are available, it is still unclear whether VOR can be ...

Multisensory gaze stabilization in response to subchronic alteration of vestibular type I hair cells [PDF]
eLife, 2023 The functional complementarity of the vestibulo-ocular reflex (VOR) and optokinetic reflex (OKR) allows for optimal combined gaze stabilization responses (CGR) in light. While sensory substitution has been reported following complete vestibular loss, the

The influence of saccades on yaw gaze stabilization in fly flight. [PDF]
PLoS Computational Biology, 2023 In a way analogous to human vision, the fruit fly D. melanogaster and many other flying insects generate smooth and saccadic movements to stabilize and shift their gaze in flight, respectively. It has been hypothesized that this combination of continuous

The Gaze Stabilization Test Following Concussion. [PDF]
J Am Acad Audiol, 2018 Concussion can cause vestibular dysfunction and oculomotor abnormalities which can lead to dizziness and protracted recovery time. There are few clinically useful, functional measures of the vestibulo-ocular reflex (VOR) post-concussion.The purpose of this study was to examine the gaze stabilization test (GST) in those referred for vestibular physical ...

Complementary feedback control enables effective gaze stabilization in animals. [PDF]
Proc Natl Acad Sci U S A, 2022 Significance In visually active animals, eye, head, and body movements are coordinated to direct gaze. Given their distinct mechanics, how does the nervous system weight their contribution? By combining experiments in flying flies with control theory, we show that flies implement an elegant solution to this problem: the lower inertia head is ...
