Ocular stability and set-point adaptation [PDF]

Philosophical Transactions of the Royal Society B: Biological Sciences, 2017
A fundamental challenge to the brain is how to prevent intrusive movements when quiet is needed. Unwanted limb movements such as tremor impair fine motor control and unwanted eye drifts such as nystagmus impair vision. A stable platform is also necessary to launch accurate movements.

Long-term sensorimotor adaptation in the ocular following system of primates. [PDF]

PLoS ONE, 2017
The sudden movement of a wide-field image leads to a reflexive eye tracking response referred to as short-latency ocular following. If the image motion occurs soon after a saccade the initial speed of the ocular following is enhanced, a phenomenon known ...

Human vestibulo-ocular reflex adaptation is frequency selective [PDF]

Journal of Neurophysiology, 2019
The vestibulo-ocular reflex (VOR) is the only system that maintains stable vision during rapid head rotations. The VOR gain (eye/head velocity) can be trained to increase using a vestibular-visual mismatch stimulus. We sought to determine whether low-frequency (sinusoidal) head rotation during training leads to changes in the VOR during high-frequency ...

New advances regarding adaptation of the vestibulo-ocular reflex [PDF]

Journal of Neurophysiology, 2019
This is a review summarizing the development of vestibulo-ocular reflex (VOR) adaptation behavior with relevance to rehabilitation over the last 10 years and examines VOR adaptation using head-on-body rotations, specifically the influence of training target contrast, position and velocity error signal, active vs.

Human Vestibulo-Ocular Reflex Adaptation Training: Time Beats Quantity [PDF]

Journal of the Association for Research in Otolaryngology, 2018
The vestibulo-ocular reflex (VOR) is the main gaze stabilising system during rapid head movements. The VOR is highly plastic and its gain (eye/head velocity) can be increased via training that induces an incrementally increasing retinal image slip error signal to drive VOR adaptation.

Saccade and vestibular ocular motor adaptation [PDF]

Restorative Neurology and Neuroscience, 2010
Purpose: This paper focuses on motor learning within the saccadic and vestibulo-ocular reflex (VOR) oculomotor systems, vital for our understanding how the brain keeps these subsystems calibrated in the presence of disease, trauma, and the changes that invariably accompany normal development and aging.

Developing a Measure to Quantify Ocular Pain Postoperatively: The Adaptation of the Ocular Pain Assessment Survey

Journal of Ophthalmology, 2022
Purpose. Since quantification and communication of ocular pain is important for a healthier patient follow-up and postoperative guidance, reliable measures like the Ophthalmic Pain Assessment Survey (OPAS) are needed to assess the outcome and management ...

The Role of Different Afferent Systems in the Modulation of the Otolith-Ocular Reflex After Long-Term Space Flights

Frontiers in Physiology, 2022
BackgroundThe vestibular (otolith) function is highly suppressed during space flight (SF) and the study of these changes is very important for the safety of the space crew during SF missions.

Unilateral Adaptation of the Human Angular Vestibulo-Ocular Reflex [PDF]

Journal of the Association for Research in Otolaryngology, 2012
A recent study showed that the angular vestibulo-ocular reflex (VOR) can be better adaptively increased using an incremental retinal image velocity error signal compared with a conventional constant large velocity-gain demand (×2). This finding has important implications for vestibular rehabilitation that seeks to improve the VOR response after injury.
