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.

Adaptation of Ocular Opponency Neurons Mediates Attention-Induced Ocular Dominance Plasticity

Neuroscience Bulletin, 2023
Previous research has shown that ocular dominance can be biased by prolonged attention to one eye. The ocular-opponency-neuron model of binocular rivalry has been proposed as a candidate account for this phenomenon. Yet direct neural evidence is still lacking. By manipulating the contrast of dichoptic testing gratings, here we measured the steady-state

Simulated annealing in ocular adaptive optics

Optics Letters, 2006
We present what is to our knowledge a first hardware realization of a simulated annealing algorithm in an adaptive optics system designed to image the retina of the human eye. The algorithm is applied to the retinal image itself without the need for wavefront sensors in the system.

Simulation of adaptive mechanisms in the vestibulo-ocular reflex

Biological Cybernetics, 1992
The vestibulo-ocular reflex (VOR), which stabilizes the eyes in space during head movements, can undergo adaptive modification to maintain retinal stability in response to natural or experimental challenges. A number of models and neural sites have been proposed to account for this adaptation but these do not fully explain how the nervous system can ...

Vergence-dependent adaptation of the vestibulo-ocular reflex

Experimental Brain Research, 2003
The gain of the vestibulo-ocular reflex (VOR) normally depends on the distance between the subject and the visual target, but it remains uncertain whether vergence angle can be linked to changes in VOR gain through a process of context-dependent adaptation.

Adaptive plasticity in the otolith-ocular reflex

Auris Nasus Larynx, 2003
This review focuses on the plasticity in the vestibulo-ocular reflex (VOR), especially in the otolith-ocular reflex (OOR). The VOR is a mechanism for the production of rapid compensatory eye movements during head movements. The VOR is under adaptive control which corrects VOR performance when visual-vestibular mismatch arises during head movements.

Short-term adaptation of the cervico-ocular reflex

Experimental Brain Research, 2004
The cervico-ocular reflex (COR) works in conjunction with the vestibulo-ocular reflex (VOR) and the optokinetic reflex (OKR) in order to prevent visual slip over the retina during head movement. The COR induces eye movements in response to proprioceptive signals from the neck.

Ocular cataract and seawater adaptation in salmonids

Aquaculture, 1987
Abstract Formation of ocular cataracts after seawater (SW) exposure of yearling coho salmon has been studied in relation to the parr-smolt transformation. No ocular opacity was observed in fish in fresh water (FW). In February and March, survival rates 12 h after exposure to SW were 11 and 20%, respectively, and cataracts were observed in all ...

Adaptation of ocular vergence to stimulation with large disparities

Experimental Brain Research, 1987
Ocular vergence movements were measured with a scleral coil technique under stabilized viewing conditions for disparity. Crossed disparity steps, ranging between 0.25 and 10 deg, of three different targets were imposed. Ocular vergence responses consisted of converging movements with an initially constant velocity.
