Afterimages Reveal Interocular Transfer of Shape Adaptation

open access: yesi-Perception, 2011
An afterimage's shape changes systematically depending on the adapted shape. Adapting to circles produces polygonal afterimages, whereas adapting to hexagons sometimes produce circular afterimages.

Motion transparency : depth ordering and smooth pursuit eye movements [PDF]

open access: yes, 2011
When two overlapping, transparent surfaces move in different directions, there is ambiguity with respect to the depth ordering of the surfaces. Little is known about the surface features that are used to resolve this ambiguity.

THE DARK ADAPTATION OF THE HUMAN EYE [PDF]

open access: yesJournal of General Physiology, 1920
During the dark adaptation of the human eye, its visual threshold decreases to a small fraction of its original value in the light. An analysis of the quantitative data describing this adaptation shows that it follows the course of a bimolecular chemical reaction.

A Neuroanatomically Grounded Optimal Control Model of the Compensatory Eye Movement System in Mice

open access: yesFrontiers in Systems Neuroscience, 2020
We present a working model of the compensatory eye movement system in mice. We challenge the model with a data set of eye movements in mice (n =34) recorded in 4 different sinusoidal stimulus conditions with 36 different combinations of frequency (0.1–3 ...

Simultaneous recordings of ocular microtremor and microsaccades with a piezoelectric sensor and a video-oculography system [PDF]

open access: yesPeerJ, 2013
Our eyes are in continuous motion. Even when we attempt to fix our gaze, we produce so called “fixational eye movements”, which include microsaccades, drift, and ocular microtremor (OMT).

Features of eye movements during rapid automatized naming in Chinese children aged 7–11 years

open access: yesFrontiers in Pediatrics, 2022
Rapid Automatized Naming (RAN) tests have been well-documented to predict reading abilities as well as a variety of neurobiological disorders (e.g., developmental dyslexia).

Preoperative prism adaptation test in normosensoric strabismus [PDF]

open access: yes, 1989
In 19 patients with normosensoric esotropia, the squint angles measured with the alternate cover test were compared with those after prolonged prismatic correction of the squint angle and with those after prolonged occlusion of one eye.

Psychological aspects rehabilitation of patients with anophthalmia

open access: yesOftalʹmologiâ, 2014
This work deals with the psychological rehabilitation of patients with anophthalmia having eye protesis as the main role on the problem. Stages of psychological reaction after eye lost and also the difficulties of adaptation of fellows with both eyesight

THE DARK ADAPTATION OF THE EYE OF THE HONEY BEE [PDF]

open access: yesJournal of General Physiology, 1935
Bees which are held in a fixed position so that only head movements can be made, respond to a moving stripe system in their visual field by a characteristic motion of the antennae. This reflex can be used to measure the bee's state of photic adaptation.
