THE INFLUENCE OF LIGHT ADAPTATION ON SUBSEQUENT DARK ADAPTATION OF THE EYE [PDF]

open access: yesJournal of General Physiology, 1937
The course of dark adaptation of the human eye varies with the intensity used for the light adaptation which precedes it. Preadaptation to intensities below 200 photons is followed only by rod adaptation, while preadaptation to intensities above 4000 photons is followed first by cone adaptation and then by rod adaptation. With increasing

Saccadic Adaptation Is Associated with Starting Eye Position

open access: yesFrontiers in Human Neuroscience, 2016
Saccadic adaptation is the motor learning process that keeps saccade amplitudes on target. This process is eye position specific: amplitude adaptation that is induced for a saccade at one particular location in the visual field transfers incompletely to ...

Dna methylation dynamics associated with visual system remodeling during flatfish metamorphosis [PDF]

open access: yesEpigenetics & Chromatin
Background Flatfish metamorphosis involves dramatic tissue remodeling, including the migration of one eye to the opposite side of the body, enabling the transition from pelagic to benthic life.

No evidence for differential saccadic adaptation in children and adults with an autism spectrum diagnosis

open access: yesFrontiers in Integrative Neuroscience, 2023
BackgroundAltered patterns of eye-movements during scene exploration, and atypical gaze preferences in social settings, have long been noted as features of the Autism phenotype. While these are typically attributed to differences in social engagement and

Rapid visual adaptation persists across saccades

open access: yesiScience, 2021
Summary: Neurons in the visual cortex quickly adapt to constant input, which should lead to perceptual fading within few tens of milliseconds. However, perceptual fading is rarely observed in everyday perception, possibly because eye movements refresh ...

The dynamics of light adaptation in Ascalaphus (Libelloides macaronius; Neuroptera)

open access: yesActa Biologica Slovenica, 2007
The owl-fly or Ascalaphus (Libelloides macaronius; Neuroptera) is an insect with a UV-sensitive superposition eye. Although optical superposition is mainly a feature of dusk/dark active animals, this is a predator living and hunting in bright sunlight ...

Network adaptation improves temporal representation of naturalistic stimuli in drosophila eye: II Mechanisms [PDF]

open access: yes, 2009
Retinal networks must adapt constantly to best present the ever changing visual world to the brain. Here we test the hypothesis that adaptation is a result of different mechanisms at several synaptic connections within the network.

Motor learning by selection in visual working memory

open access: yesScientific Reports, 2021
Motor adaptation maintains movement accuracy over the lifetime. Saccadic eye movements have been used successfully to study the mechanisms and neural basis of adaptation. Using behaviorally irrelevant targets, it has been shown that saccade adaptation is

Electrooculography-based continuous eye-writing recognition system for efficient assistive communication systems. [PDF]

open access: yesPLoS ONE, 2018
Human-computer interface systems whose input is based on eye movements can serve as a means of communication for patients with locked-in syndrome. Eye-writing is one such system; users can input characters by moving their eyes to follow the lines of the ...
