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 ...

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

Age-related decline of online visuomotor adaptation: a combined effect of deteriorations of motor anticipation and execution

open access: yesFrontiers in Aging Neuroscience, 2023
The literature has established that the capability of visuomotor adaptation decreases with aging. However, the underlying mechanisms of this decline are yet to be fully understood.

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 ...

Optical coherence tomography in healthy human subjects in the setting of prolonged dark adaptation

open access: yesScientific Reports, 2023
Human studies have established that short periods of dark adaptation can induce outer retinal thinning and various band intensity changes that can be detected with Optical Coherence Tomography (OCT).

Type II Opsins in the Eye, the Pineal Complex and the Skin of Xenopus laevis: Using Changes in Skin Pigmentation as a Readout of Visual and Circadian Activity

open access: yesFrontiers in Neuroanatomy, 2022
The eye, the pineal complex and the skin are important photosensitive organs. The African clawed frog, Xenopus laevis, senses light from the environment and adjusts skin color accordingly.

Delayed dark adaptation in central serous chorioretinopathy

open access: yesAmerican Journal of Ophthalmology Case Reports, 2021
Purpose: To evaluate the effect of central serous chorioretinopathy (CSCR) on retinal function using dark adaptation in a human subject, and to follow it through resolution of the disease.

Adaptation of social and non-social cues to direction in adults with autism spectrum disorder and neurotypical adults with autistic traits

open access: yesDevelopmental Cognitive Neuroscience, 2018
Perceptual constancy strongly relies on adaptive gain control mechanisms, which shift perception as a function of recent sensory history. Here we examined the extent to which individual differences in magnitude of adaptation aftereffects for social and ...

The effects of smooth pursuit adaptation on the gain of visuomotor transmission in monkeys

open access: yesFrontiers in Systems Neuroscience, 2013
Smooth pursuit eye movements are supported by visual-motor systems, where visual motion information is transformed into eye movement commands. Adaptation of the visuomotor systems for smooth pursuit is an important factor to maintain pursuit accuracy and

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.
