Saccadic Adaptation Is Associated with Starting Eye Position [PDF]
Frontiers 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 ...

THE DARK ADAPTATION OF THE HUMAN EYE [PDF]
Journal 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.

Eye Position Specificity of Saccadic Adaptation [PDF]
Investigative Opthalmology & Visual Science, 2003 The accuracy of saccadic eye movements is maintained throughout life by adaptive mechanisms. With the double-step target paradigm, eight human subjects were investigated to determine whether saccadic adaptation depends only on the eye-displacement vector, or also on eye position as a context cue when two saccades of identical vector are adapted ...

Electrophysiological correlates of eye gaze adaptation
Journal of Vision, 2010 Recent research shows a strong effect of adaptation on gaze perception: Adaptation to faces with eye gaze constantly diverted in one direction subsequently impairs the perception of that gaze direction. A previous study on the neural correlates of this effect found that N170 amplitudes to test faces were strongly attenuated following adaptation.

Sensorimotor adaptation of saccadic eye movements
Neuroscience & Biobehavioral Reviews, 2009 Sensory-motor adaptation mechanisms play a pivotal role in maintaining the performance of goal-directed movements. The saccadic system, used to explore the visual environment through fast and accurate shifts of the eyes (saccades), is a valuable model for studying adaptation mechanisms.

Adaptation of Saccadic Eye Movements: Transfer and Specificity [PDF]
Annals of the New York Academy of Sciences, 2003 AbstractThe present study was designed to test whether the adaptation of saccadic eye movements depends only on the eye displacement vector of the trained saccade or also on eye position information. Using the double‐step target paradigm in eight human subjects, we first induced in a single session two “opposite directions adaptations” (ODA) of ...

Frontiers 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.

Suboptimal eye movements for seeing fine details. [PDF]
, 2018 Human eyes are never stable, even during attempts of maintaining gaze on a visual target. Considering transient response characteristics of retinal ganglion cells, a certain amount of motion of the eyes is required to efficiently encode information and ...

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