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 ...

Network Adaptation Improves Temporal Representation of Naturalistic Stimuli in Drosophila Eye: II Mechanisms [PDF]
, 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.

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.

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 saccades at other locations.

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 ...

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.

A local model of eye adaptation for high dynamic range images [PDF]
, 2004 In the real world, the human eye is confronted with a wide range of luminances from bright sunshine to low night light. Our eyes cope with this vast range of intensities by adaptation; changing their sensitivity to be responsive at di erent ...
