A sensory memory to preserve visual representations across eye movements

Nature Communications, 2021
A late enhancement of the perisaccadic neural response may exist in extrastriate areas. Here the authors show this preserves pre-saccadic information until the post-saccadic information is received, maintaining an integrated representation of the visual ...

A comparison of post-saccadic oscillations in European-Born and China-Born British University Undergraduates.

PLoS ONE, 2020
Previous research has revealed that people from different genetic, racial, biological, and/or cultural backgrounds may display fundamental differences in eye-tracking behavior. These differences may have a cognitive origin or they may be at a lower level

Saccadic adaptation to moving targets.

PLoS ONE, 2012
Saccades are so called ballistic movements which are executed without online visual feedback. After each saccade the saccadic motor plan is modified in response to post-saccadic feedback with the mechanism of saccadic adaptation.

Adaptive changes to saccade amplitude and target localization do not require pre-saccadic target visibility

Scientific Reports, 2023
The accuracy of saccadic eye movements is maintained by saccadic adaptation, a learning mechanism that is proposed to rely on visual prediction error, i.e., a mismatch between the pre-saccadically predicted and post-saccadically experienced position of ...

Saccades and drifts differentially modulate neuronal activity in V1: Effects of retinal image motion, position, and extraretinal influences [PDF]

, 2008
In natural vision, continuously changing input is generated by fast saccadic eye movements and slow drifts. We analyzed effects of fixational saccades, voluntary saccades, and drifts on the activity of macaque V1 neurons.

Longer fixation duration while viewing face images [PDF]

, 2006
The spatio-temporal properties of saccadic eye movements can be influenced by the cognitive demand and the characteristics of the observed scene. Probably due to its crucial role in social communication, it is argued that face perception may involve ...

The fixation and saccade P3. [PDF]

PLoS ONE, 2012
Although most instances of object recognition during natural viewing occur in the presence of saccades, the neural correlates of objection recognition have almost exclusively been examined during fixation.

Saccade-related activity in the prefrontal cortex: its role in eye movement control and cognitive functions

Frontiers in Integrative Neuroscience, 2014
Prefrontal neurons exhibit saccade-related activity and pre-saccadic memory-related activity often encodes the directions of forthcoming eye movements, in line with demonstrated prefrontal contribution to flexible control of voluntary eye movements ...

Distinct eye movement patterns enhance dynamic visual acuity. [PDF]

PLoS ONE, 2017
Dynamic visual acuity (DVA) is the ability to resolve fine spatial detail in dynamic objects during head fixation, or in static objects during head or body rotation.

Neural Dynamics of Saccadic and Smooth Pursuit Eye Movement Coordination during Visual Tracking of Unpredictably Moving Targets [PDF]

, 2007
How does the brain use eye movements to track objects that move in unpredictable directions and speeds? Saccadic eye movements rapidly foveate peripheral visual or auditory targets and smooth pursuit eye movements keep the fovea pointed toward an ...
