Abnormal Eye Movements in Parkinsonism and Movement Disorders [PDF]

open access: yesJournal of Movement Disorders, 2019
Abnormal eye movements are commonly observed in movement disorders. Ocular motility examination should include bedside evaluation and laboratory recording of ocular misalignment, involuntary eye movements, including nystagmus and saccadic intrusions ...

Spatial frequency processing in the central and peripheral visual field during scene viewing

open access: yes, 2016
Visuospatial attention and gaze control depend on the interaction of foveal and peripheral processing. The foveal and peripheral regions of the visual field are differentially sensitive to parts of the spatial-frequency spectrum.

Saccades and microsaccades during visual fixation, exploration, and search: foundations for a common saccadic generator.

open access: yesJournal of Vision, 2008
Microsaccades are known to occur during prolonged visual fixation, but it is a matter of controversy whether they also happen during free-viewing. Here we set out to determine: 1) whether microsaccades occur during free visual exploration and visual ...

Saccade learning with concurrent cortical and subcortical basal ganglia loops [PDF]

open access: yes, 2013
The Basal Ganglia is a central structure involved in multiple cortical and subcortical loops. Some of these loops are believed to be responsible for saccade target selection.

Influence of retinal image shifts and extra-retinal eye movement signals on binocular rivalry alternations. [PDF]

open access: yesPLoS ONE, 2013
Previous studies have indicated that saccadic eye movements correlate positively with perceptual alternations in binocular rivalry, presumably because the foveal image changes resulting from saccades, rather than the eye movement themselves, cause ...

Paroxysmal eye–head movements in Glut1 deficiency syndrome [PDF]

open access: yes, 2017
Objective:To describe a characteristic paroxysmal eye–head movement disorder that occurs in infants with Glut1 deficiency syndrome (Glut1 DS).Methods:We retrospectively reviewed the medical charts of 101 patients with Glut1 DS to obtain clinical data ...

Unmasking saccadic uncrowding

open access: yesVision Research, 2016
Stimuli that are briefly presented around the time of saccades are often perceived with spatiotemporal distortions. These distortions do not always have deleterious effects on the visibility and identification of a stimulus. Recent studies reported that when a stimulus is the target of an intended saccade, it is released from both masking and crowding.

Looking away from faces: influence of high-level visual processes on saccade programming

open access: yes, 2010
Human faces capture attention more than other visual stimuli. Here we investigated whether such face-specific biases rely on automatic (involuntary) or voluntary orienting responses.

Saccades in children

open access: yesVision Research, 2006
Saccades are necessary for optimal vision. Little is known about saccades in children. We recorded saccades using an infrared eye tracker in 39 children, aged 8-19 years. Participants made saccades to visual targets that stepped 10 degrees or 15 degrees horizontally and 5 degrees or 10 degrees vertically at unpredictable time intervals.
