The Concurrent Programming of Saccades. [PDF]

open access: yesPLoS ONE, 2016
Sequences of saccades have been shown to be prepared concurrently however it remains unclear exactly what aspects of those saccades are programmed in parallel. To examine this participants were asked to make one or two target-driven saccades: a reflexive

Horizontal saccade bias results from combination of saliency anisotropies and egocentric biases [PDF]

open access: yesScientific Reports
Saccadic eye movements shift the fovea between objects of interest to build a visual percept. In humans, saccades are predominantly executed along the cardinal axes, particularly in the horizontal direction. It is unknown how this horizontal saccade bias

Investigating Arousal, Saccade Preparation, and Global Luminance Effects on Microsaccade Behavior

open access: yesFrontiers in Human Neuroscience, 2021
Microsaccades, small saccadic eye movements occurring during fixation, have been suggested to be modulated by various sensory, cognitive, and affective processes relating to arousal.

Is mislocalization during saccades related to the position of the saccade target within the image or to the gaze position at the end of the saccade? [PDF]

open access: yesPLoS ONE, 2013
A stimulus that is flashed around the time of a saccade tends to be mislocalized in the direction of the saccade target. Our question is whether the mislocalization is related to the position of the saccade target within the image or to the gaze position

Geometry of Saccades and Saccadic Cycles

open access: yes, 2023
The paper is devoted to the development of the differential geometry of saccades and saccadic cycles. We recall an interpretation of Donder's and Listing's law in terms of the Hopf fibration of the $3$-sphere over the $2$-sphere. In particular, the configuration space of the eye ball (when the head is fixed) is the 2-dimensional hemisphere $S^+_L ...

Pre-saccadic perception: Separate time courses for enhancement and spatial pooling at the saccade target. [PDF]

open access: yesPLoS ONE, 2017
We interact with complex scenes using eye movements to select targets of interest. Studies have shown that the future target of a saccadic eye movement is processed differently by the visual system.

Dissociable roles of human frontal eye fields and early visual cortex in presaccadic attention

open access: yesNature Communications, 2023
Shortly before saccadic eye movements, visual sensitivity at the saccade target is enhanced, at the expense of sensitivity elsewhere. Some behavioral and neural correlates of this presaccadic shift of attention resemble those of covert attention ...

Visual mislocalization during double-step saccades

open access: yesFrontiers in Systems Neuroscience, 2015
Visual objects presented briefly at the time of saccade onset appear compressed toward the saccade target. Compression strength depends on the presentation of a visual saccade target signal and is strongly reduced during the second saccade of a double ...

Modulation of saccade trajectories during sequential saccades

open access: yesJournal of Neurophysiology, 2021
We show that in saccade sequences, saccade trajectory is modulated in the direction of the preceding saccade and away from the following saccade. The magnitude of this effect is correlated with preceding and following saccade amplitude. This confirms that programming of sequential saccades overlaps.

Regularities in vertical saccadic metrics: new insights, and future perspectives

open access: yesFrontiers in Psychology, 2023
IntroductionAsymmetries in processing by the healthy brain demonstrate regularities that facilitate the modeling of brain operations. The goal of the present study was to determine asymmetries in saccadic metrics during visual exploration, devoid of ...
