Association of saccade duration and saccade acceleration/deceleration asymmetry during visually guided saccade in schizophrenia patients. [PDF]

open access: yesPLoS ONE, 2014
OBJECTIVE: To examine the difference between schizophrenia patients and normal controls on velocity and acceleration of saccade, by using the basic visually guided saccade (VGS) paradigm.

Effort drives saccade selection

open access: yeseLife
What determines where to move the eyes? We recently showed that pupil size, a well-established marker of effort, also reflects the effort associated with making a saccade (‘saccade costs’).

Mechanisms of saccade suppression revealed in the anti-saccade task [PDF]

open access: yesPhilosophical Transactions of the Royal Society B: Biological Sciences, 2017
The anti-saccade task has emerged as an important tool for investigating the complex nature of voluntary behaviour. In this task, participants are instructed to suppress the natural response to look at a peripheral visual stimulus and look in the opposite direction instead.

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 ...

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 ...
