The programming of sequences of saccades [PDF]
Experimental Brain Research, 2019 Saccadic eye movements move the high-resolution fovea to point at regions of interest. Saccades can only be generated serially (i.e., one at a time). However, what remains unclear is the extent to which saccades are programmed in parallel (i.e., a series

Saccadic suppression in schizophrenia [PDF]
Scientific Reports, 2021 About 40% of schizophrenia patients report discrete visual disturbances which could occur if saccadic suppression, the decrease of visual sensitivity around saccade onset, is impaired.

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.

Coordination of pupil and saccade responses by the superior colliculus
bioRxiv, 2020 The appearance of a salient stimulus evokes saccadic eye movements and pupil dilation as part of the orienting response. Although the role of the superior colliculus (SC) in saccade and pupil dilation has been established separately, whether and how ...

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

Visual mislocalization during double-step saccades
Frontiers 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 ...

Saccadic inhibition in a guided saccade task
PeerJ, 2018 The eye movement system reacts very systematically to visual transients that are presented during the planning phase of a saccade. About 50 to 70 ms after the onset of a transient, the number of saccades that are started decreases, a phenomenon that has been termed saccadic inhibition.

Geometry of saccades and saccadic cycles
, 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 ...

Biases in the perceived timing of perisaccadic perceptual and motor events [PDF]
, 2006 Subjects typically experience the temporal interval immediately following a saccade as longer than a comparable control interval. One explanation of this effect is that the brain antedates the perceptual onset of a saccade target to around the time of ...
