Effect of Saccadic Adaptation on Sequences of Saccades
Journal of Eye Movement Research, 2012 Accuracy of saccadic eye movements is maintained thanks to adaptation mechanisms. The adaptive lengthening and shortening of reactive and voluntary saccades rely on partially separate neural substrates.

Saccades during attempted fixation in parkinsonian disorders and recessive ataxia: from microsaccades to square-wave jerks. [PDF]
PLoS ONE, 2013 During attempted visual fixation, saccades of a range of sizes occur. These "fixational saccades" include microsaccades, which are not apparent in regular clinical tests, and "saccadic intrusions", predominantly horizontal saccades that interrupt ...

Saccadic momentum and facilitation of return saccades contribute to an optimal foraging strategy. [PDF]
PLoS Computational Biology, 2013 The interest in saccadic IOR is funneled by the hypothesis that it serves a clear functional purpose in the selection of fixation points: the facilitation of foraging. In this study, we arrive at a different interpretation of saccadic IOR. First, we find

Saccadic Disinhibition on the Saccade Trace
i-Perception, 2011 It has generally thought that information from the eyes is made available during a fixation, but not during a saccade when reading. Some researchers even suggested the duration of saccades should be subtracted from the reading time in eye movement ...

A Vertical Asymmetry in Saccades
Journal of Eye Movement Research, 2015 Visual exploration of natural scenes imposes demands that differ between the upper and the lower visual hemifield. Yet little is known about how ocular motor performance is affected by the location of visual stimuli or the direction of a behavioural ...

Saccadic suppression in schizophrenia [PDF]
Scientific Reports, 2021 AbstractAbout 40% of schizophrenia patients report discrete visual disturbances which could occur if saccadic suppression, the decrease of visual sensitivity around saccade onset, is impaired. Two mechanisms contribute to saccadic suppression: efference copy processing and backwards masking. Both are reportedly altered in schizophrenia.

Converting Static Image Datasets to Spiking Neuromorphic Datasets Using Saccades [PDF]
Frontiers in Neuroscience, 2015 Creating datasets for Neuromorphic Vision is a challenging task. A lack of available recordings from Neuromorphic Vision sensors means that data must typically be recorded specifically for dataset creation rather than collecting and labeling existing ...

Bayesian identification of fixations, saccades, and smooth pursuits [PDF]
Eye Tracking Research & Application, 2015 Smooth pursuit eye movements provide meaningful insights and information on subject's behavior and health and may, in particular situations, disturb the performance of typical fixation/saccade classification algorithms.

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 ...

Modulation of saccade trajectories during sequential saccades
Journal 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.
