Characteristics of saccadic intrusions

Vision Research, 2004
Primary fixation is never perfectly stable, but is frequently interrupted by slow drifts, microsaccades and saccadic intrusions (SI). SI are involuntary, conjugate movements which take the form of an initial fast movement away from the desired eye position and followed after a short duration, by either a return secondary saccade or a drift. The purpose

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 of such moments can be planned together) and how far ahead such planning occurs.

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

Journal 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 ...

The Concurrent Programming of Saccades [PDF]

PLOS 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 saccade; a voluntary saccade; a reflexive then a voluntary saccade; or vice versa. During the first

Shapes, surfaces and saccades

Vision Research, 1999
Saccadic localization of spatially extended objects requires the computation of a single saccadic landing position. What representation of the target guides saccades? Saccades were examined for various targets composed of dots to determine whether landing position corresponded to the center-of-gravity (average location) of the dots, the center-of-area ...

The Spectrum of Neurologic Phenotypes Associated With NUS1 Pathogenic Variants: A Comprehensive Case Series

Annals of Neurology, EarlyView.
Objective A growing body of evidence indicates a strong genetic overlap between developmental and epileptic encephalopathies (DEEs) and movement disorders. De novo loss‐of‐function variants in NUS1 have been recently identified in DEE cases. Herein, we report a large cohort of cases with pathogenic NUS1 variants and describe their clinical presentation

Different effects of double-pulse TMS of the posterior parietal cortex on reflexive and voluntary saccades

Frontiers in Human Neuroscience, 2011
Gap and overlap tasks are widely used to promote automatic versus controlled saccades. This study examines the hypothesis that the right posterior parietal cortex (PPC) is differently involved in the two tasks. Twelve healthy students participated in the
