Saccadic inhibition in a guided saccade task [PDF]
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 ...

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.

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

Impaired Initiation But Not Execution of Contralesional Saccades in Hemispatial Neglect [PDF]
Behavioural Neurology, 2002 Patients with unilateral neglect are impaired at making saccades to contralesional targets. Whether this problem arises from a deficit in perception, in planning the saccade or in executing the eye movement or some combination thereof remains unclear. We

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 latency in amblyopia. [PDF]
Journal of Vision, 2016 We measured saccadic latencies in a large sample (total n = 459) of individuals with amblyopia or risk factors for amblyopia, e.g., strabismus or anisometropia, and normal control subjects.

Compensatory saccade in the vestibular impaired monkey
Frontiers in Neurology, 2023 IntroductionLoss of the vestibulo-ocular reflex (VOR) affects visual acuity during head movements. Patients with unilateral and bilateral vestibular deficits often use saccadic eye movements to compensate for an inadequate VOR.

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.

Characteristics of vestibular corrective saccades in patients with slow visual saccades, vestibular disorders and controls: A descriptive analysis. [PDF]
PLoS ONE, 2018 Our aim was to determine whether overt catch up saccades (OS) provoked by vestibular stimuli, as observed in the video head impulse test (vHIT), have comparable metrics as visually triggered horizontal saccades (VS), indicating a common saccadic ...
