Effects of Different Numbers of Trials on Saccadometry Test Results [PDF]
Brain and BehaviorPurpose The aim of this study was to investigate the effect of the number of trials on the recording in the saccadometry test. Method Forty‐five healthy participants (mean age ± SD = 25.89 ± 5.2 years) (31 female and 14 male) aged 19–40 years were ...

Response suppression delays the planning of subsequent stimulus-driven saccades. [PDF]
PLoS ONE, 2014 The completion of an antisaccade selectively increases the reaction tiME (RT) of a subsequent prosaccade: a result that has been interpreted to reflect the residual inhibition of stimulus-driven saccade networks [1], [2].

Systematic diagonal and vertical errors in antisaccades and memory-guided saccades [PDF]
Journal of Eye Movement Research, 2010 Studies of memory-guided saccades in monkeys show an upward bias, while studies of antisaccades in humans show a diagonal effect, a deviation of endpoints toward the 45° diagonal.

Increased attentional focus modulates eye movements in a mixed antisaccade task for younger and older adults. [PDF]
PLoS ONE, 2013 We examined performance in the antisaccade task for younger and older adults by comparing latencies and errors in what we defined as high attentional focus (mixed antisaccades and prosaccades in the same block) and low attentional focus (antisaccades and

A Vertical Asymmetry in Saccades [PDF]
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 ...

Multimodal oculomotor assessment reveals prodromal markers of Parkinson’s disease in non-manifesting LRRK2 G2019S mutation carriers [PDF]
npj Parkinson's DiseaseOculomotor behaviour changes in patients with Parkinson’s disease (PD) are a promising source of prodromal disease markers. Capitalizing on this phenomenon to facilitate early diagnosis requires oculomotor assessment in prodromal cohorts.

Oculomotor Dysfunction in Idiopathic and -Parkinson’s Disease and At-Risk Individuals [PDF]
Journal of Parkinson’s DiseaseBackground: Video-oculography constitutes a highly-sensitive method of characterizing ocular movements, which could detect subtle premotor changes and contribute to the early diagnosis of Parkinson’s disease (PD).

Effects of deep brain stimulation frequency on eye movements and cognitive control [PDF]
npj Parkinson's Disease, 2023 Deep brain stimulation (DBS) of the subthalamic nucleus (STN) is an effective treatment for Parkinson’s disease (PD). Varying the frequency DBS has differential effects on axial and distal limb functions, suggesting differing modulation of relevant ...

Acute stress imparts a transient benefit to task-switching that is not modulated following a single bout of exercise [PDF]
Frontiers in Psychology, 2023 IntroductionCognitive flexibility represents a core component of executive function that promotes the ability to efficiently alternate—or “switch”—between different tasks.

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 ...
