Effects of aging on BOLD fMRI during prosaccades and antisaccades

, 2006
■ Age affects the ability to inhibit saccadic eye movements. According to current theories, this may be associated with age-induced neurophysiological changes in the brain and with compensatory activation in frontal brain areas. In the present study, the

The Stochastic Early Reaction, Inhibition, and late Action (SERIA) model for antisaccades. [PDF]

PLoS Computational Biology, 2017
The antisaccade task is a classic paradigm used to study the voluntary control of eye movements. It requires participants to suppress a reactive eye movement to a visual target and to concurrently initiate a saccade in the opposite direction.

P01-197 - Prosaccades and Antisaccades in Individuals with ADHD and Autism Using the Gap/overlap Paradigm

, 2010
Saccadic reaction time (SRT), is a good index of visual attention pattern. “Gap/overlap paradigm” is supporting the idea that state of attention (engaged/disengaged) influences the SRT toward stimulus. In “overlap”, fixation point (FP) and target overlap;

Saccadic performance and cortical excitability as trait-markers and state-markers in rapid-cycling bipolar disorder: a 2-case follow-up study.

Frontiers in Psychiatry, 2013
Background: The understanding of physiopathology and cognitive impairments in mood disorders requires finding objective markers. Mood disorders have often been linked to hypometabolism in the prefrontal dorsolateral cortex, and to GABAergic and ...

Inhibitory attentional control in anxiety: Manipulating cognitive load in an antisaccade task. [PDF]

PLoS ONE, 2018
Theorists have proposed that heightened anxiety vulnerability is characterised by reduced attentional control performance and have made the prediction in turn that elevating cognitive load will adversely impact attentional control performance for high ...

Neural Substrates of Attentional Control During Emotional Processing: Evidence From rTMS–fMRI Targeting the Frontal Eye Field

Human Brain Mapping, Volume 47, Issue 7, May 2026.
Using rTMS over the frontal eye field combined with fMRI, we demonstrate that disrupting attentional control slows responses and reduces cortical activity for neutral faces while sparing or amplifying amygdala responses to fearful faces, highlighting a disinhibitory effect of TMS on top‐down control.

Eye movements as predictor of cognitive improvement after cognitive remediation therapy in patients with schizophrenia

Frontiers in Psychiatry
AimBaseline cognitive functions of patients predicted the efficacy of cognitive remediation therapy (CRT), but results are mixed. Eye movement is a more objective and advanced assessment of cognitive functions than neuropsychological testing. We aimed to

Antisaccades generate two types of saccadic inhibition

, 2012
To make an antisaccade away from a stimulus, one must also suppress the more reflexive prosaccade to the stimulus. Whether this inhibition is diffuse or specific for saccade direction is not known.

Age-related Saccadic Reaction Time Associated with Attention and Working Memory

Neurological Sciences and Neurophysiology
Objective: This study examined saccadic reaction time (SRT) in visually guided saccades according to age and its relationship with attention and working memory. Materials and Methods: The study participants were divided into three groups: young adulthood
