Saccadometry Findings in Migraine Patients Without Aura [PDF]

Brain and Behavior
Including Migraine without aura is a common neurological disorder associated with structural and functional changes in the brain, which may lead to impairments in cognitive control and motor function.

Conflicting Motor Plans and Sensory Attenuation: Evidence From Event-Related Potentials for Sounds Generated by Pro- and Antisaccades. [PDF]

Psychophysiology
The reduction of neural responses to self‐ versus externally generated stimuli has been ascribed to predictions based on an efference copy of motor commands. However, general predictive mechanisms not specific to movements may also play a role.

The unidirectional prosaccade switch-cost: Correct and error antisaccades differentially influence the planning times for subsequent prosaccades [PDF]

Vision Research, 2014
Antisaccades produce longer reaction times (RT) than their prosaccade counterparts and this latency increase has been linked to an oculomotor ‘pre-setting’ that prevents the evocation of a stimulus-driven prosaccade. Moreover, a consequence of oculomotor

Oculomotor atypicalities in motor neurone disease: a systematic review [PDF]

Frontiers in Neuroscience
IntroductionCognitive dysfunction is commonplace in Motor Neurone Disease (MND). However, due to the prominent motor symptoms in MND, assessing patients’ cognitive function through traditional cognitive assessments, which oftentimes require motoric ...

Mixed saccadic paradigm releases top-down emotional interference in antisaccade and prosaccade trials

Experimental Brain Research, 2016
Saccadic movements are well known to involve specific top-down or bottom-up processes depending on the task and paradigm characteristics. For example, after the Gap bottom-up effect, it has been shown that an Instruction effect, i.e., asking to identify ...

Coupling of saccade plans to endogenous attention during urgent choices [PDF]

eLife
The neural mechanisms that willfully direct attention to specific locations in space are closely related to those for generating targeting eye movements (saccades).

Abnormal eye movements: relationship with clinical symptoms and predictive value for Alzheimer's disease. [PDF]

Front Aging Neurosci
Background Abnormal eye movements occur at the early stages of Alzheimer’s disease (AD). However, the characteristics of abnormal eye movements of patients with AD and their relationship with clinical symptoms remain inconsistent, and their predictive ...

Instability of Oculomotor Control in Parkinson's Disease Without Freezing of Gait: Evidence From Reflexive and Voluntary Saccade Variability. [PDF]

Eur J Neurosci
This study found that people with Parkinson's disease without freezing of gait show higher error rate and peak velocity to amplitude ratio during prosaccade task compared to controls. Also, Parkinson patients show more variation in gain, peak velocity, peak acceleration and peak velocity to amplitude ratio compared to control group.

Convergence Deficits in Myoclonus-Dystonia Point to Cerebellar Impairment. [PDF]

Mov Disord Clin Pract
Abstract Background Myoclonus‐dystonia (M‐D) is a monogenic movement disorder, with proposed cerebellar dysfunction. Vergence eye movement deficits, characteristics of degenerative cerebellar disease, have not been studied in M‐D. Cerebellar transcranial alternating current stimulation (tACS) is considered a potential therapeutic approach.

Effect of habitual reading direction on saccadic eye movements: A pilot study.

PLoS ONE, 2023
Cognitive processes can influence the characteristics of saccadic eye movements. Reading habits, including habitual reading direction, also affect cognitive and visuospatial processes, favouring attention to the side where reading begins.
