Acute Effects of Different Exercise Intensities on Executive Function and Oculomotor Performance in Middle-Aged and Older Adults: Moderate-Intensity Continuous Exercise vs. High-Intensity Interval Exercise

Frontiers in Aging Neuroscience, 2021
A wealth of evidence has shown that a single bout of aerobic exercise can facilitate executive function. However, none of current studies on this topic have addressed whether the magnitude of the acute-exercise benefit on executive function and ...

Effects of Different Numbers of Trials on Saccadometry Test Results. [PDF]

Brain Behav
This study found that increasing the number of trials in the saccadometry test significantly impaired antisaccade performance by increasing latency and error rates, while prosaccade results remained stable. The findings highlight the importance of optimizing trial numbers in antisaccade testing for accurate assessment of eye movement control.

Ocular Motor Abnormalities in Functional Neurological Disorder: A Video-Oculography Study. [PDF]

Mov Disord Clin Pract
Abstract Background Functional neurological disorders (FND) can include various sensory, motor or cognitive symptoms. Eye movement recordings, measured through video‐oculography, could serve as biomarkers for characterizing these dysfunctions in FND.

The Impact of Bulbar and Upper Motor Neuron Involvement on Oculomotor Movement in Amyotrophic Lateral Sclerosis. [PDF]

Brain Behav
Oculomotor assessment revealed that ALS patients, especially those with bulbar or upper motor neuron (UMN) involvement, showed slower anti‐saccade reaction times and lower predictive saccade accuracy than healthy controls. These findings suggest distinct patterns of oculomotor dysfunction among ALS subgroups, highlighting the value of these metrics for

Exogenous capture accounts for fundamental differences between prosaccade and antisaccade performance

bioRxiv, 2022
Oculomotor circuits generate eye movements based on the physical salience of objects and current behavioral goals, exogenous and endogenous influences, respectively.

Affective Modulation of Preparatory Cognitive Activity. [PDF]

Psych J
ABSTRACT This EEG and eye‐tracking study investigated affective influences on cognitive preparation using a precued pro−/antisaccade task with emotional faces as cues. Negative information interfered with preparatory processes with high but not low executive function load.

A Single Bout of Intermittent Hypoxia Increases Cerebral Blood Flow and Supports an Executive Function Benefit. [PDF]

Psychophysiology
ABSTRACT Alternating between brief normoxic and hypoxic intervals (i.e., intermittent hypoxia: IH) increases cerebrovascular dilation, cerebral blood flow (CBF), and O2 extraction. Some work has shown that the physiological adaptations arising from multiple IH sessions improve brain health and executive function (EF)—a finding linked to a post ...

Acute stress imparts a transient benefit to task-switching that is not modulated following a single bout of exercise

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.
