Correlation of the Karolinska Sleepiness with Behavioral Measures of a Monotonous Bimanual Psychomotor Rest
Objectives . To assess the objectivity of measurements of the level of drowsiness in subjects using a previously developed monotonous psychomotor...

One night of 10-h sleep restores vigilance after total sleep deprivation: the role of delta and theta power during recovery sleep
A series of studies have demonstrated that impaired vigilance performance caused by total sleep deprivation could restore to baseline when recovery...

Long-range and cross-frequency neural modulation of gamma flicker on vigilance decrement
Vigilance decrement is a ubiquitous problem in attention-demanding tasks. Therefore, it is significant to develop neuromodulation methods to mitigate...
-
Differences in brain activity between fast and slow responses on psychomotor vigilance task: an fNIRS study
Attention is a basic human function underlying every other cognitive process. It is demonstrated in the functional Magnetic Resonance Imaging...

Interhemispheric Asymmetry of Connections of EEG Rhythms on Spontaneous Waking after Transient Episodes of Sleep while Performing a Monotonous Psychomotor Test
Objectives . To study interhemispheric asymmetry (IHA) by electroencephalography (EEG) in healthy subjects during cognitive waking from stage II...
-
Isolation of subjectively reported sleepiness and objectively measured vigilance during sleep deprivation: a resting-state fMRI study
Subjectively reported sleepiness and objectively measured vigilance are often used to assess and monitor operating performance. Evidence suggests...

EEG Characteristics and Anxiety Levels in Subjects with Different Levels of Success in Recovering Psychomotor Activity on Waking During Daytime Sleep
Studies in healthy adult volunteers with different levels of anxiety addressed the effectiveness of recovery of monotonous activity after brief...

Effects of alcohol intoxication on driving performance, confidence in driving ability, and psychomotor function: a randomized, double-blind, placebo-controlled study
RationaleAlcohol-induced driving impairment can occur with any departure from a zero-blood alcohol concentration (BAC). Because intoxication is...

Ambient-task combined lighting to regulate autonomic and psychomotor arousal levels without compromising subjective comfort to lighting
BackgroundAlthough evidence of both beneficial and adverse biological effects of lighting has accumulated, biologically favorable lighting often does...

A single bout of passive exercise mitigates a mental fatigue-induced inhibitory control deficit
Sustained cognitive effort associated with the psychomotor vigilance task (PVT) increases objective and subjective measures of mental fatigue and...
-
Effects of fatigue on attention and vigilance as measured with a modified attention network test
As part of a larger study on the effects of fatigue on various attentional and behavioural measures, we had participants complete a modified version...
-
Prefrontal cortex oxygenation during a mentally fatiguing task in normoxia and hypoxia
Mental fatigue (MF) and hypoxia impair cognitive performance through changes in brain hemodynamics. We want to elucidate the role of prefrontal...
-
Assessing the impact of sleep restriction on the attention and executive functions of medical students: a prospective cohort study
ObjectiveTo compare the performance of medical students regarding attention and executive functions during a period of sleep restriction...

Evaluating possible ‘next day’ impairment in insomnia patients administered an oral medicinal cannabis product by night: a pilot randomized controlled trial
Cannabis and its major constituents, Δ 9 -tetrahydrocannabinol (THC) and cannabidiol (CBD), are being widely used to treat sleep disturbances. However,...

Chronic, acute and protocol-dependent effects of exercise on psycho-physiological health during long-term isolation and confinement
Exercise could prevent physical and psychological deteriorations, especially during pandemic times of lock-down scenarios and social isolation. But...

Dietary nitrate supplementation enhances heavy load carriage performance in military cadets
PurposeTo determine the effects of dietary nitrate (NO 3 − ) supplementation on physiological responses, cognitive function, and performance during...
-
The cortical oscillatory patterns associated with varying levels of reward during an effortful vigilance task
We explored how reward and value of effort shapes performance in a sustained vigilance, reaction time (RT) task. It was posited that reward and value...

Traffic Safety in Sleep Deprivation, Sleepiness, and Sleep Disorders
Every year, a substantial number of people are killed or injured due to motor vehicle accidents (MVAs). A large number of these collisions are caused...
