Vigilant attention is a major component of a wide range of cognitive performance tasks.
Vigilant attention is impaired by sleep deprivation and restored after rest breaks and (more …

Sleep function remains controversial. Individual perspectives frame the issue of sleep
function differently. We briefly illustrate how sleep measurement and the evolution, tissue …

Fatigue–a feeling of exhaustion arising from exertion–is a significant barrier to successful
behaviour and one of the most prominent symptoms in primary care. During extended …

Abstract Study Objectives: Attention is a cognitive domain that can be severely affected by
sleep deprivation. Previous neuroimaging studies have used different attention paradigms …

Sleep deprivation (SD) consistently degrades performance in tasks requiring sustained
attention, resulting in slower and more variable response times that worsen with time-on …

Stable trait-like responding is well established for neurobehavioral performance measures
across repeated exposures to total sleep deprivation and partial chronic sleep restriction …

Elucidating the neurobiological effects of sleep and wake is an important goal of the
neurosciences. Whether and how human cerebral blood flow (CBF) changes during the …

The present study mainly aimed to assess whether and how sleepiness due to sleep
deprivation interacts with Time on Task (ToT) effects both on electroencephalography (EEG) …

The effects of sleep deprivation (SD) on the neural substrates of inhibition control are poorly
understood. Here we used functional magnetic resonance imaging to examine the effects of …

After continuous and prolonged cognitive workload, people typically show reduced
behavioral performance and increased feelings of fatigue, which are known as “time-on-task …
