Most objective drowsiness measures have limited ability to provide continuous, accurate
assessment of drowsiness state in operational settings. Spontaneous eye blink parameters …

Resting state functional connectivity (rsFC) evaluated by detecting temporal co-variation of
BOLD signals across multiple brain regions undergoes three major changes following sleep …

Significant inter-individual differences in vigilance decline following sleep deprivation exist.
We characterized functional connectivity in 68 healthy young adult participants in rested …

Fluctuations in resting-state functional connectivity occur but their behavioral significance
remains unclear, largely because correlating behavioral state with dynamic functional …

There are approximately 4,000 fatalities in crashes involving trucks and buses in the United
States each year. Though estimates are wide-ranging, possibly 10 to 20 percent of these …

Sleep deprivation causes physiological alterations (eg, decreased arousal, intrusion of
micro-sleeps), that negatively affect performance on a wide range of cognitive domains …

Being awake means forming new memories, primarily by strengthening neuronal synapses.
The increase in synaptic strength results in increasing neuronal synchronicity, which should …

Remembering the emotions we have experienced in the past is the core of one's unique life-
experience. However, there are many factors, both at the state and trait level that can affect …

Both sleep deprivation and extended task engagement (time-on-task) have been shown to
degrade performance in tasks evaluating sustained attention. Here we used pulsed arterial …

Drowsiness associated with sleep loss and circadian misalignment is a risk factor for
accidents and human error. The percentage of time that the eyes are more than 80% closed …
