Lapses of attention manifest as delayed behavioral responses to salient stimuli. Although
they can occur even after a normal night's sleep, they are longer in duration and more …

Humans are less responsive to the surrounding environment during sleep. However, the
extent to which the human brain responds to external stimuli during sleep is uncertain. We …

Sleep deprivation impairs alertness and cognitive performance, and these deficits suggest
decreases in brain activity and function, particularly in the prefrontal cortex, a region …

The neuronal connectivity patterns that differentiate consciousness from unconsciousness
remain unclear. Previous studies have demonstrated that effective connectivity, as assessed …

The study of sleep and dreams has enjoyed a major breakthrough with recent findings from
brain imaging studies in humans. Several independent groups have shown global …

Human sleep is considered a global phenomenon, orchestrated by central specialized
neuronal networks modulating the whole-brain activity. However, recent studies point to a …

Spontaneous and sensory-evoked cortical activity is highly state-dependent, yet relatively
little is known about transitions between distinct waking states. Patterns of activity in mouse …

This unique and up-to-date book provides a comprehensive history and critical account of
sleep mentation research since the introduction of electrographic techniques. Written by …

Cognitive hyperarousal, resulting in enhanced cognitive activation, has been cited as an
important contributor to the development and preservation of insomnia. To further …

Abstract Study Objectives: To determine whether thalamocortical signaling between the
thalamus and the neocortex decreases from wakefulness to nonrapid eye movement …
