Thalamic and cortical activities are assumed to be time-locked throughout all vigilance
states. Using simultaneous intracortical and intrathalamic recordings, we demonstrate here …

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 literature on state-dependent fluctuations in thalamocortical activities indicates that in
electrophysiological terms, waking and paradoxical sleep are fundamentally identical states …

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 …

The physiological mechanisms that underlie consciousness and unconsciousness are the
sleep/wake mechanisms. Deep sleep is a state of physiological reversible unconsciousness …

GOTTESMANN, C. The transition from slow-wave sleep to paradoxical sleep: Evolving facts
and concepts of the neurophysiological processes underlying the intermediate stage of …

EEG source localization is an essential tool to reveal the cortical sources underlying brain
oscillatory activity. We applied LORETA, a technique of EEG source localization, to identify …

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

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

Prolonged wakefulness is associated not only with obvious changes in the way we feel and
perform but also with well-known clinical effects, such as increased susceptibility to seizures …
