[HTML][HTML] Consciousness and cortical responsiveness: a within-state study during non-rapid eye movement sleep
When subjects become unconscious, there is a characteristic change in the way the cerebral
cortex responds to perturbations, as can be assessed using transcranial magnetic …

[HTML][HTML] Evoked alpha power is reduced in disconnected consciousness during sleep and anesthesia
M Darracq, CM Funk, D Polyakov, B Riedner… - Scientific reports, 2018 - nature.com
Sleep and anesthesia entail alterations in conscious experience. Conscious experience
may be absent (unconsciousness) or take the form of dreaming, a state in which sensory …

[HTML][HTML] Connectivity differences between consciousness and unconsciousness in non-rapid eye movement sleep: a TMS–EEG study
The neuronal connectivity patterns that differentiate consciousness from unconsciousness
remain unclear. Previous studies have demonstrated that effective connectivity, as assessed …

Human cortical excitability increases with time awake
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 …

A Pigorini, S Sarasso, P Proserpio, C Szymanski… - Neuroimage, 2015 - Elsevier
During non-rapid eye movement (NREM) sleep (stage N3), when consciousness fades,
cortico-cortical interactions are impaired while neurons are still active and reactive. Why is …

Why does consciousness fade in early sleep?
G Tononi, M Massimini - Annals of the New York Academy of …, 2008 - Wiley Online Library
Consciousness fades during deep nonrapid eye movement (NREM) sleep early in the night,
yet cortical neurons remain active, keep receiving sensory inputs, and can display patterns …

The neural correlates of dreaming
Consciousness never fades during waking. However, when awakened from sleep, we
sometimes recall dreams and sometimes recall no experiences. Traditionally, dreaming has …

Sleep and consciousness
Sleep offers a unique opportunity to relate changes in brain activity to changes in
consciousness. Indeed, if it were not for sleep, when consciousness fades in and out on a …
