Consciousness is reduced during nonrapid eye movement (NREM) sleep due to changes in
brain function that are still poorly understood. Here, we tested the hypothesis that impaired …

Consciousness is often said to disappear in deep, dreamless sleep. We argue that this
assumption is oversimplified. Unless dreamless sleep is defined as unconscious from the …

Despite increasing scientific interest in self‐generated thought—mental content largely
independent of the immediate environment—there has yet to be any comprehensive …

This metatheoretical paper develops a list of new research targets by exploring particularly
promising interdisciplinary contact points between empirical dream research and philosophy …

Consciousness transiently fades away during deep sleep, more stably under anesthesia,
and sometimes permanently due to brain injury. The development of an index to quantify the …

Several studies have tried to identify the neurobiological bases of dream experiences,
nevertheless some questions are still at the centre of the debate. Here, we summarise the …

From Biblical stories of Joseph interpreting Pharoh's dreams in Egypt to prayers against bad
dreams in the Hindu Rg Veda, cultures all over the world have seen their dreams first and …

Sleep, like breathing, is a biologic rhythm that is actively generated by the brain. Neuronal
networks that have evolved to regulate naturally occurring sleep preferentially modulate …

Our basic thesis is that depression is an evolutionarily conserved mechanism in mammalian
brains, selected as a shutdown mechanism to terminate protracted separation distress (a …

High thalamocortical neuronal activity characterizes both, wakefulness and rapid eye
movement (REM) sleep, but apparently this network fulfills other roles than processing …
