REM sleep favors the restructuring of problem-related semantic associations Open
REM sleep is considered a ‘hyperassociative’ state enhancing the connections between weakly related concepts, thereby facilitating memory restructuring — a critical process proposed in creative problem-solving. Here, we empirically explore…
Light propofol anaesthesia for non-invasive auditory EEG recording in unrestrained non-human primates Open
Non-invasive electroencephalographic (EEG) experiments have been instrumental in advancing our understanding of the brain mechanisms involved in the production and perception of sounds and human speech. Performing similar experiments in no…
Embracing sleep onset complexity Open
Sleep is crucial for many vital functions and is extensively studied. In contrast, the sleep onset period, often portrayed as a mere prelude to sleep, has been largely overlooked and remains poorly characterised. However, a recent series o…

DREAM: A Dream EEG and Mentation database Open
Magneto/electroencephalography (M/EEG) studies of dreaming are an essential paradigm in the investigation of neurocognitive processes of human consciousness during sleep, but they are limited by the number of observations that can be colle…

Memory loss at sleep onset Open
Every night, we pass through a transitory zone at the borderland between wakefulness and sleep, named the first stage of nonrapid eye movement sleep (N1). N1 sleep is associated with increased hippocampal activity and dream-like experience…

Sleep onset is a creative sweet spot Open
A single minute of sleep onset is sufficient to boost the probability of insight by a factor of three compared to wake.
The borderland between wakefulness and sleep, a doorway into creativity Open
Each night, we cross a bridge that connects the waking and sleeping worlds. We know very little about this bridge (symbolizing the sleep-onset period), as our passage is brief and leaves only a few fragmented memories behind. Moreover, sle…
Dynamic changes in semantic memory structure support successful problem-solving Open
Creative problem-solving is central in daily life, yet its underlying mechanisms remain elusive. Restructuring (i.e., reorganization of problem-related representations) is considered one problem-solving mechanism and may lead to an abstrac…
Sleepers Selectively Suppress Informative Inputs during Rapid Eye Movements Open
Sleep leads to a disconnection from the external world. Even when sleepers regain consciousness during rapid eye movement (REM) sleep, little, if any, external information is incorporated into dream content [1-3]. While gating mechanisms m…
Increased creative thinking in narcolepsy Open
Some studies suggest a link between creativity and rapid eye movement sleep. Narcolepsy is characterized by falling asleep directly into rapid eye movement sleep, states of dissociated wakefulness and rapid eye movement sleep (cataplexy, h…
Increased creative thinking in narcolepsy Open
These are the data that support the findings of the study "Increased creative thinking in narcolepsy".
