The futuristic manifolds of REM sleep

Journal of Sleep Research, Volume 34, Issue 2, April 2025.
Summary Since one of its first descriptions 70 years ago, rapid eye movement sleep has continually inspired and excited new generations of sleep researchers. Despite significant advancements in understanding its neurocircuitry, underlying mechanisms and microstates, many questions regarding its function, especially beyond the early neurodevelopment ...

Music cue during slow wave sleep improves visuospatial memory consolidation

Journal of Sleep Research, Volume 34, Issue 3, June 2025.
Summary The active system consolidation theory assumes that sleep between encoding and retrieval promotes memory consolidation. In the present study, we cued new memories during slow‐wave (SWS) or rapid eye movements (REM) sleep stages by presenting an instrumental music stimuli that had been previously presented during a learning session.

No effect of napping on episodic foresight and prospective memory in kindergarten children

Journal of Sleep Research, Volume 34, Issue 3, June 2025.
Summary Preschool children often have problems in remembering to carry out a planned behaviour. This study investigated the impact of napping on episodic foresight (planning for future events) and prospective memory (remembering to perform an action in the future) in 2–3‐year‐old children. In a quasi‐experimental design, we compared children who napped

Self‐care behaviours in patients with restless legs syndrome (RLS): development and psychometric testing of the RLS‐Self‐care Behaviour questionnaire

Journal of Sleep Research, Volume 34, Issue 3, June 2025.
Summary Restless legs syndrome (RLS) is a highly prevalent condition that significantly disrupts sleep and causes reduced quality of life. While previous RLS research has mainly focused on the pharmacological treatment, this study presents the first instrument to measure self‐care, the RLS‐Self‐care Behaviour questionnaire (RLS‐ScBq).

An afternoon nap facilitates analogical transfer in creative problem solving

Journal of Sleep Research, EarlyView.
Summary In analogical problem solving, the solution to a previously experienced problem (source) is used to solve a new but structurally similar problem (target). Yet, analogical transfer is seldom successful, as structural commonalities between source and target problems can be difficult to recognise.

Promoting vocabulary learning during sleep at home using closed‐loop targeted memory reactivation

Journal of Sleep Research, EarlyView.
Summary Targeted memory reactivation represents an established technique for promoting sleep‐dependent memory consolidation in laboratory studies. This investigation aimed to test the potentiality of a wearable electroencephalography‐based closed‐loop targeted memory reactivation system to boost vocabulary learning in home settings.

The cathartic dream: Using a large language model to study a new type of functional dream in healthy and clinical populations

Journal of Sleep Research, EarlyView.
Summary According to some theories of emotion regulation, dreams could modify negative emotions and ultimately reduce their intensity. We introduce here the idea of cathartic dream, a specific and separate type of emotional dream, which is characterized by a dynamic plot with emotional twists, and where negative emotions are expressed and ultimately ...

The influence of sleep disruption on learning and memory in fish

Journal of Sleep Research, EarlyView.
Summary Sleep is a ubiquitous process that has been conserved in animals. Yet, our understanding of the functions of sleep largely derives from a few species. Sleep is considered to play an important role in mental processes, including learning and memory consolidation, but how widespread this relationship is across taxa remains unclear.

NREM Sleep Oscillations Are Associated With Anxiety and Negative Affect in Young Adults

Journal of Sleep Research, EarlyView.
ABSTRACT Non‐rapid eye movement sleep (NREM) oscillations are critical for cognitive and affective processing. While several studies link anxiety and depression symptoms to sleep quality, a critical gap remains in elucidating the role of NREM physiology in sleep‐dependent processing of affect and anxiety symptoms. The goals of the present study were to

The Space–Time Organisation of Sleep Slow Oscillations as Potential Biomarker for Hypersomnolence

Journal of Sleep Research, EarlyView.
ABSTRACT Research suggests that the spatial profile of slow wave activity (SWA) could be altered in hypersomnolence. Slow oscillations (SOs; 0.5–1.5 Hz), single waveform events contributing to SWA, can be labelled as Global, Frontal, or Local depending on their presentation on the scalp.
