Article
Increasingly studied in a systematic manner since the 1970s, the cognitive processes of the brain taking place during sleeping periods remain an important object of scrutiny in the scientific community. In particular, sleep has been demonstrated to play a significant role for learning and memory consolidation processes, and sleep scientists have st...

Previously, we demonstrated that precise temporal coordination between slow oscillations (SOs) and sleep spindles indexes declarative memory network development (Hahn et al., 2020). However, it is unclear whether these findings in the declarative memory domain also apply in the motor memory domain. Here, we compared adolescents and adults learning...
Preprint
Understanding the complex relationship between sleep and memory is a major challenge in neuroscience. Thousands of studies on memory consolidation in humans suggest that sleep triggers offline memory processes, resulting in less forgetting of declarative memory and performance stabilization in non-declarative memory. However, an increasing number o...

Smartphone usage strongly increased in the last decade, especially before bedtime. There is growing evidence that short-wavelength light affects hormonal secretion, thermoregulation, sleep and alertness. Whether blue light filters can attenuate these negative effects is still not clear. Therefore, here, we present preliminary data of 14 male partic...

Internalizing problems are characterized by deficits in emotion processing and regulation. They are among the most common problems in children and adolescents and mark an increased risk for depressive and anxiety disorders in later life. First evidence suggests that sleep alterations are related to the development and/or persistence of mood and anx...

Precise temporal coordination between slow oscillations (SO) and sleep spindles indexes declarative memory network development. SO-spindle interplay is thought to time subcortical-cortical network communication. However, it is currently unclear whether these findings in the declarative memory domain also apply in the motor memory domain. Here, we c...

Sleep spindles benefit declarative memory consolidation and are considered to be a biological marker for general cognitive abilities. However, the impact of sexual hormones and hormonal oral contraceptives (OCs) on these relationships are less clear. Thus, we here investigated the influence of endogenous progesterone levels of naturally cycling wom...

Exposure to short-wavelength light during the evening increases alertness and suppresses melatonin secretion. Negative effects on sleep onset latency, sleep fragmentation, early slow wave activity and slow wave sleep have been reported previously. However, it is unclear whether these effects of short-wavelength light can affect overnight memory con...

Electronic media (e.g., smartphones) are increasingly used among adolescents and young adults, especially in the evening and during bedtime. Smartphones are equipped with LED-screens, which emit a considerable amount of short-wavelength-light. Evidence from previous studies showed influences of evening short-wavelength-light exposure on the circadi...

Research unravelling the facilitating role of sleep for cognitive processes is nowadays mainly performed in adults. Neural activity patterns during NREM sleep like sleep spindles and slow oscillations have been shown to guide and time the reactivation, transformation and stabilization of memories. Whether and how sleep — especially sleep spindles —...

Sleep has been shown to facilitate the consolidation of newly acquired motor memories. However, the role of sleep in gross motor learning, especially in motor adaptation, is less clear. Thus, we investigated the effects of nocturnal sleep on the performance of a gross motor adaptation task, i.e. riding an inverse steering bicycle. Twenty-six male p...

Sleep and memory studies often focus on overnight rather than long‐term memory changes, traditionally associating overnight memory change (OMC) with sleep architecture and sleep patterns such as spindles. In addition, (para‐)sympathetic innervation has been associated with OMC after a daytime nap using heart rate variability (HRV). In this study we...

Many studies investigating sleep and memory consolidation have evaluated full-night sleep rather than alternative sleep periods such as daytime naps. This multi-centre study followed up on, and was compared with, an earlier full-night study (Schabus et al., 2004) investigating the relevance of daytime naps for the consolidation of declarative and p...

Introduction Numerous studies indicate memory consolidation during sleep and postulate that memories are less susceptible to interference after sleep. Griessenberger et al. (2013), moreover, found that susceptibility to interference is pronounced in insomniacs in the declarative memory domain only as compared to the procedural domain. However, it i...

For the past two decades, it has generally been accepted that sleep benefits motor memory consolidation processes. This notion, however, has been challenged by recent studies and thus the sleep and motor memory story is equivocal. Currently, and in contrast to the declarative memory domain, a comprehensive overview and synthesis of the effects of p...

See Thibault et al. (doi:10.1093/awx033) for a scientific commentary on this article. Neurofeedback training builds upon the simple concept of instrumental conditioning, i.e. behaviour that is rewarded is more likely to reoccur, an effect Thorndike referred to as the ‘law of effect’. In the case of neurofeedback, information about specific electroe...

Today, there is little doubt concerning the significance of sleep for memory consolidation. Some studies have suggested, however, that overnight memory consolidation as well as their underpinning neural mechanisms might be modulated by general cognitive abilities. In this paper, we used a more specific trait measure of declarative word-pair encodin...

Information processing has been suggested to depend on the current state of the brain as well as stimulus characteristics (e.g. salience). We compared processing of salient stimuli (subject’s own names [SONs] and angry voice [AV] stimuli) to processing of unfamiliar names (UNs) and neutral voice (NV) stimuli across different vigilance stages (i.e....

One of the strongest stimuli to automatically catch attention is a person’s own name (ON). Auditory presentation of the ON has been shown to evoke electrophysiological markers of attention-orienting that even persist in states of diminished consciousness such as sleep (Perrin et al., 1999). Likewise, the emotional content such as familiarity of voi...

Introduction: The suggested functions of sleep are manifold, involving adaptive strategies, physical recovery and more recently "offline" information reprocessing. Methods: Here we now present a study in which the same type of declarative (word-pair learning) and procedural (finger-tapping) task was conducted four times (weeks apart) in the eve...

Sleep has been shown to promote memory consolidation driven by certain oscillatory patterns, such as sleep spindles. However, sleep does not consolidate all newly encoded information uniformly but rather "selects" certain memories for consolidation. It is assumed that such selection depends on salience tags attached to the new memories before sleep...

Among auditory stimuli, the own name is one of the most powerful and it is able to automatically capture attention and elicit a robust electrophysiological response. The subject's own name (SON) is preferentially processed in the right hemisphere, mainly because of its self-relevance and emotional content, together with other personally relevant in...

There is growing evidence of the active involvement of sleep in memory consolidation. Besides hippocampal sharp wave-ripple complexes and sleep spindles, slow oscillations appear to play a key role in the process of sleep-associated memory consolidation. Furthermore, slow oscillation amplitude and spectral power increase during the night after lear...
