Changes in Emotional Responses to Aversive Pictures Across Periods Rich in Slow-Wave Sleep Versus Rapid Eye Movement Sleep

Ullrich Wagner, Stefan Fischer, Jan Born
2002 Psychosomatic Medicine  
After the intervals, subjects rated new pictures together with old pictures already presented before the interval. Sleep was recorded polysomnographically.  ...  The present study compared processing pictures with negative emotional impact over intervals covering either early sleep dominated by slow-wave sleep (SWS) or late REM sleep-dominated sleep.  ...  film was reduced after REM-deprived sleep compared with non-REM-deprived or undisturbed sleep (10) .  ...

Role of sleep for encoding of emotional memory

Kosuke Kaida, Kazuhisa Niki, Jan Born
2015 Neurobiology of Learning and Memory  
Total sleep deprivation (TSD) has been consistently found to impair encoding of information during ensuing wakefulness, probably through suppressing NonREM (non-rapid eye movement) sleep.  ...  TSD significantly decreased both the rate of correctly recognized pictures and of recalled frames associated with the pictures.  ...  This effect has been attributed to the loss of non-rapid eye movement sleep (NonREM) rather than REM sleep during TSD before learning, and specifically to functions of slow waves (0.5-4 Hz) and spindles  ...

Selective REM-Sleep Deprivation Does Not Diminish Emotional Memory Consolidation in Young Healthy Subjects

Jarste Morgenthaler, Christian D. Wiesner, Karoline Hinze, Lena C. Abels, Alexander Prehn-Kristensen, Robert Göder, Todd W. Troyer
2014 PLoS ONE  
The aim of this study was to investigate this hypothesis using selective REM-sleep deprivation. We used a recognition memory task in which participants were shown negative and neutral pictures.  ...  Sleep enhances memory consolidation and it has been hypothesized that rapid eye movement (REM) sleep in particular facilitates the consolidation of emotional memory.  ...  The technique of REM-sleep deprivation is therefore an interesting approach to also analyze sleep-related emotional memory processes.  ...

Sleep-deprived residents and rapid picture naming performance using the Mobile universal lexicon evaluation system (MULES) test

2021 eNeurologicalSci  
Many of the factors captured by MULES may be abnormal in sleep-deprived residents. This study investigates the effect of sleep deprivation in post-call residents on MULES performance.  ...  The MULES is a novel test for effects of sleep deprivation on neurocognition and vision pathways. Sleep deprivation significantly worsens MULES performance.  ...  The authors have no financial interests. Additional disclosure: Dr. Laura J. Balcer is editor of the Journal of Neuro-Ophthalmology.  ...

Overnight emotional adaptation to negative stimuli is altered by REM sleep deprivation and is correlated with intervening dream emotions

To evaluate the impact of REM sleep deprivation (REMD) and the presence of dream emotions on a possible emotional adaptation (EA) function, 35 healthy subjects randomly assigned to REMD (n = 17; mean age  ...  A correlation between the emotional intensities of the morning dream and the morning picture ratings supports a possible emotional carry-over effect.  ...  ACK NOWLEDG EMENTS The research was supported by grants to Tore Nielsen from the Canadian Institutes of Health Research and the Natural Sciences and Engineering Research Council of Canada, and by a Canada  ...

Overnight therapy? The role of sleep in emotional brain processing

Matthew P. Walker, Els van der Helm
2009 Psychological bulletin  
Furthermore, a rapid eye movement (REM) sleep hypothesis of emotional-memory processing is proposed, the implications of which may provide brain-based insights into the association between sleep abnormalities  ...  On the basis of the unique neurobiology of sleep, the authors outline a model describing the overnight modulation of affective neural systems and the (re)processing of recent emotional experiences, both  ...  In fact, participants also rated these picture stimuli on the basis of arousal strength.  ...

Differential effects of sleep on explicit and implicit memory for potential trauma reminders: findings from an analogue study

M. Roxanne Sopp, Alexandra H. Brueckner, Sarah K. Schäfer, Johanna Lass-Hennemann, Tanja Michael
2019 European Journal of Psychotraumatology  
Conclusions: The current findings support a protective role of sleep in trauma memory processing, which may be evident after the first night of sleep post-trauma.  ...  Recent findings suggest that disruptions of sleep-related memory processing are involved in the development of posttraumatic stress symptoms.  ...  The authors found that sleep deprivation was associated with a reduced number of intrusions on the first day of ambulatory assessment.  ...

Thus, the goal of the current project is to investigate the influence of sleep on emotional reactivity using multiple simultaneous measures.  ...  Results: Across the sessions, both valence ratings (t=2.043, p=0.046) and skin conductance response (t=-4.052, p<0.001) were preserved for negative pictures in the nap group relative to the wake group.  ...  error monitoring was impaired after a night of experimental sleep fragmentation which reduces the amount of both slow wave sleep (SWS) and rapid-eye-movement sleep (REMS).  ...

For centuries, the functions of sleep have been researched. Multiple theories have been developed, but even now, scientists are unable to produce a conclusive explanation as to why we sleep.  ...  It is evident that sleep is vital, as even in animals, it has been argued that sleep deprivation leads to serious consequences.  ...  Subjects deprived of REM sleep performed worse than subjects deprived of stage 4 sleep. 24 Interestingly, another study measured semantic processing in all stages of sleep individually avoiding sleep  ...
