Involvement of sleep spindles in overnight declarative memory stabilization
ObjectiveNumerous studies point to the involvement of sleep spindles and slow waves in memory processes, particularly in hippocampus-dependent declarative memory. We have shown previously that the…
The effect of cognitive training on subsequent sleep characteristics
Introduction: Several studies have consistently shown that pre-sleep learning produces changes in sleep structure. Whereas the majority of these studies has mainly focused on post-training changes in…
The role of daytime napping in declarative memory performance: a systematic review.
The role of sleep for episodic memory consolidation: Stabilizing or rescuing?
Slow wave sleep induced by GABA agonist tiagabine fails to benefit memory consolidation.
TLDR
Overnight retention of memory tested after sleep the next evening was generally not improved after tiagabine, but on average even lower than after placebo, with this impairing effect reaching significance for procedural sequence finger tapping.
The Role of Sleep in the Selective Reconsolidation of Declarative Memories
TLDR
Observed relationships support the proposed hypothesis suggesting that sleep processes are involved in the reconsolidation of labile memories, and that this reconsolidations may be selective for memories of future relevance.
Brain stimulation during an afternoon nap boosts slow oscillatory activity and memory consolidation in older adults
Opposite Effect of Motivated Forgetting on Sleep Spindles during Stage 2 and Slow Wave Sleep.
TLDR
It is found that both nap and no-nap groups recalled significantly less no-think words in the MF condition compared to the control condition, indicating that sleep spindles are sensitive to the previous MF experiences and suggesting a differential role of sleepSpindles during S2 and SWS in memory processing during sleep.
Learning and sleep-dependent consolidation of spatial and procedural memories are unaltered in young men under a fixed short sleep schedule
Age-Related Changes in Sleep-Dependent Consolidation of VisuoSpatial Memory
Healthy aging is associated with a reduction in slow-wave sleep (SWS), crucial for declarative memory consolidation in young adults; consequently, previously observed benefits of sleep on declarative…

Learning-Dependent Increases in Sleep Spindle Density
TLDR
Results indicate that spindle activity during non-REM sleep is sensitive to previous learning experience, and spindle density was correlated to recall performance both before and after sleep.
Sleep spindles and their significance for declarative memory consolidation.
TLDR
Results indicate that increased sleep stage 2 spindle activity is related to an increase in recall performance and, thus, may reflect memory consolidation in stage 2 sleep.
Daytime Naps, Motor Memory Consolidation and Regionally Specific Sleep Spindles
TLDR
It is demonstrated that motor memories are dynamically facilitated across daytime naps, enhancements that are uniquely associated with electrophysiological events expressed at local, anatomically discrete locations of the brain.
The memory function of sleep
TLDR
Sleep has been identified as a state that optimizes the consolidation of newly acquired information in memory, depending on the specific conditions of learning and the timing of sleep, through specific patterns of neuromodulatory activity and electric field potential oscillations.
Twenty-four hours retention of visuospatial memory correlates with the number of parietal sleep spindles
A daytime nap containing solely non-REM sleep enhances declarative but not procedural memory
Dissociable learning-dependent changes in REM and non-REM sleep in declarative and procedural memory systems
An ultra short episode of sleep is sufficient to promote declarative memory performance
TLDR
It is suggested that the mere onset of sleep may initiate active processes of consolidation which – once triggered – remain effective even if sleep is terminated shortly thereafter.
Sleep-Dependent Facilitation of Episodic Memory Details
TLDR
It is suggested that sleep may preferentially benefit contextual aspects of memory, supported by sleep-spindle oscillations, and that the temporal order of initial learning differentially determines subsequent offline consolidation.
