“…In striking contrast, Scullin [39]r eported a negative correlation between the amount of SWS and memory for word pairs in older adults, whereas a positive correlation between declarative memory consolidation and SWS was only observed in younger adults. Similarly, in younger participants, SWA during non-REM sleep correlated positively with declarative memory consolidation of a word-list learning task and oscillatory power in the sleep spindle range [40]. In addition, the slow oscillation band and sleep spindle density have been related to integrating new memories into semantic memory [41,42].…”

Sleep benefits memory consolidation. Previous theoretical accounts have proposed a differential role of slow-wave sleep (SWS), rapid-eye-movement (REM) sleep, and stage N2 sleep for different types of memories. For example the dual process hypothesis proposes that SWS is beneficial for declarative memories, whereas REM sleep is important for consolidation of non-declarative, procedural and emotional memories. In fact, numerous recent studies do provide further support for the crucial role of SWS (or non-REM sleep) in declarative memory consolidation. However, recent evidence for the benefit of REM sleep for non-declarative memories is rather scarce. In contrast, several recent studies have related consolidation of procedural memories (and some also emotional memories) to SWS (or non-REM sleep)-dependent consolidation processes. We will review this recent evidence, and propose future research questions to advance our understanding of the role of different sleep stages for memory consolidation.

“…In particular, the parallel activation of specific neocortical and hippocampal networks during wakefulness, which represent, respectively, long-term and temporary store in declarative memory system, should induce a selective reactivation of the same circuits during subsequent sleep [10, 11, 54, 55]. Several findings support this model pointing out to the crucial role played by sleep-specific brain activity in favouring consolidation of memory traces [19, 56–60]. According to the model, slow oscillations originated during SWS in neocortical networks [61] allow the formation of spindle-ripple events that mediates the hippocampus-to-neocortex transfer of memory information.…”

“…A neural re-activation during sleep has been observed in rats after simple spatial tasks [54, 67, 68]. Moreover, the engagement in a learning task results in increased slow oscillations, spindles activity, and hippocampal ripples that seem to be associated with an improved performance [19, 53, 56, 57, 60, 62]. …”

Is Sleep Essential for Neural Plasticity in Humans, and How Does It Affect Motor and Cognitive Recovery?

There is a general consensus that sleep is strictly linked to memory, learning, and, in general, to the mechanisms of neural plasticity, and that this link may directly affect recovery processes. In fact, a coherent pattern of empirical findings points to beneficial effect of sleep on learning and plastic processes, and changes in synaptic plasticity during wakefulness induce coherent modifications in EEG slow wave cortical topography during subsequent sleep. However, the specific nature of the relation between sleep and synaptic plasticity is not clear yet. We reported findings in line with two models conflicting with respect to the underlying mechanisms, that is, the “synaptic homeostasis hypothesis” and the “consolidation” hypothesis, and some recent results that may reconcile them. Independently from the specific mechanisms involved, sleep loss is associated with detrimental effects on plastic processes at a molecular and electrophysiological level. Finally, we reviewed growing evidence supporting the notion that plasticity-dependent recovery could be improved managing sleep quality, while monitoring EEG during sleep may help to explain how specific rehabilitative paradigms work. We conclude that a better understanding of the sleep-plasticity link could be crucial from a rehabilitative point of view.

“…Several studies show that sleep related retention in a wordpair task was positively correlated with sleep spindle activity (e.g., electroencephalography [EEG] power 12-15 Hz) or density (number of spindles per min of sleep). [3][4][5][6] In addition, an increase of sleep spindle density was found after word-pair learning, 7 in particular, when the encoding was difficult. 6 This increase of spindle density was correlated with sleep related changes in recall performance.…”
