DOI: 10.1016/j.cell.2019.08.040
Abstract: Sleep has been implicated in both memory consolidation and forgetting of experiences. However, it is unclear what governs the balance between consolidation and forgetting. Here, we tested how activity-dependent processing during sleep might differentially regulate… read more here.

DOI: 10.1016/j.jsmc.2019.11.002
Abstract: Given the critical role of sleep, particularly sleep slow oscillations, sleep spindles, and hippocampal sharp wave ripples, in memory consolidation, sleep enhancement represents a key opportunity to improve cognitive performance. Techniques such as transcranial electrical… read more here.

DOI: 10.1073/pnas.2122515119
Abstract: One of the most prominent and robust findings in cognitive neuroscience is the strengthening of memories during non-rapid eye movement (NREM) sleep, with slow oscillations (SOs, < 1Hz) playing a critical role in systems-level consolidation.… read more here.

DOI: 10.1093/sleep/zsab072.047
Abstract: The effect of increased cognitive load especially under duress has been known to affect brain rhythms in humans. However, this effect has been shown primarily in the awake brain; the effect of stressful cognitive load… read more here.

DOI: 10.1093/sleep/zsy197
Abstract: Electrophysiological sleep rhythms have been shown to impact human waking cognition, but their spatio-temporal dynamics are not understood. We investigated how slow oscillations (SOs; 0.5-4 Hz) are organized during a night of polysomnographically-recorded sleep, focusing… read more here.

DOI: 10.1111/ejn.14906
Abstract: The systems consolidation of memory during slow‐wave sleep (SWS) is thought to rely on a dialogue between hippocampus and neocortex that is regulated by an interaction between neocortical slow oscillations (SOs), thalamic spindles and hippocampal… read more here.

No difference between slow oscillation up‐ and down‐state cueing for memory consolidation during sleep
Sign Up to like & getrecommendations! Published in 2022 at "Journal of Sleep Research"
DOI: 10.1111/jsr.13562
Abstract: The beneficial effects of sleep for memory consolidation are assumed to rely on the reactivation of memories in conjunction with the coordinated interplay of sleep rhythms like slow oscillations and spindles. Specifically, slow oscillations are… read more here.

Abstract: Background. Reorganization in motor areas have been suggested after motor imagery training (MIT). However, motor imagery involves a large-scale brain network, in which many regions, andnot only the motor areas, potentially constitute the neural substrate… read more here.
