Hippocampal replay in the awake state: a potential physiological substrate of memory consolidation and retrieval (2011, background): “, which reinforced the idea that sleep is a privileged state for memory consolidation processe”
Awake replay of remote experiences in the hippocampus (2009, positive): “This process is thought to involve rapid encoding in highly plastic hippocampal circuits followed by a consolidation process where hippocampal representations are “reactivated”, allowing these patterns to be engrained in less plastic hippocampal – neocortical circuits3, 4.”
Hippocampal Replay is Not a Simple Function of Experience (2010, background): “This interpretation is consistent with the observation that reactivation and backward replay events are more frequent in novel environments (Foster and Wilson, 2006; Cheng and Frank, 2008), which could be a mechanism to rapidly acquire a complete representation.”
Post-learning hippocampal dynamics promote preferential retention of rewarding events (2016, background): “According to some models of memory consolidation, neural processes that occur after learning can also influence retention (Carr et al. 2011; Káli and Dayan 2004; Sutherland and McNaughton, 2000).”
Hippocampal sharp wave bursts coincide with neocortical "up-state" transitions. (2004, background): “Brain activity during sleep or idle periods may be crucial for memory processes (Plihal and Born 1999; Stickgold et al. 2000; Sutherland and McNaughton 2000; Maquet 2001).”
Learning-Dependent Increases in Sleep Spindle Density (2002, background): “This reactivation was mostly observed during non-REM sleep (Sutherland and McNaughton, 2000), although also REM sleep-associated reprocessing has been observed in one study (Louie and Wilson, 2001).”
The reorganization and reactivation of hippocampal maps predict spatial memory performance (2010, positive): “Reactivation of behaviorally-governed neuronal patterns during rest periods has been suggested to be involved in memory consolidation 29 , 30 .”
Slow-Wave Sleep-Imposed Replay Modulates Both Strength and Precision of Memory (2014, background): “One component of memory consolidation is replay, where the activity of neural ensembles that occurred during initial learning is repeated during post-training periods including SWS(Pavlides and Winson, 1989; Sutherland and McNaughton, 2000; Bendor and Wilson, 2012).”
The organization of recent and remote memories (2005, background): “In a series of important experiments, McNaughton, Wilson and colleagues showed that coordinated replay occurs in the hippocampus and in both hippocampal– cortical and cortico-cortical network”
Network dynamics underlying the formation of sparse, informative representations in the hippocampus (2008, neutral): “This allowed us to determine whether the changes in rates that we found were specific to the spatial setting and whether these changes persisted after the initial experience in the environment into periods that have been associated with memory consolidation (Buzsáki, 1986; Buzsáki et al., 1992; Suth”
