Replay in Deep Learning: Current Approaches and Missing Biological Elements (2021, neutral): “…used methods for analyzing replay, such as template matching, principal component analysis, and independent component analysis, have shown high similarity but not an exact match, between activation patterns during waking and sleep (Lee & Wilson, 2002; Louie & Wilson, 2001; Peyrache et al., 2009).”
About sleep's role in memory. (2013, background): “In a few studies, signs of neuronal reactivations have been observed also during REM sleep (536, 544, 744, 893, 935, 936).”
Slow-wave sleep and the consolidation of long-term memory (2010, background): “Signs of neuronal reactivation have mostly been observed during SWS, although in some cases this has also been seen during REM sleep (Louie and Wilson 2001).”
Sleep (2007, background): “Declarative memory uses the hippocampus and adjacent temporal lobe structures, and, therefore, these structures have been the focus of physiologically based sleep-learning experimenters, including those observing neuronal unit activity during sleep (Louie and Wilson, 2001).”
Integrating memories to guide decisions (2015, background): “Indeed, similar retrospective ‘‘replay’’ phenomena have also been reported, in which place cells represent positions where the animal has been in the past, including reverse replay behind the animal [35], or replaying spatially remote routes while the animal is pausing or asleep [36,37].”
The memory function of sleep (2010, background): “Such neuronal re-activation of ensemble activity mostly occurs during SWS (it is rarely observed during REM slee”
Complementary Learning Systems (2014, background): “Studies have implicated that the information flow is directed from neocortical areas to the hippocampus during REM, where a complementary process to SWS for consolidating hippocampal memory may be at play (Buzsaki, 2002; Louie & Wilson, 2001; Wilson & McNaughton, 1994).”
New experiences enhance coordinated neural activity in the hippocampus. (2008, positive): “Neurons with overlapping place fields tend to fire together when the animal is located outside the place fields during later periods of sleep (Pavlides and Winson, 1989; Wilson and McNaughton, 1994; Skaggs and McNaughton, 1996; Nadasdy et al., 1999; Kudrimoti et al., 1999; Louie and Wilson, 2001; Le”
Sequence Learning and the Role of the Hippocampus in Rodent Navigation (2012, positive): “First shown in sleep [48–50], where they were hypothesized to be involved in long-term memory consolidation [51], they have more recently been shown to occur robustly during the awake state as well.”
The restless engram: consolidations never end. (2012, background): “Replay in REM was also reported during periods of theta modulation with a “read-out” rate close to real time (Louie & Wilson 2001).”
