Selective Experience Replay for Lifelong Learning (2018, background): “Surprise Unexpected events have been shown to be connected to replay in rodents (McNamara et al. 2014; Cheng and Frank 2008) and surprise has a convenient counter-part in incremental reinforcement learning methods like Q-learning.”
Awake replay of remote experiences in the hippocampus (2009, positive): “We and others have found that novel experiences generate a long lasting increase in neuronal excitability and neuronal coordination for the cells active during those experiences13, 17, 20, 30.”
Hippocampal Replay is Not a Simple Function of Experience (2010, background): “However, others have found preferential reactivation (Cheng and Frank, 2008) and replay (Foster and Wilson, 2006) in novel environments, suggesting that the frequency of replay may be inversely related to experience and therefore the relationship between replay content and experience may not be…”
Hippocampal place cells construct reward related sequences through unexplored space (2015, positive): “Moreover, these findings agree with previous studies showing replay can be modulated by reward (Cheng and Frank, 2008; Singer and Frank, 2009; Pfeiffer and Foster, 2013) but extend this modulatory influence to preplay of future, goal-oriented routes.”
About sleep's role in memory. (2013, background): “They also occur conjointly with SW-Rs that are observed at somewhat lower rates during wakefulness than during SWS (159, 191, 870).”
Network dynamics underlying the formation of sparse, informative representations in the hippocampus (2008, unknown): “This complements previous work showing that CA1 cells are reactivated together both during and after a novel experience (Cheng and Frank, 2008; O’Neill et al., 2008).”
Automatic Recall Machines: Internal Replay, Continual Learning and the Brain (2020, background): “In the brain, experiences associated with higher surprise and thus representational change also increase the intensity of replay during and after the experience [Cheng and Frank, 2008, O’Neill et al., 2008].”
The reorganization and reactivation of hippocampal maps predict spatial memory performance (2010, unknown): “An increased incidence of high frequency SWR-like oscillations has been also reported during exploration of novel environments and these events have been suggested to promote the stabilization of new place maps 43 .”
Rewarded Outcomes Enhance Reactivation of Experience in the Hippocampus (2009, unknown): “SWRs occur largely during sleep and awake immobility (Buzsáki et al., 1983; O’Neill et al., 2006; Cheng and Frank, 2008) and are thought to be important for spatial learning and memory formation (Redish and Touretzky, 1998; Redish, 1999; Samsonovich and Ascoli, 2005; Nakashiba et al.”
High-density, long-lasting, and multi-region electrophysiological recordings using polymer electrode arrays (2018, unknown): “SWR detection and modulation SWRs were detected as previously described (Cheng and Frank, 2008).”
