Awake replay of remote experiences in the hippocampus (2009, neutral): “because SWRs propagate from the hippocampus to adjacent cortical region”
About sleep's role in memory. (2013, background): “SW-Rs may conversely promote LTP and spike timedependent plasticity in hippocampal circuits (97, 159, 241, 640, 777).”
Neurophysiological and Computational Principles of Cortical Rhythms in Cognition (2010, background): “(208) and others showed that sharp-wave ripples appear to represent an example of sparsely synchronized oscillation, with both pyramidal cells and interneurons showing a high degree of irregularity and firing intermittently at much lower firing rates than field oscillations (100–200 Hz), and pyramid”
The Ventral Striatum in Off-Line Processing: Ensemble Reactivation during Sleep and Modulation by Hippocampal Ripples (2004, methodology): “Pattern recurrence in the hippocampus appears especially strong during high-frequency (ϳ200 Hz) EEG events called ripples, which are coupled to sharp waves (Buzsáki, 1986; Kudrimoti et al., 1999).”
Hippocampus Leads Ventral Striatum in Replay of Place-Reward Information (2009, background): “Sleep phase–dependent reactivation was computed for sessions that showed more than 4 min of REM and QW-SWS in each rest episode (n = 13).”
Place-selective firing contributes to the reverse-order reactivation of CA1 pyramidal cells during sharp waves in open-field exploration (2007, background): “SWR network patterns, manifested as negative potentials (sharp waves) in the CA1 stratum radiatum, are triggered by synchronized activation of CA3 pyramidal cells (Buzsaki, 1986; Csicsvari et al., 2000).”
Network dynamics underlying the formation of sparse, informative representations in the hippocampus (2008, unknown): “Given the association between SWRs and memory consolidation (Buzsáki, 1986; Buzsáki et al., 1992), our results provide a mechanism whereby newly learned information could be preferentially consolidated after the experience.”
Spatial representations of granule cells and mossy cells of the dentate gyrus (2017, background): “These reactivations are generated through the coordinated firing of recurrently connected CA3 cells (Buzsáki, 1986), but the preferential firing of granule cells during sleep suggests a role of granule cells in the consolidation process.”
Sleep to Remember (2006, background): “They are superimposed upon ripple activity, which is a high-frequency local field potential oscillation (100–300 Hz) originating in CA1 (Buzsáki 1986; Chrobak and Buzsáki 1994, 1996).”
