Generalization Through the Recurrent Interaction of Episodic Memories (2012, background): “…of transitivity, and its disruption by hippocampal system damage, has been observed by numerous studies (Dusek & Eichenbaum, 1997; Greene et al., 2001; Heckers et al., 2004; McGonigle & Chalmers, 1977; Moses et al., 2006; Ryan et al., 2009; C. Smith & Squire, 2005; Van Elzakker et al., 2003).”
Hippocampal replay in the awake state: a potential physiological substrate of memory consolidation and retrieval (2011, background): “Reactivation of cell pairs after an experience was first studied during slee”
Lifelong Generative Modeling (2017, background): “While strongly motivated by biological rehearsal processes [119, 53, 58, 110], these generative replay strategies fail to efficiently use previous learning and simply re-learn each new joint task from scratch.”
Hippocampal Replay is Not a Simple Function of Experience (2010, background): “Whereas previous studies (Wil- son and McNaughton, 1994; Jackson et al., 2006; O’Neill et al., 2006; Karlsson and Frank, 2009) have found increasing replay with experience, these studies did not compare tasks with different behavioral requirements in which parts of the environment were experienced m”
Reactivation of Hippocampal Cell Assemblies: Effects of Behavioral State, Experience, and EEG Dynamics (1999, background): “At the network level, both the spatial (Wilson and McNaughton, 1994) and temporal (Skaggs and McNaughton, 1996) structures of neuronal firing-rate correlations that appear in a hippocampal neural ensemble during behavior are significantly preserved in subsequent slow wave sleep (SWS), at least for…”
Theta rhythm of navigation: Link between path integration and landmark navigation, episodic and semantic memory (2005, background): “However, many more episodes are compressed into the 150 ms sharp wave event than in several seconds of theta (Wilson and McNaughton, 1994; Skaggs and McNaughton, 1996; Kudrimoti et al., 1999; Nádasdy et al., 1999; Lee and Wilson, 2002), creating opportunities for crossing episodes at the timescale…”
On the methods for reactivation and replay analysis (2020, methodology): “(a) Cross-correlograms The first method to posit that the temporal order of hippocampal sequences duringbehaviourare later ‘replayed’during sleep used cross-correlograms (CCG) between pairs of neurons [18].”
Methodological Considerations on the Use of Template Matching to Study Long-Lasting Memory Trace Replay (2006, background): “…to play an important role in the consolidation process of certain types of memory (Pavlides and Winson, 1989; Wilson and McNaughton, 1994; Skaggs and McNaughton, 1996; Nadasdy et al., 1999; Dave and Margoliash, 2000; Louie and Wilson, 2001; Hoffman and McNaughton, 2002; Lee and Wilson,…”
Learned material content and acquisition level modulate cerebral reactivation during posttraining rapid-eye-movements sleep (2003, result): “Consistent with this hypothesis, several animal studies have shown that neural activity expressed during waking behavior is reinstated during subsequent sleep (e.g., Wilson and McNaughton, 1994; Skaggs and McNaughton, 1996; Qin et al., 1997; Nadasdy et al., 1999; Louie and Wilson, 2001).”
Reactivation of experience-dependent cell assembly patterns in the hippocampus (2008, background): “In addition, there is evidence that the firing sequences of place cells representing movement paths are reactivated during sleep after the animal follows stereotyped movement paths (for example, on linear tracks or circular mazes”
Persistent schema-dependent hippocampal-neocortical connectivity during memory encoding and postencoding rest in humans (2010, background): “For instance, task-related neuronal spiking patterns are spontaneously “replayed” during postlearning off-line periods such as awake resting (16, 17) and sleep (9, 18, 19).”
