Awake replay of remote experiences in the hippocampus (2009, neutral): “This process is thought to involve rapid encoding in highly plastic hippocampal circuits followed by a consolidation process in which hippocampal representations are 'reactivated', allowing these patterns to be engrained in less-plastic hippocampal-neocortical circuit”
The Role of Sleep in Cognition and Emotion (2009, background): “Buzsaki (1996) has since advanced on these ideas, proposing a model of consolidation that involves two stages or states of hippocampal activity, the first involving a mode of “recording” during wake, which shifts to a second stage, involving “playback” mode during NREM SWS, specifically during…”
Hippocampal sharp wave‐ripple: A cognitive biomarker for episodic memory and planning (2015, background): “Second, SPW-Rs are the most synchronous events in the mammalian brain, associated with a robustly enhanced transient excitability in the hippocampus and its partner structures (Buzs aki 1986; Chrobak and Buzs aki, 1994; Csicsvari et al., 1999b).”
Neuronal synchrony: a versatile code for the definition of relations? (1999, unknown): “Such cycle skipping is a well known phenomenon of oscillatory processes in the hippocampus (Buzsaki and Chrobak, 1995; Buzsaki, 1996) and may be of functional significance rather than a reflection of noise fluctuations.”
Place-selective firing of CA1 pyramidal cells during sharp wave/ripple network patterns in exploratory behavior. (2006, background): “Furthermore, it has been hypothesized that the key pattern for consolidation of learned information is SWRs, not sleep per se ( Buzsaki, 1989, 1996; Nadasdy et al., 1999; Kudrimoti et al., 1999).”
Hippocampal CA3 Output is Crucial for Ripple-Associated Reactivation and Consolidation of Memory (2009, unknown): “…and the ripple-associated, off-line “reactivation” of experience-dependent coordinated activity patterns of CA1 cells are crucial for memory consolidation (Buzsaki, 1996; Ji and Wilson, 2007; Lee and Wilson, 2002; Siapas and Wilson, 1998; Skaggs and McNaughton, 1996; Wilson and McNaughton, 1994).”
Disruption of ripple-associated hippocampal activity during rest impairs spatial learning in the rat (2009, background): “Sharp wave-ripple events have specifically been proposed to underlie the gradual transfer of memories from hippocampus to cortex, providing active communication between these structures during rest periods (Buzsaki, 1996).”
Coordinated interactions between hippocampal ripples and cortical spindles during slow-wave sleep. (1998, background): “Wilson Center for Learning and Memory Department of Brain and Cognitive Sciences and Department of Biology Massachusetts Institute of Technology Cambridge, Massachusetts 02139 term synaptic changes (Bliss and Collingridge, 1993) that are believed to be necessary for the formation and maintenance of ”
