Hippocampal replay in the awake state: a potential physiological substrate of memory consolidation and retrieval (2011, background): “Hippocampal replay occurs during sharp wave ripples SWRs originate in the hippocampus and are triggered by synchronized activation of pyramidal cells in its CA3 region, leading to characteristic negative potentials (sharp waves) in the stratum radiatum of the CA1 regio”
Theta rhythm of navigation: Link between path integration and landmark navigation, episodic and semantic memory (2005, background): “cycle < 1% of pyramidal cells discharge, whereas up to 16% of the pyramidal cells in the CA3–CA1–subicular complex–EC axis may participate in sharp wave bursts (Chrobak and Buzsáki, 1994, 1996; Csicsvari et al., 2000).”
Dissociating the past from the present in the activity of place cells (2006, background): “The hippocampus, specifically CA3’s recurrent network, is believed to have a circuitry particularly well suited to generate these behaviorally related patterns of activity (McClelland et al., 1995; Rolls, 1996; Hasselmo and McClelland, 1999), and in fact, sharp-wave-ripples originate in CA3 (Csicsva”
Sleep (2007, background): “This hippocampal activity does raise the possibility of a role in consolidation of episodic memory traces (Buzsaki, 1998; Csicsvari et al., 2002; Nadasdy et al., 1999).”
Defined types of cortical interneurone structure space and spike timing in the hippocampus (2005, background): “Thus, a strong excitation from the CA3 area and rhythmic hyperpolarization (Csicsvari et al. 2000) originating from parvalbumin positive basket and bistratified cells (Klausberger et al. 2004), together with a possible contribution of axo-axonal gap junctions between pyramidal cells (Traub et al.…”
Sparseness constrains the prolongation of memory lifetime via synaptic metaplasticity. (2008, methodology): “In the hippocampus, one finds f 10–2 (Csicsvari et al. 2000), whereas the barrel cortex (Brecht and Sakmann 2002) and the visual cortex (Weliky et al. 2003) provide coding ratios with large values of f 0.5.”
The reorganization and reactivation of hippocampal maps predict spatial memory performance (2010, unknown): “In the hippocampus, SWR events have been suggested to assist the stabilization of memory traces 7 , 21 , 22 , 28 , 35 .”
The memory function of sleep (2010, background): “During an individual ripple event only a small subpopulation of pyramidal cells fire — the subpopulation varies between successive ripples, indicating modulation of select neuronal circuit”
Coordinated memory replay in the visual cortex and hippocampus during sleep (2007, background): “1 online), which are prominent high-frequency (80–250 Hz) oscillation events in the hippocampal EE”
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).”
NMDA receptor-dependent multidendrite Ca(2+) spikes required for hippocampal burst firing in vivo. (2014, unknown): “Thus, burst activity arriving from the CA3 region (Csicsvari et al., 2000) is possibly a major determinant of CSs in CA1.”
Reactivation of experience-dependent cell assembly patterns in the hippocampus (2008, background): “SWRs are initiated in the CA3 region and are associated with the synchronized discharge of CA1 and CA3 cells and transient 200-Hz oscillatory patterns (ripples) in the CA1 regio”
Neural syntax: cell assemblies, synapsembles and readers (2010, unknown): “These conditions may be present in the hippocampus during sharp wave ripples (Csicsvari et al., 2000) and in the geniculocortical system during visual transmission (Wang et al., 2010).”
