The cat is out of the bag: cortical simulations with 109 neurons, 1013 synapses (2009, result): “These propagation patterns are in agreement with observations made in animals [31][26], providing a measure of validation of the model.”
VSDI: a new era in functional imaging of cortical dynamics (2004, background): “Large, coherent, ongoing activity was also found in the rat somatosensory corte”
A default mode of brain function: A brief history of an evolving idea (2007, background): “In this regard, descriptions of slow fluctuations (nominally, < 1 Hz) in neuronal membrane polarization–so-called up and down states–are intriguing (Petersen et al., 2003; Hahn et al., 2006; Isomura et al., 2006; Luczak et al., 2007).”
The temporal structures and functional significance of scale-free brain activity (2010, positive): “Recent studies suggest that the UDS can also occur during wakefulness when quietly resting or when sleep pressure increases (Petersen et al., 2003; Vyazovskiy et al., 2009).”
Cooperative synapse formation in the neocortex (2009, background): “Moreover, due to a different electro-physiological state of the neural network in vivo (42), the minimum number of simultaneously active presynaptic neurons needed to fire the postsynaptic cell may be lower yet.”
Waking State: Rapid Variations Modulate Neural and Behavioral Responses (2015, positive): “As a result, the postsynaptic targets of SOM- and PV-containing interneurons, namely the apical dendrites and somata of pyramidal neurons, are believed to be disinhibited by movement/reward activation of VIP interneurons (Fu et al., 2014; Lee et al., 2013; Pfeffer et al., 2013; Pi et al., 2013).”
The Restless Brain (2011, neutral): “These include the delta band (1–4 Hz), up-an-down states [ * 0.8Hz; (Hahn et al., 2006; Petersen et al., 2003; Steriade et al., 1993; Watson et al., 2008)], and infraslow ﬂuctuations (ISFs) [0.01 and 0.1Hz (Monto et al., 2008; Vanhatalo et al., 2004)].”
Hippocampal sharp wave bursts coincide with neocortical "up-state" transitions. (2004, background): “During slow wave sleep, the neocortex engages in largely synchronized activity patterns, with alternation of periods of generalized elevated activity (“up-states”) and depressed activity (“down-states”) (e.g., Steriade and Buzsaki 1990; Cowan and Wilson 1994; Timofeev et al. 2001; Petersen et al. 20”
Interactions between Intrinsic and Stimulus-Evoked Activity in Recurrent Neural Networks (2009, background): “Response variability (Mast and Victor, 1991; Arieli et al., 1995 & 1996; Anderson et al., 2000 & 2001; Kenet et al., 2003; Petersen et al., 2003a & b; Fiser, Chiu and Weliky, 2004; MacLean et al., 2005; Yuste et al., 2005; Vincent et al., 2007) is often treated as random noise, generated either by…”
Spontaneous events outline the realm of possible sensory responses in neocortical populations (2009, background): “As previously reported for resting animals (Luczak et al., 2007; Petersen et al., 2003; Poulet and Petersen, 2008), spontaneous global fluctuations in network activity were seen, although the length and depth of downstates was reduced compared to the anesthetized condition (Figures 4A and 4B).”
The Sleep Slow Oscillation as a Traveling Wave (2004, background): “Within small patches of cortex, where only pure neighbor-to-neighbor synaptic propagation can be observed, wave speed is considerably lower (10 –100 mm/sec) (Sanchez- Vives and McCormick, 2000; Compte at al., 2003; Petersen et al., 2003).”
