Neurodegenerative diseases target large-scale human brain networks (2009, background): “On the other hand, ICNs remain detectable during mental effort (Fransson, 2006), and ICN strength and variation influence task performance inside (Fox et al., 2007; Hesselmann et al., 2008) and outside (Seeley et al.”
The temporal structures and functional significance of scale-free brain activity (2010, methodology): “In this study, the authors acquired fMRI signals from a water phantom in the same scanner, the power spectrum of which was close to white noise (see Figure S4 in Fox et al., 2007), which differs significantly from the power spectrum of fMRI signals recorded from the brain (see Figure 5A).”
Parcellation‐dependent small‐world brain functional networks: A resting‐state fMRI study (2009, methodology): “In this study, we first measured functional connectivity (Friston et al., 1993) between any pair of brain regions (defined by the two different brain atlases) by calculating Pearson correlations between the time series of the regions.”
Predictive Coding or Evidence Accumulation? False Inference and Neuronal Fluctuations (2010, background): “This is an important conclusion because the functional role of such ongoing or endogenous activity fluctuations, which have traditionally been neglected in many neurophysiological and theoretical investigations of perceptual inference and decisions, is becoming increasingly evident [22,23,24,25].”
Graph-Based Network Analysis of Resting-State Functional MRI (2010, neutral): “…et al., 2008; Roy et al., 2009; Smith et al., 2009; Yan et al., 2009b), trait variability and behavioral characteristics (Hampson et al., 2006; Fox et al., 2007; Hesselmann et al., 2008; Kelly et al., 2008; Di Martino et al., 2009; Yan et al., 2009a), as well as various clinical populations…”
Divergent network connectivity changes in behavioural variant frontotemporal dementia and Alzheimer's disease. (2010, neutral): “recent studies (Fox et al., 2007; Cohen et al., 2008; Meindl et al., 2009; Shehzad et al., 2009).”
Sleep deprivation reduces default mode network connectivity and anti-correlation during rest and task performance (2012, background): “In support of this, intrinsic activity in motor regions has been shown to account for a significant proportion of the inter-trial variability in activity evoked by a button press task (Fox et al., 2006b), and for variance in behavioural performance (Fox et al., 2007).”
Inter-Individual Differences in Resting State Functional Connectivity Predict Task-Induced BOLD Activity (2010, background): “…were found after learning (Albert et al., 2009; Lewis et al., 2009; Xiong et al., 2009), in relation to specific task demands (Barnes et al., 2009; Fransson, 2006; Hampson et al., 2006; Hasson et al., 2009; Kelly et al., 2008) or conscious and emotional states (Greicius et al., 2008; Harrison et…”
Functional brain networks are dominated by stable group and individual factors, not cognitive or daily variation (2018, background): “One possibility is that they index the presence of multiple neural or cognitive strategies for completing even simple tasks (e.g., how hard to squeeze a hand; Fox et al., 2007; Pearce and Moran, 2012).”
Intrinsic and task-evoked network architectures of the human brain. (2014, positive): “Previous findings identified similarity between resting-state FC and task FC for a small number of brain regions and tasks (Biswal et al., 1995; Fair et al., 2007; Fox et al., 2007; Greicius et al., Each task's whole-brain FC matrix was compared to the resting-state FC matrix (from Figure 4).”
Spontaneous and driven cortical activity: implications for computation. (2009, positive): “Direct contribution of spontaneous activity to intertrial variability in human behavior has also been shown by means of fMRI [43].”
