Measuring and manipulating brain connectivity with resting state functional connectivity magnetic resonance imaging (fcMRI) and transcranial magnetic stimulation (TMS) (2012, background): “1B) and other TMS–PET studies have reported contralateral decreases in motor cortex activity in response to ipsilateral stimulation (Fox et al., 1997; Fox et al., 2006c).”
Is the ADHD brain wired differently? A review on structural and functional connectivity in attention deficit hyperactivity disorder (2010, background): “Another potential difficulty with the analysis of resting-state fMRI is that resting-state connectivity shows prominent very low frequency (<0.1 Hz) oscillations that are hypothesized to provide temporal synchrony between brain regions (Fox et al., 2006; Sonuga-Barke and Castellanos, 2007].”
Conn: A Functional Connectivity Toolbox for Correlated and Anticorrelated Brain Networks (2012, neutral): “Functional connectivity has been investigated in block (e.g., Hampson et al., 2002; Koshino et al., 2005) and event-related (Aizenstein et al., 2009; Fox et al., 2006; Rissman et al., 2004; Siegle et al., 2007) fMRI activation designs.”
A method for using blocked and event-related fMRI data to study "resting state" functional connectivity (2007, background): “Based on previous results that suggest a linear superposition of task activity and spontaneous BOLD fluctuations (Arfanakis et al., 2000; Fox et al., 2006b), it may be assumed that if taskinduced variance is adequately removed from an event-related design data set then the remaining residual signal…”
Mapping the Structural Core of Human Cerebral Cortex (2008, background): “A major feature of cortical functional connectivity is the default network [12–18], a set of dynamically coupled brain regions that are found to be more highly activated at rest than during the performance of cognitively demanding tasks.”
Analysis of a large fMRI cohort: Statistical and methodological issues for group analyses (2007, neutral): “Part of this variability may be related to physiological fluctuations, motion, resting-state activity (Fox et al., 2006), and more generally, what is usually called structured noise (Lund et al.”
Sleep deprivation reduces default mode network connectivity and anti-correlation during rest and task performance (2012, background): “…based on reports that they belong to putative sub-networks of the ACN: the insula is implicated in a salience network (Seeley et al., 2007; Sridharan et al., 2008); the IPS in the dorsal attention network; and the TPJ in the ventral attention network (Corbetta and Shulman, 2002; Fox et al., 2006a).”
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].”
Impairment and compensation coexist in amnestic MCI default mode network (2010, methodology): “…intrinsic architecture of large-scale brain systems, including the default mode network (DMN), attention network, visual network, auditory–phonological network, and motor network (Biswal et al., 1995; Damoiseaux et al., 2006; Fransson, 2005; Fox et al., 2005, 2006a; Hampson et al., 2002).”
Methods for cleaning the BOLD fMRI signal (2016, positive): “The rationale of this approach is that spontaneous fluctuations during the resting state can serve as a valid approximation of all sources of signal variance that may obscure taskrelated activity, not only including motion-related signals and physiological cardiac and respiratory fluctuations but al”
The impact of global signal regression on resting state correlations: Are anti-correlated networks introduced? (2008, positive): “These fluctuations are often correlated between functionally related areas and can occur either on top of task-induced signal modulations (Fox et al., 2006) or in the absence of an explicit task (Biswal et al.”
The effect of resting condition on resting-state fMRI reliability and consistency: A comparison between resting with eyes open, closed, and fixated (2013, methodology): “…with radiuses of 4 mm were generated based on the coordinates provided in the 2010 study by Van Dijk et al. (for more information on these seeds see (Buckner et al., 2008; Corbetta and Shulman, 2002; Fox et al., 2005, 2006; Fransson and Marrelec, 2008; Greicius et al., 2003; Raichle et al., 2001).”
