Default mode network activity in schizophrenia studied at resting state using probabilistic ICA. (2012, methodology): “One previous report using ICA to compare schizophrenia patients and healthy controls did find a stronger correlation of the healthy subjects' network with their default mode network template (Garrity et al., 2007).”
Reduced resting-state brain activity in the "default network" in normal aging. (2008, background): “Most resting-state fMRI studies investigating the DMN performed group analyses on one preselected spatial pattern of brain regions identified as being part of the DMN (e.g., on the best fit to the DMN of every single subject) (Esposito et al. 2006; Garrity et al. 2007; Greicius et al. 2007).”
Discriminative analysis of resting-state functional connectivity patterns of schizophrenia using low dimensional embedding of fMRI (2010, background): “…et al. found altered temporal frequency and spatial location of the default network associated with schizophrenia, and suggested that these altered temporal fluctuations in patients might result from a change in the connectivity of some key regions with other brain networks (Garrity et al., 2007).”
Abnormal functional connectivity of default mode sub-networks in autism spectrum disorder patients (2010, background): “These 3 DM-SNs were previously identified in other ICA studies of resting state and cognitive fMRI studies in both non-clinical samples and schizophrenia patients (e.g. Assaf et al., 2009; Calhoun et al., 2008a; Damoiseaux et al., 2006; Esposito et al., 2006; Garrity et al., 2007; Jafri et al., 2008”
Transient and linearly graded deactivation of the human default-mode network by a visual detection task (2008, positive): “It has also been shown thatDMNdeactivation ismodulated in clinical populations, such as those with an autistic-spectrum disorder (Kennedy et al., 2006), schizophrenia (Garrity et al., 2007; Harrison et al., 2007) and the elderly (Persson et al., 2007).”
The impact of global signal regression on resting state correlations: Are anti-correlated networks introduced? (2008, positive): “…studies have attributed disruptions in the connections between nodes of the default mode network to disorders such as Alzheimer's disease (Greicius et al., 2004), schizophrenia (Garrity et al., 2007), ADHD (Sonuga-Barke and Castellanos, 2007) and autism (Just et al., 2007; Kennedy et al., 2006).”
Default-mode brain dysfunction in mental disorders: a systematic review. (2009, background): “ICA analysis has also revealed differences in both spatial and temporal connectivity of the DMN during an auditory oddball task (Garrity et al., 2007).”
Fractionating the Default Mode Network: Distinct Contributions of the Ventral and Dorsal Posterior Cingulate Cortex to Cognitive Control (2011, methodology): “Subsequently, three canonical restingstate independent components were identified using a template matching procedure (Garrity et al., 2007) with reference to the original resting Figure 1.”
State-space model with deep learning for functional dynamics estimation in resting-state fMRI (2016, positive): “…Wang et al., 2007; Zhang et al., 2012; Chase, 2014), autism spectrum disorder (Monk et al., 2009; Khan et al., 2013), schizophrenia (Liang et al., 2006; Zhou et al., 2007; Garrity et al., 2007; Lynall et al., 2010), and depression (Anand et al., 2005; Greicius et al., 2007; Craddock et al., 2009).”
Selective aberrant functional connectivity of resting state networks in social anxiety disorder (2010, background): “Resting state brain networks were often shown to present abnormalities in many neuropsychiatric disorders (Calhoun et al., 2008; 2009; Garrity et al., 2007; Greicius et al., 2004; 2007; Mohammadi et al., 2009; Seeley et al., 2009; Sorg et al., 2007).”
Deriving reproducible biomarkers from multi‐site resting‐state data: An Autism‐based example (2016, background): “Numerous studies have linked variations in brain functional architecture measured from R-fMRI to behavioral traits and mental health conditions such as Alzheimer disease ( e.g. [7, 8], Schizophrenia ( e.g. [9, 10, 11, 12]), ADHD, autism ( e.g. [13]) and others ( e.g. [14]).”
Disrupted small-world networks in schizophrenia. (2008, background): “, 2004) and temporal lobes (Fletcher et al., 1999b; Garrity et al., 2007) were disturbed in this disorder.”
Modulation of temporally coherent brain networks estimated using ICA at rest and during cognitive tasks (2008, positive): “Two TCNs have been previously studied in schizophrenia [Bluhm et al., 2007; Calhoun et al., 2004a; Garrity et al., 2007]; one includes bilateral temporal lobe regions, which have previously been used to discriminate healthy controls from patients with schizophrenia [Calhoun et al., 2004a].”
