Functional brain networks are dominated by stable group and individual factors, not cognitive or daily variation (2018, background): “, 1997), but with activations proportional to task load like control systems (McKiernan et al., 2003; Singh and Fawcett, 2008) and with peripheral position in network graphs like processing systems (Gratton et al.”
Echoes of the Brain within the Posterior Cingulate Cortex (2012, background): “Functionally distinct but spatially overlapping subregions exist within posterior cingulate cortex When attention is focused externally, rapid and reactive deactivation is usually observed across the PCC (Singh and Fawcett, 2008).”
The role of the posterior cingulate cortex in cognition and disease. (2014, background): “In the healthy brain, the magnitude of reactive changes in PCC activity is related to cognitive load (Singh and Fawcett, 2008), and a failure of appropriate deactivation is associated with inefficient cognitive function in both the healthy and damaged brain (e.g. Weissman et al., 2006; Sonuga-Barke…”

Using Dual Regression to Investigate Network Shape and Amplitude in Functional Connectivity Analyses (2017, methodology): “…the DMN, measured as the standard deviation of the BOLD signal timecourse, is related to task-load during brain activation (McKiernan et al., 2003; Singh and Fawcett, 2008) and is sensitive to diﬀerent resting state conditions (eyes open with and without ﬁxation vs. eyes closed; Yan et al., 2009…”
Fractionating the Default Mode Network: Distinct Contributions of the Ventral and Dorsal Posterior Cingulate Cortex to Cognitive Control (2011, background): “Although the region is a core part of the DMN that deactivates on many cognitive tasks, it shows rapid and highly reactive changes in brain activation that depend on cognitive demands (Singh and Fawcett, 2008; Pyka et al., 2009).”
The neural activity of auditory conscious perception (2025, unknown): “Such a decrease is unsurprising, as the default mode has been shown to deactivate in response to task demands, internal planning, and working memory (Li et al., 2007, 2019; Miller et al., 2009; Ossandón et al., 2011; Singh and Fawcett, 2008; Smallwood et al., 2012; Weissman et al., 2006).”
