“…Additionally, reductions in task-related default network suppression and altered FC have been observed with advancing age (Andrews-Hanna et al, 2007; Damoiseaux et al, 2008; Grady et al, 2010; Hafkemeijer, van der Grond, & Rombouts, 2012; Sala-Llonch et al, 2012; Sambataro et al, 2010; Stevens, Hasher, Chiew, & Grady, 2008; Turner & Spreng, 2015). These findings complement whole brain resting-state FC (RSFC) observations of a dedifferentiation of network connectivity with age, with increases in RSFC between large-scale brain systems in older adults (Betzel et al, 2014; Chan, Park, Savalia, Petersen, & Wig, 2014; Geerligs, Renken, Saliasi, Maurits, & Lorist, 2015; Grady, Sarraf, Saverino, & Campbell, 2016; Meunier, Achard, Morcom, & Bullmore, 2009; Onoda & Yamaguchi, 2013). It is unclear, however, if the robust pattern of anticorrelated activity between the default and dorsal attention networks is preserved into older adulthood.…”
