Dynamic Reorganization of the Frontal Parietal Network During Cognitive Control and Episodic Memory

Abstract: Higher cognitive functioning is supported by adaptive reconfiguration of large-scale functional brain networks. Cognitive control (CC), which plays a vital role in flexibly guiding cognition and behavior in accordance with our goals, supports a range of executive functions via distributed brain networks. These networks process information dynamically and can be represented as functional connectivity changes between network elements.Using graph theory, we explored context-dependent network reorganization in 56 … Show more

“…The increased connectivity within DAN may indicate outward attention (Hopfinger, Buonocore, & Mangun, 2000), and the enhanced coupling between FPN and DAN as well as the Core subsystem of DMN may support the sustained attention focus on external stimuli. The cognitive control processing can be implemented by enhancing functional connectivity within networks and between networks (Ray et al, 2020). Previous research has suggested that brain connectivity within networks is related to a specific cognitive process, whereas the connectivity between networks is essential for effectively communicating and integrating information of various cognitive processes (Warren et al, 2014).…”

“…In our study, the 'feature' that repeated was the stimulus identity itself, but the interactive role of attention with memory mechanisms is a known property of memorial processing. During memory processing, attention appears to exert substantial network effects (Ray et al, 2020), and appears to amplify priming effects in the parietal cortex. Effects related to attentional shifts may also explain the observed peaks in the thalamus, the principal sensorial gateway to the cortex (Barron, Eickhoff, Clos, & Fox, 2015;Saalmann & Kastner, 2011).…”

“…The suppression of DMN is critical for goal-directed cognitive processes (Spreng, Stevens, Chamberlain, Gilmore, & Schacter, 2010). Cooperation among these top-down control systems of the brain is necessary for controlling attention, working memory, decision making, and other high-level cognitive operations (Hellyer et al, 2014; Keller et al, 2015; Raichle, 2015; Ray et al, 2019; Spreng, 2012; Vincent, Kahn, Snyder, Raichle, & Buckner, 2008).…”
