Resting State Networks' Corticotopy: The Dual Intertwined Rings Architecture

Abstract: How does the brain integrate multiple sources of information to support normal sensorimotor and cognitive functions? To investigate this question we present an overall brain architecture (called “the dual intertwined rings architecture”) that relates the functional specialization of cortical networks to their spatial distribution over the cerebral cortex (or “corticotopy”). Recent results suggest that the resting state networks (RSNs) are organized into two large families: 1) a sensorimotor family that include… Show more

“…In recent years, there have been many meta‐analyses, mega‐analyses (analyses of pooled data across many studies), and other large‐scale analyses of data within neuroimaging. In general, the aims of such analyses are to (a) test or refute findings and hypotheses (Wager, Lindquist, & Kaplan, ), (b) build a consensus around particular models, hypotheses, or theories (Salimi‐Khorshidi et al, ), (c) estimate consistency of findings (Wager, Lindquist, Nichols, Kober, & Van Snellenberg, ), (d) help define related brain regions and networks (Toro, Fox, & Paus, ; Mesmoudi et al, ), (e) interpret functional maps (Laird et al, ), or (f) segment the brain in new ways with resting‐state f MRI measurements (Yeo et al, ; Power et al, ) or using massive multimodal data (Glasser et al, ).…”

“…Local models outperform regional or more global models; however, we conjecture that randomized or multiscale models that average the predictions across spatial models could perform better. The regions that show high predictability are mostly those that show high average activation across subjects and they tend to coincide with the visualsensorimotor-auditory network described in [12], with the addition of the attentional network. Most importantly, the fact that predictability is correlated with average activation means that traditional mass-univariate random effects models used in neuroimaging studies are suboptimal, as they handle the random effects as an error term, while they actually represent more complex structures (mismatch in the coregistration, physiological variability) and may be indicative of relevant anatomical and functional differences.…”
