Structurally-Constrained Relationships between Cognitive States in the Human Brain

Abstract: The anatomical connectivity of the human brain supports diverse patterns of correlated neural activity that are thought to underlie cognitive function. In a manner sensitive to underlying structural brain architecture, we examine the extent to which such patterns of correlated activity systematically vary across cognitive states. Anatomical white matter connectivity is compared with functional correlations in neural activity measured via blood oxygen level dependent (BOLD) signals. Functional connectivity is s… Show more

“…Following prior work (Bassett, Brown, Deshpande, Carlson, & Grafton, 2011; Gu et al, 2015; Hermundstad et al, 2013; Hermundstad et al, 2014), we connected nodes (brain regions) by the number of white matter streamlines identified by a commonly used deterministic tractography algorithm (Cieslak & Grafton, 2014). This procedure results in sparse, weighted, undirected structural brain networks for each participant.…”

“…(68)). Although the effects of task-related manipulations and spontaneous changes in connectivity during resting state may be different, the idea that functional connectivity can occupy different, context-dependent states is common to both.…”

“…In this case, the network nodes still represent brain regions or voxels, but the network edges now represent the estimated strength of white matter tracts linking pairs of nodes [51,52]. These so-called ’structural brain networks’ then represent the pattern of white matter microstructure supporting both baseline function [51,53,54] and its adaptability in response to task demands [55]. …”
