The influence of head motion on intrinsic functional connectivity MRI.
TL;DR: Head motion was associated with decreased functional coupling in the default and frontoparietal control networks--two networks characterized by coupling among distributed regions of association cortex and other network measures increased with motion including estimates of local functional coupling and coupling between left and right motor regions.

Intrinsic Functional Connectivity As a Tool For Human Connectomics: Theory, Properties, and Optimization
Koene R. A. Van Dijk,Trey Hedden,Archana Venkataraman,Karleyton C. Evans,Sara W. Lazar,Randy L. Buckner +5 more
TL;DR: The brevity and robustness of fcMRI positions it as a powerful tool for large-scale explorations of genetic influences on brain architecture and how it can be combined with HARDI techniques to support the emerging field of human connectomics.

Parallel distributed networks resolved at high resolution reveal close juxtaposition of distinct regions
Rodrigo M. Braga,Rodrigo M. Braga,Koene R. A. Van Dijk,Jonathan R. Polimeni,Jonathan R. Polimeni,Mark C. Eldaief,Randy L. Buckner +6 more
TL;DR: Fine spatial details and juxtapositions of the two networks can be identified within individuals at high resolution, providing insight into the network organization of association cortex and placing further constraints on interpretation of group-averaged neuroimaging data.
