Journal ArticleDOI
Changing brain connectivity dynamics: From early childhood to adulthood.
TL;DR: Results showed that older participants tend to spend more time in states which reflect overall stronger connectivity patterns throughout the brain, and dynamic functional connectivity is an important factor to consider when examining brain development across childhood.
Journal ArticleDOI
Tools of the trade: estimating time-varying connectivity patterns from fMRI data.
TL;DR: This article aims to provide a gentle introduction to the application of dFC, walking readers through an openly accessible toolbox to capture dFC properties and briefly review some of the dynamic metrics calculated using this toolbox.
Journal ArticleDOI
Weighted average of shared trajectory: A new estimator for dynamic functional connectivity efficiently estimates both rapid and slow changes over time.

TL;DR: WAST enables us to detect very rapid changes in dFNC (undetected by SWPC) while MTD performance is generally lower, and provides evidence that WAST requires fewer samples (compared toSWPC) to reach a robust estimation.
Journal ArticleDOI
Multi-spatial scale dynamic interactions between functional sources reveal sex-specific changes in schizophrenia
Armin Iraji,Ashkan Faghiri,Zening Fu,Srinivas Rachakonda,Peter Kochunov,A. Belger,Judith M. Ford,Judith M. Ford,Sarah McEwen,Daniel H. Mathalon,Daniel H. Mathalon,Bryon A. Mueller,Godfrey D. Pearlson,Steven G. Potkin,Adrian Preda,Jessica A. Turner,T.G.M. van Erp,Vince D. Calhoun +17 more
TL;DR: Significant correlations between multi-spatial-scale functional interactions and symptom scores are observed, highlighting the importance of multiscale analyses to identify potential biomarkers for schizophrenia and recommending such analyses as an important option for future functional connectivity studies.
Journal ArticleDOI
A unified approach for characterizing static/dynamic connectivity frequency profiles using filter banks
Ashkan Faghiri,Armin Iraji,Eswar Damaraju,Jessica A. Turner,Vince D. Calhoun,Vince D. Calhoun +5 more
TL;DR: An approach called filter-banked connectivity (FBC) is proposed to estimate connectivity while preserving its full frequency range and subsequently examine both static and dynamic connectivity in one unified approach.
