GWM-HFN, a Gray-White Matter heterogeneous fusion network for functional connectomes
This AI analysis synthesizes groundbreaking research into actionable intelligence for enterprise decision-makers. Explore key findings, evaluate ROI, and strategize implementation to transform your operations.
Executive Impact Summary
This research introduces and validates GWM-HFN, a novel framework for analyzing functional connectomes by integrating both gray matter (GM) and white matter (WM) BOLD signals. Unlike traditional GM-centric methods, GWM-HFN defines GM-GM functional links based on the covariance of their interaction profiles with WM bundles. This approach provides a more holistic view of brain functional architecture. The study demonstrates GWM-HFN's robust test-retest reliability, distinct topological features (enhanced modularity, reduced global integration), and unique sensitivity to individual differences. It reveals age-related linear declines and non-linear patterns, shows hyperconnectivity in autism spectrum disorder (ASD) correlating with symptom severity, and predicts individual differences in cognitive performance, particularly language tasks. GWM-HFN offers a promising avenue for developing neuroimaging biomarkers for aging and neuropsychiatric disorders by capturing WM-mediated neural communication.

The GWM-HFN framework computes GM-GM functional links by correlating the interaction profiles of GM regions with WM bundles. This offers a symmetrical 2D matrix suitable for standard graph theory, overcoming limitations of bipartite GM-WM networks and existing 3D correlation models. It was validated across six datasets.
GWM-HFN demonstrates fair short-term (~0.36 ICC) and slight-to-fair long-term (~0.20 ICC) test-retest reliability, comparable to GM-based FC. It reveals distinct topological features: enhanced modular segregation and small-worldness. Hubs are predominantly in higher-order association cortices, differing from GM-GM networks.
GWM-HFN shows significant age-related declines (linear and non-linear with peak at ~34 years). It detects GWM-HFN-specific hyperconnectivity in ASD, correlating with symptom severity and outperforming GM-GM FC. It also predicts individual cognitive differences, especially in language tasks, offering new biomarker potential.
