Area of Science:

Neuroscience
Network Science
Statistical Modeling

Background:

Brain networks are analyzed at various scales, but current methods often use only single-scale information.
This limitation hinders comprehensive understanding of brain-phenotype relationships.

Purpose of the Study:

To introduce Multi-Scale Network Regression (MSNR), a novel penalized multivariate approach.
To model brain networks by integrating both edge- and community-level information.

Main Methods:

MSNR assumes a low rank and sparse structure for less complex and more interpretable models.
The method was applied to a large neuroimaging cohort (n = 1,051).

Main Results:

MSNR identified interpretable and significant connectivity patterns related to brain development, sex differences, and motion artifacts.
The method balanced prediction performance and model complexity, offering improved interpretability over single-scale approaches.

Conclusions:

MSNR effectively integrates multi-scale network information for robust brain-phenotype analysis.
This approach holds potential for novel insights into brain-behavior relationships.
