Multi-Scale Structural MRI Features Reveal Task-Based Functional Connectivity and Its Alterations in Psychiatric Disorders: A Collaborative Graph Attention Network Approach
The Collaborative Graph Attention Multi-Task Network (CoGA-MTN), a deep learning framework that integrates multi-scale structural features to jointly predict task-based functional connectivity (FC) and identify potential disease-related network alterations, is introduced.
Major Depressive Disorder (MDD) is a complex psychiatric illness characterized by distributed brain network alterations. Resting-state functional Magnetic Resonance Imaging (fMRI) offers a non-invasive probe of these functional disruptions, but its high-dimensional and subtle patterns necessitate computational decoding...

BACKGROUND
Major depressive disorder (MDD) is a highly heterogeneous affective disorder, and the identification of reliable neuroimaging markers remains challenging. Resting-state functional magnetic resonance imaging offers a promising approach for characterizing altered brain functional organization in MDD. However,...

Autism spectrum disorder (ASD) is a neurodevelopmental condition characterized by atypical large-scale brain network organization. Using the comprehensive Autism Brain Imaging Data Exchange (ABIDE-I and ABIDE-II; n = 2013 participants), this study systematically evaluated three representative graph neural network (GNN)...
