Background:

Understanding the brain's default mode network (DMN) is key for cognitive science and psychiatric disorder research.
Existing DMN modeling methods have limitations in accurately capturing spatio-temporal dynamics.

Purpose of the Study:

To develop a novel methodology for comprehensive four-dimensional resting-state functional magnetic resonance imaging (4D Rs-fMRI) based default mode network (DMN) modeling.
To accurately reveal the personalized spatio-temporal patterns of the DMN.

Main Methods:

Proposed a Spatio-Temporal Brain Attention Skip Network (STBAS-Net) integrating spatial and temporal components.
Utilized multi-head attention skip connections for detailed spatial feature extraction.
Fused spatio-temporal information for overall pattern characterization and mutual constraint.

Main Results:

STBAS-Net demonstrated superior accuracy in modeling personalized DMN spatio-temporal patterns compared to existing methods.
The network successfully identified abnormal spatio-temporal patterns in patients with early Mild Cognitive Impairment (EMCI).

Conclusions:

STBAS-Net offers a potential tool for revealing human brain DMN spatio-temporal patterns.
This methodology provides a framework for exploring abnormal brain network patterns and modeling other functional networks.
