Paper: Recent q-bio.NC (May 2026, Deepank Girish et al.)
Core Approach
Using foundation models pretrained on large-scale neuroimaging data to discover robust biomarkers of neurological disorders from dynamic functional connectivity patterns.
Key Components
- Foundation model pretraining on large neuroimaging datasets
- Dynamic functional connectivity analysis (time-varying, not static)
- Robust biomarker extraction — stable across subjects and conditions
- Neurological disorder classification — generalizable detection
Why Foundation Models?
- Transfer learning from large unlabeled datasets
- Capture general brain dynamics patterns
- Fine-tune efficiently for specific disorders
- Reduce need for large labeled clinical datasets
Robustness Focus
- Cross-subject generalization
- Cross-platform consistency (different scanners/protocols)
- Temporal stability of discovered biomarkers
Applications
- Parkinson's disease detection
- Alzheimer's disease biomarkers
- Epilepsy focus localization
- Depression subtype classification
