# Foundation Models for Brain Biomarker Discovery

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

1. **Foundation model pretraining** on large neuroimaging datasets
2. **Dynamic functional connectivity** analysis (time-varying, not static)
3. **Robust biomarker extraction** — stable across subjects and conditions
4. **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

## Activation Keywords
- brain biomarker foundation model
- dynamic functional connectivity
- neurological disorder detection AI
- robust biomarker discovery
- fMRI foundation model
- neuroimaging transfer learning
