Small-world scale-free brain graphs from EEG
Developing individualized spatial models that capture the complex dynamics of multi-electrode EEG data is essential for accurately decoding global neural activity. A widely used approach is network mo...

Our graph models (SWSF and SWSFKron) remain robust across:
✔️ Different graph rewiring settings
✔️ Different EEG time segments
They outperform classic PLV-based graphs in all frequency bands.

These brain graphs capture consistent patterns across EEG rhythms — helping us identify individuals from their brain activity across 109 subjects.

We test our approach in two tasks:
🧠 Motor imagery (Brain-Computer Interface via EEG)
🧠 Brain fingerprinting (who is who from EEG)
Our SWSF graphs help distinguish individuals and mental tasks better than other graph models!

To make these brain networks compact but still efficient, we apply Kron reduction.
It shrinks the network while preserving important features — producing subject-specific graphs ready for learning tasks.

We turn raw EEG signals into meaningful brain networks using phase-based connectivity.
Then, we refine them to reflect small-world and scale-free properties — features observed in real brain networks. 🧠🌐
