The mind emerges from signals propagating through a physically wired network of specialised, cooperating brain regions.
activity spreads along connectome edges
BOLD-like signal ~ integrated firing
- Brain regions — major functional regions modelled as network nodes (visual cortex, PFC, hippocampus...).
- Connectome density — how richly interconnected regions are, based on real white-matter tract density.
- Stimulus input rate — how often a sensory/cognitive stimulus is injected into the network.
- Excitability threshold — activation level a region needs before it fires and passes the signal on.
This is exactly the model fMRI connectome researchers build — the same node-and-edge structure, just visualised in real time instead of a static heat-map.
