The paper links brain structure to function by showing that commute time, derived from diffusion MRI, correlates better with functional MRI data than other measures.

The paper defines brain integration and segregation using the Ising model to analyze functional MRI data, finding that these states become less balanced with age.

The paper uses percolation theory to analyze brain development, finding that early white matter tracts become longest and densest, maintaining a giant cluster across aging and disease.

This study shows that aging reduces brain network synchrony, modeled as a critical point in communication strength, and demonstrates that metabolic changes can drive these global shifts.
