This paper introduces diffusion similarity networks (DSNs) using diffusion MRI to map brain structural organization, showing improved sensitivity to age, cognition, and sex compared to prior methods.

This paper maps human cerebral cortex microstructure using diffusion MRI, identifying 21 metrics linked to cytoarchitecture, function, and cognition, and showing their heritability and predictive power for age and cognition.

This study uses fMRI to show that differentiation and integration in the hippocampus and related regions work together to build environmental representations during navigation, with integration variability linked to navigation efficiency.
