Global topology of brain-wide co-fluctuations links task states, personality, and behavioral symptom dimensions

The paper uses topological analysis of fMRI dynamics to show that pairwise co-fluctuations better capture task states and link to personality and symptom dimensions than other interaction representations.

Refining RDoC Using Individual-Level Task fMRI Factor Models RevealsReproducible and Clinically Relevant Brain-Wide Motifs

This paper validates data-driven factor models over RDoC-based models using fMRI and behavioral data, showing better reproducibility and clinical relevance across neural and behavioral domains.
