From Geometry to Hierarchy: Charting the Dominant Modes of Human Cortical Function Through Development

This study shows that the development of long-range cortical connections leads to the emergence of hierarchical functional modes in the human cortex, shifting from geometrically driven patterns to sensory-association organization.

Spurious model comparisons are widespread in biomedical artificial intelligence

97% of 184 high-impact biomedical AI studies compare cross-validated models with tests assuming fold independence; in 69% of re-analyzable studies a significant comparison does not survive correction.

Test Retest Reliability of Meta Analytic Networks During Naturalistic Viewing

This study compares the test-retest reliability of functional brain networks from resting-state and naturalistic viewing paradigms across two sessions, showing increased reliability with naturalistic viewing but varying by stimuli and networks.

Rate of brain aging associates with future executive function in Asian children and older adults

This study tests a brain age model on Singaporean children and elderly, finding that brain age gap change relates to future executive function in both groups.

Homotopic local-global parcellation of the human cerebral cortex from resting-state functional connectivity

The paper develops homotopic local-global parcellations of the human cerebral cortex using resting-state and task-fMRI, showing improved homogeneity and lateralization compared to existing parcellations.

Stage dependent differential influence of metabolic and structural networks on memory across Alzheimer's disease continuum

The paper examines how structural and metabolic network integrity influences memory across Alzheimer's disease stages, finding pathology-dependent changes in these relationships.
