The paper creates lifespan reference curves for white matter microstructure using diffusion MRI data from multiple datasets and validates them with ApoE4 risk factor analysis.

The paper identifies differentially expressed genes in PTSD and MDD across brain regions, highlighting shared and unique transcriptional patterns and immune-related pathways.

This study identifies transcriptomic changes and genetic factors associated with PTSD using postmortem brain tissue and GWAS data, revealing sex differences and divergence from MDD.

The paper identifies smaller brain volumes in the right dorsolateral prefrontal cortex and insula as predispositional risk factors for alcohol use, supported by genetic and longitudinal evidence.

The paper examines how subtle variations in caregiving, specifically familial affective responsiveness, influence amygdala reactivity to interpersonal threat in adolescents, revealing paradoxical associations with stress levels.

The paper identifies two trajectories of alcohol use initiation in adolescents and links early initiation to increased risk of AUD, stress, and amygdala reactivity.

The paper evaluates 15 candidate SNPs associated with psychiatric disorders using 6,165 diffusion MRI scans, finding no significant associations after correction for multiple testing.
