Charting Cervical Spinal Cord Morphometry Across the Lifespan

The paper generates lifespan normative charts for cervical spinal cord morphometry using MRI data, revealing non-linear changes and sex differences across ages 0-100.

Automated Segmentation and Tractography of Brainstem and Subcortical White Matter

The paper develops an automated pipeline for segmenting and parcellating brainstem and subcortical white matter pathways using diffusion MRI data.

Lifespan Trajectories of Asymmetry in White Matter Tracts

This study characterizes white matter asymmetry across the lifespan using a large dataset, revealing dynamic changes in asymmetry patterns with age.

White matter microstructure and macrostructure brain charts across the human lifespan

The paper develops normative reference charts for white matter microstructure and macrostructure across the lifespan using diffusion MRI data from 50 studies.

Analytic Bounds on GAMLSS Model Variability of Normative White Matter Brain Charts

The paper evaluates the variability of GAMLSS-based brain charts using analytic and empirical methods, finding low coefficient of variation across most white matter features.

Longitudinal Investigation of Neurobiological Changes Across Pregnancy

This study investigates longitudinal brain structure changes during pregnancy and finds reduced gray matter volume and increased white matter neurite density, linked to hormone levels.

Age-related change in task-evoked amygdala-prefrontal circuitry: a multiverse approach with an accelerated longitudinal cohort aged 4-22 years

This paper uses multiverse analyses on fMRI data from an accelerated longitudinal cohort to assess the robustness of age-related changes in amygdala-prefrontal circuitry to analytical choices.

Cross-sectional and longitudinal associations of family income-to-needs ratio with cortical and subcortical brain volume in adolescent boys and girls

This study examines how family income-to-needs ratio relates to brain volume changes in adolescents, finding sex differences in these associations.
