This study examines the relationship between effortful control and cortical brain structure in 5-year-olds using the FinnBrain cohort, finding specific brain regions associated with EC subscales.

The paper links early language development trajectories to gray matter density in the right superior frontal gyrus at age five using longitudinal data from the FinnBrain Birth Cohort Study.

This study uses functional connectome harmonics to analyze neonatal brain gradients and finds that power and energy metrics differ between term and preterm neonates, predicting postmenstrual age.

The paper applies Functional Connectome Harmonics and Leading Eigenvector Dynamics Analysis to resting-state fMRI data from children to characterize preadolescent brain network organization.

This study examines how maternal psychological distress before and after birth relates to brain structure in 5-year-olds, finding both positive and negative associations with gray matter volumes in different brain regions.

skiftiTools enables statistical analysis and visualization of TBSS-derived diffusion MRI data using R, supporting advanced modeling and data manipulation.

This study examines the structural brain correlates of speech disfluency in 5-year-olds, finding associations between grey matter volume and disfluency without significant sex differences.

The paper links neonatal white matter microstructure to attention disengagement from fearful faces in infants using diffusion MRI and eye tracking.

This study finds a positive association between maternal pre-pregnancy BMI and infant left caudate nucleus mean diffusivity, suggesting in utero exposure to maternal adiposity may impact brain development.

This study examines the relationship between neonatal amygdala microstructure and attention to emotional faces, finding a negative association between amygdala mean diffusivity and disengagement from fearful faces.

The paper introduces a multi-contrast neonatal brain template and atlases to improve image processing and spatial normalization in neonatal neuroimaging.

The paper evaluates the effect of diffusion encoding directions on DTI scalar estimates in neonates using TBSS analysis and finds negligible differences with 24 or more directions.

The paper uses tract-based spatial statistics to examine sex differences, lateralization, and age-related white matter development in infants and 5-year-olds using diffusion tensor imaging.

This paper evaluates the feasibility of using FreeSurfer for processing T1-weighted brain images of 5-year-olds, showing minor effects of manual edits and recommending quality assessment for reliable segmentation.

This study compares FSL-FIRST and FreeSurfer automated subcortical segmentation tools against manual segmentation in 5-year-olds, finding FSL-FIRST more accurate for most structures but with overestimation issues for small ones.

This study compares diffusion MRI metrics in simulated edema and fiber crossing, finding DBSI provides more accurate diffusivity and angle estimates than DTI and other methods.
