Microbes on the Mind: Multi-modal Neuroimaging Reveals Gut-Brain Axes in Infants

This study links gut microbiome features to brain development in infants using multimodal neuroimaging and metagenomics.

UltimateSynth: MRI Physics for Pan-Contrast AI

UltimateSynth synthesizes realistic MRI images across diverse contrasts to train AI models that generalize across scanner types, sequences, and age groups, achieving robust tissue segmentation with low variability.

The Growing Little Brain: Cerebellar Functional Development from Cradle to School

This study maps cerebellocortical functional connectivity in children from birth to 60 months, revealing hierarchical organization and age-related changes in cerebellar network gradients.

Functional Hierarchy of the Human Neocortex from Cradle to Grave

This study maps the developmental trajectories of three functional connectivity gradients in the human neocortex across the lifespan using functional MRI data.

Multifaceted Atlases of the Human Brain in its Infancy

This paper introduces month-specific brain atlases for infants aged two weeks to two years, integrating surface and volumetric data to capture early brain development in a unified coordinate system.

Brain-wide functional networks associated with anatomically- and functionally-defined hippocampal subfields using ultrahigh-resolution fMRI

This study uses ultrahigh-resolution fMRI to compare anatomically and functionally defined hippocampal subfields and their brain-wide functional connectivity.
