Stable White Matter Structure in the First Three Years after Psychosis Onset

This study examines white matter changes in schizophrenia patients over two to three years post-onset and finds no longitudinal differences but links white matter alterations to negative symptoms.

Neurite Density and Free Water in the Gray and White Matter of Early Psychosis Patients

The paper applies the NODDI model to early psychosis patients and healthy controls to assess microstructural changes in grey and white matter, finding increased free water in grey matter not fully explained by partial volume effects.

Cortical Network Disruption is Minimal in Early Stages of Psychosis

The paper investigates white matter and cortical network changes in early psychosis and finds minimal disruption in first-episode psychosis compared to chronic patients and controls.

Astroglial Hmgb1 regulates postnatal astrocyte morphogenesis and cerebrovascular maturation.

This study identifies Hmgb1 in astrocytes as critical for postnatal astrocyte morphogenesis and cerebrovascular maturation, affecting endothelial ultrastructure and neurovascular coupling in adult mice.

An automated BIDS-App for brain segmentation of human fetal functional MRI data

The paper introduces funcmasker-flex, a BIDS App using a 3D U-net to automate fetal fMRI brain segmentation, achieving high Dice scores and reducing manual effort.
