This study analyzes fMRI data from OCD patients and controls to identify age-specific differences in brain activation during inhibitory control and error processing.

The paper examines the relationship between white matter microstructure, measured by fractional anisotropy, and transition to psychosis in individuals at clinical high risk, finding directionally consistent but small associations.

This study shows that adolescent NMDAR hypofunction impairs short-term memory by weakening thalamofrontal synapses, not through interneuron dysfunction.

The paper examines longitudinal white matter changes in early psychosis using diffusion tensor imaging and finds no significant group differences or associations with symptom progression, but links antipsychotic medication dose to lower fractional anisotropy.

This paper introduces a Hodge-Laplacian framework to analyze higher-order topology in OCD brain networks, identifying loop-level abnormalities not detectable by conventional functional connectivity analysis.

This study analyzes fMRI data from OCD patients and controls to identify neural activation patterns during executive control tasks, finding reduced activation in frontoparietal regions and increased default mode network activity in OCD.

The paper examines hippocampal and amygdala subfield volumes in OCD patients and healthy controls, finding differences based on medication status.

This study examines brain morphometric deviations in individuals at clinical high-risk for psychosis and finds they largely overlap with healthy variation and are not strongly associated with symptom severity or conversion to psychosis.

The paper demonstrates a data harmonization process for memory testing across 53 studies, reducing inter-site variance while preserving covariate effects.

This study identifies white matter microstructural alterations in adult OCD patients and links them to clinical features, while finding no such abnormalities in pediatric patients.
