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 identifies functional connectivity differences in OCD patients who respond versus do not respond to SSRIs, linking altered temporal-posterior networks to treatment outcomes.

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.

This study uses whole exome sequencing in families with multiple affected individuals to identify rare variants in genes associated with both Mendelian and complex neuropsychiatric syndromes.

This study determines the minimum sample size needed for multisite harmonization using structural brain MRI features and shows how sample size requirements increase with site variability.

The paper analyzes whole exome sequencing data from individuals with severe mental illness to identify genes under positive selection and their biological functions.

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.

The paper examines the relationship between adverse childhood experiences (ACEs) and the age of onset of psychiatric diagnoses in individuals from families with multiple affected members.

The paper develops a database of coding variations from the Indian population to aid in understanding genotype-phenotype correlations and disease mechanisms.
