Charting developmental trajectories of dynamic brain networks during emotional face processing

The paper uses DyNeMo to analyze MEG data from children and adults during emotional face processing, revealing distinct developmental trajectories in brain network activation and connectivity.

Decoding the neural basis of sensory phenotypes in Autism

This study identifies unique functional connectivity patterns in autism associated with five sensory processing phenotypes using machine learning.

Using deep learning to predict internalizing problems from brain structure in youth

This study uses deep learning to predict internalizing problems from brain structure in youth, finding good performance in neurodevelopmental conditions but sub-optimal in the general population.

Functional organization of multisensory integration network in children and youth with neurodevelopmental disorders predicts clinical sensory issues

The paper examines multisensory integration network (MSN) functional connectivity in neurodevelopmental disorders and finds that sensory characteristics, not diagnoses, drive the observed neural patterns.

Assigning Targetable Pathways to Transdiagnostic Subgroups Across Neurodevelopmental Disorders

The paper identifies molecular pathways associated with neurodevelopmental disorder subgroups using neuroimaging data from mice and humans.

Dataset factors associated with age-related changes in brain structure and function in neurodevelopmental conditions

The paper examines age-related changes in brain structure and function across two neurodiverse datasets, finding differences linked to demographic and clinical factors.

Genome-Wide Association Study of Obsessive-Compulsive Symptoms including 33,943 individuals from the general population

This paper conducts a GWAS of subclinical obsessive-compulsive symptoms (OCS) in 33,943 individuals, finding polygenic risk and genetic overlap with OCD.

Gene copy number variation in pediatric mental illness in a general population

The paper investigates the association between gene copy number variation and mental health traits in children, finding links to ADHD, OCD, and cognitive biomarkers.

Cortico-amygdalar connectivity and externalizing/internalizing behavior in children with neurodevelopmental disorders

The paper examines associations between externalizing/internalizing behaviors and cortico-amygdalar connectivity in children with NDDs and TDC, finding no significant linear relationships.

Integration of Brain and Behavior Measures for Identification of Data-Driven Groups Cutting Across Children with ASD, ADHD, or OCD

The paper integrates brain imaging and behavioral data to identify transdiagnostic subgroups in children with ASD, ADHD, or OCD, finding stable groups based on cortical thickness and inattention symptoms.

Shared genetic etiology between obsessive-compulsive disorder, obsessive-compulsive symptoms in the population, and insulin signaling

The paper identifies shared genetic risk factors between OCD, population-based OCS, and insulin signaling traits, suggesting a common etiological mechanism.

BOLD differences normally attributed to inhibitory control predict symptoms, not task-directed inhibitory control in ADHD

The paper investigates whether BOLD signal differences in ADHD during inhibitory control tasks reflect task-directed control or symptom management, finding correlations with symptoms rather than SSRT.

Genetic markers of ADHD-related variations in intracranial volume

The paper identifies genetic correlations between ADHD and brain volumes, finding negative associations with intracranial volume and specific brain regions.

Disrupted reinforcement learning during post-error slowing in ADHD

This study investigates reinforcement learning in ADHD using fMRI, finding altered neural correlates of error processing and dopamine regulation in ADHD compared to typically developing adolescents.

Discovery Of The First Genome-Wide Significant Risk Loci For ADHD

Genome-wide association meta-analysis of 20,183 ADHD cases and 35,191 controls finds 12 significant loci; signal concentrates in conserved regions, constrained genes, and CNS regulatory elements.

Utility of the SWAN Scale for ADHD Trait-Based Genetic Research: A Validity and Polygenic Risk Study

The paper validates the SWAN Scale as a tool for ADHD trait-based genetic research, showing it predicts ADHD diagnoses and is linked to ADHD polygenic risk.

Factor Structure and Heritability of Obsessive-Compulsive Traits in Children and Adolescents in the General Population

The paper investigates the factor structure and heritability of obsessive-compulsive traits in children and adolescents using the TOCS, identifying six dimensions and estimating heritability ranges.
