Dissociable Neural Responses to Conditioned Social Threats are Modulated by Spatial Proximity in PTSD and MDD

In 50 trauma-exposed veterans, thalamic hypoactivity to near virtual-reality threats tracked both PTSD and MDD severity, while amygdala hyperactivity to far threats tracked only PTSD severity.

Image-Based Meta- and Mega-Analysis (IBMMA): A Unified Framework for Large-Scale, Multi-Site, Neuroimaging Data Analysis

IBMMA improves neuroimaging analysis by handling missing data and large datasets, revealing new brain region findings overlooked by traditional methods.

Volumetric Differences of Thalamic Nuclei are Associated with Post-Trauma Psychopathology

The paper examines thalamic volume differences in trauma-exposed individuals with PTSD, MDD, and controls, finding specific volume reductions and associations with symptom severity and childhood trauma.

Genomic Structural Equation Modeling Reveals Latent Phenotypes in the Human Cortex with Distinct Genetic Architecture

The paper uses genomic structural equation modeling to identify latent genetic factors underlying cortical surface area and thickness, finding genetic correlations with psychiatric disorders.

The Genetic Architecture of Amygdala Nuclei

This study identifies genetic loci associated with amygdala nuclei volumes using UK Biobank data, finding both unique and shared genetic architectures and immune-related pathways.

Bridging Big Data: Procedures for Combining Non-equivalent Cognitive Measures from the ENIGMA Consortium

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

A Comparison of Methods to Harmonize Cortical Thickness Measurements Across Scanners and Sites

This paper compares four methods for harmonizing cortical thickness data across multiple sites and finds that ComBat-GAM is most effective in detecting case-control differences and age-related cortical thinning.

ENIGMA HALFpipe: Interactive, reproducible, and efficient analysis for resting-state and task-based fMRI data

HALFpipe provides a reproducible, interactive, and efficient analysis pipeline for fMRI data, supporting preprocessing, post-processing, and quality assessment.

Alcohol Use Disrupts Age-Appropriate Cortical Thinning in Adolescence: A Data Driven Approach

This study uses a data-driven method to show that alcohol use in adolescents affects cortical thinning differently across age groups.

Threat-Induced Anxiety During Goal Pursuit Disrupts Amygdala-Prefrontal Cortex Connectivity in Posttraumatic Stress Disorder

This study examines how threat during goal pursuit affects amygdala-prefrontal cortex connectivity in PTSD, finding disrupted connectivity and altered vmPFC activation in PTSD patients compared to trauma-exposed controls.

Adaptive Identification of Cortical and Subcortical Imaging Markers of Early Life Stress and Posttraumatic Stress Disorder

This study uses a machine learning method to identify neuroimaging markers of PTSD and ELS in veterans, finding that combinatorial features improve classification accuracy.

Resting-State Brain Fluctuation and Functional Connectivity Dissociate Moral Injury from Posttraumatic Stress Disorder

The paper investigates neural differences between moral injury and PTSD using resting-state fMRI, finding distinct associations with brain fluctuations and functional connectivity.

Economic status mediates the relationship between educational attainment and posttraumatic stress disorder: a multivariable Mendelian randomization study

This study uses genetic data to show that educational attainment causally reduces PTSD risk, with economic status mediating this relationship.

Genome wide association study of hippocampal subfield volume in PTSD cases and trauma-exposed controls

The paper conducts a GWAS of hippocampal subfield volumes in PTSD cases and trauma-exposed controls, identifying genetic associations and gene-environment interactions.

Smaller Hippocampal CA-1 Subfield Volume in Posttraumatic Stress Disorder

This study finds smaller left hippocampal CA1 volume in PTSD patients compared to trauma-exposed controls, with associations dependent on covariates.
