Nipoppy standardizes neuroimaging data workflows to enable reproducible and comparable multi-center data sharing.

Predicting stress response trajectories: Differential contributions of limbic and prefrontal regions to cortisol and affective responses

This study identifies distinct stress response trajectories in humans by analyzing brain region predictors of cortisol and affective responses to psychosocial stress.

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.

Executive control in Obsessive-Compulsive Disorder: A worldwide mega-analysis of task-based functional neuroimaging data of the ENIGMA-OCD consortium

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.
