JHU ICBM labels 2mm Atlas

Overview

The JHU ICBM labels 2 mm brain atlas is a probabilistic, population-based parcellation of major white matter tracts and selected gray matter regions, derived from diffusion-weighted and structural MRI data from healthy adults in the International Consortium for Brain Mapping; it segments the brain into anatomically defined regions such as the corpus callosum subdivisions, internal and external capsules, corona radiata, association fiber bundles, and key subcortical structures, with labels registered to ICBM/MNI space at 2 mm isotropic resolution. Construction involved manual and semi-automated delineation of tracts using diffusion tensor tractography and anatomical landmarks, followed by normalization and averaging across subjects to yield probabilistic maps and discrete label images. The atlas is widely used in neuroimaging for voxel-based analyses, region-of-interest studies, tract-based spatial statistics, and anatomical localization in both research and clinical contexts, facilitating standardized reporting and comparison of structural findings across studies.
