Overview

The HarvardOxford cortical maximum-probability threshold-25% 2 mm brain atlas is a probabilistic anatomical parcellation of the human cerebral cortex derived from structural MRI scans of healthy adult volunteers, created by manual expert labeling and voxel-wise probability mapping of cortical regions in standard MNI152 space and then converted into a discrete “maxprob” atlas by assigning each voxel to the cortical label with the highest probability, conditional on that probability exceeding a 25% threshold; it provides a set of macroscopic cortical regions (e.g., frontal, parietal, temporal, and occipital areas, including gyri- and sulci-based labels) sampled at 2 mm isotropic resolution. Biologically and neuroscientifically, it is used to define standardized cortical regions of interest in structural and functional neuroimaging, to support group-level analyses, lateralization studies, lesion mapping, and connectivity research, and to facilitate reproducible cross-study comparisons in fMRI, diffusion MRI, and lesion-symptom studies.
