Human Brain Atlases across the lifespan – Anatomical Segmentations

Abstract

Dickie and colleagues generated seven age-specific brain tissue sets/atlases of T1-weighted brain MRI illustrative of the adult lifespan from 25 to 92 years, which are representative of the atrophy and neurovascular health characteristics of normal individuals in seven age-bands: 1) 25-34 years, 2) 35-44 years, 3) 45-54 years, 4) 55-64 years, 5) 71-74 years, 6) 75-78 years, and 7) 91-93 years. These atlases can be downloaded from Edinburgh Datashare at https://doi.org/10.7488/ds/1369. The present dataset contains the anatomical segmentations of the average T1-weighted brain template from each of these sets, with the exception of the cortical segments, obtained using freesurfer 6.0 (https://surfer.nmr.mgh.harvard.edu/). It also contains the scripts used to generate the nifti-1-formatted files of this dataset, written as Linux shell and Matlab scripts.
