Template brain used to compare with target brains from subjects
This template brain is used in studies on the anatomical differences in brains related to aging and disease. The variation in color and shape of the spheres at left indicates the magnitude and principal directions of the anatomical differences across subjects. In this model, the greatest difference is in the parietal lobe (lower right), an anticipated result since this lobe appeared much later in the evolutionary process than did more primitive brain areas that vary little from brain to brain.
