DEPICTING ANATOMICAL DIFFERENCES IN THE BRAINS
OF NORMAL SUBJECTS
Within UCLA's Laboratory of Neuro Imaging, researchers led by Paul Thompson and Arthur Toga have created template brains that, when compared to target brains from other normal subjects, can assist in the study of anatomical brain differences related to aging and disease. The variation in color and shape of the spheres at left indicate 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.
