We evaluated the correlations between the gray matter volume, white matter volume and age, and determined normal aging brain for his/her age in every decade. We analyzed magnetic resonance images of the brain from 828 normal Japanese subjects. Significant negative correlation between the gray matter ratio (ratio of the gray matter volume in intracranial volume) and age was shown. From these results, we determined "normal aging brain for his/her age" and "atrophied brain for his/her age in every decade.
