White Matter Tracts

Age related changes in white matter density in the internal capsule. The maps of t-statistic values are superimposed on axial sections through the magnetic resonance (MR) image of a single subject. The images depict the exact locations in the internal capsule (indicated by the arrow) that showed statistically significant correlations between white matter density and the subject's age.
