Trend analysis of the CB and frontal UF. Trend lines for both linear (solid) and quadratic (dashed) trends are represented over the y-axis component (Talairach coordinates) of each tract using the effect size (partial eta) based on a pairwise analysis at points along a tract. F statistics for best fit for both linear and quadratic terms are displayed below the data. Linear trends are significant for the left and right CB, and the left and right (frontal) UF. The vertical dashed line approximates the border between frontal and parietal cortex, according to the anterior border precentral sulcus. CB = cingulum bundle; UF = uncinate fasciculus; YA = young adult; OA = older adult.
