FIGURE 2. Correlations between age and rCBF in different postures in cerebellum (supine, r = 0.13; sitting, r = 0.26; standing, r = 0.43) and upper frontal area (supine, r = 0.25; sitting, r = 0.23; standing, r = 0.55). Absolute levels of upper frontal rCBF in standing position tended to decrease with age. CBF = cerebral blood flow; with dashed line = supine; with dotted line = sitting; with solid line = standing.
