FIGURE 3. From: Brain Aging and Its Modifiers.

Comparison of regional T2* values between normotensive and hypertensive demographically adults. Vertical bars correspond to standard errors of the mean. Solid circles are normotensive and empty circles are hypertensive participants.

FIGURE 2. From: Brain Aging and Its Modifiers.

Regional T2* values as a function of age in four cortical regions. Note significant age-dependent shortening of T2* (corresponding to prolongation of relaxation rate) in prefrontal cortex (SFG) and hippocampus (HC). In contrast, susceptibility dependent relaxation rate in the primary visual cortex is unrelated to age. Correlations with age were significantly stronger for HC and SFG than for EC and VC.

FIGURE 1. From: Brain Aging and Its Modifiers.

Summary of 5-year changes in cortical regions (based on Raz et al., 2005). The effects size (Cohen's d) is the difference between the baseline and 5-year follow-up measures in standard deviation units. PFC = lateral prefrontal cortex; HC = hippocampus; IPL = inferior parietal lobule; OFC = orbitofrontal cortex; IT = inferior temporal cortex; FG = fusiform gyrus; EC = entorhinal cortex; VC = primary visual cortex. The bars indicate 95% confidence limits of d. Lack of overlap between the confidence limits indicated by the bars is tantamount to statistically significant difference at P < 0.05, two-tailed.
