Figure 1: — A. IVIM parameters, $D *$ , $D$ , and $f$ in older adults (first column), in young adults with normal sleep (middle column), and the same young adults with sleep deprivation (third column) in the SAS. B. $D *$ values in all three groups: young adults after a night of normal sleep (blue), young adults after 24 hours of sleep deprivation (yellow), and older adults after normal sleep (red). C. Only $D *$ was significantly different (p=0.009) after 24 hours of sleep deprivation compared to a night of normal sleep. D, E. $D$ , and $f$ values in all three groups: young adults after a night of normal sleep (blue), young adults after 24 hours of sleep deprivation (yellow), and older adults after normal sleep (red). No difference was observed with aging. Supplementary figure 1 shows the ROIs generated for this study.
