BOLD variability by age group and task condition in several ROIs. Figure shows BOLD variability transformed (except for A7r L, as indicated with “⁰”) across age groups (Younger Adults in varying shades of teal, and Older Adults in different shades of orange) and task conditions (Line 1:1, Line 3:1 and Angle 3:1) for ROIs with a significant main effect of TASK CONDITION (namely, A6dl L, A7r L and lsOccG L) or AGE GROUP x TASK CONDITION interaction (i.e., A7m R, bilateral V5/MT+, bilateral Crus I and VI R), before correcting for multiple comparisons. None of these results remained significant after correction (in all, q > 0.05). Mean BOLD SD, per group, for each task condition is indicated by an “X”. Abbreviations: A6dl = dorsolateral premotor cortex; A7m = precuneus; A7r = superior parietal lobe; Crus I = cerebellar lobule Crus I; L = Left; L = left; lsOccG = lateral superior occipital gyrus; OA = Older Adults; R = Right; V5/MT+ = motion area V5/MT+; VI = cerebellar lobule VI; YA = Younger Adults.
