Fig. 1: Age and average controllability measures for all n = 93 participants.

a Chronological age, predicted brain age, and brain age gap. b Average controllability for the inferior frontal gyrus (IFG) pars opercularis, posterior superior temporal gyrus (posterior STG), and the pole of the superior temporal gyrus (pole STG). The y-axis in panel (b) was capped at 5 for visualization purposes. Explanation of boxplots: The box represents the interquartile range (first to third quartile), the horizontal line in the box represents the median, and the vertical lines outside the box (whiskers) represent data points outside the interquartile range.
