Relationship between subject age and a. Right hippocampal volume, b. Right inferior longitudinal fasciculus (ILF) fractional anisotropy (FA), c*. maximum node degree of density network derived using the hcp-mmp atlas, d*. Within-network average functional connectivity (FC) derived using the Yeo17 atlas, e. Functional gradient distance for visual resting state network derived from the Yeo17 atlas, and f. Peak frequency in the alpha band derived from magnetometer (squares) and gradiometers (circles) from MEG data. These analyses include subjects from the PING (purple), HCP1200 (green), and Cam-CAN (yellow) datasets. Linear regressions were fit to each dataset, and a quadratic regression was fit to the entire dataset (blue). * All points in c, and d are presented.
