Absolute value of Spearman correlation for ROI volumes vs age derived from in vivo MRI scans: (A) Ageing HCP dataset (image resolution: .8mm isotropic; age range: 36–90 years; mean age: 59.6 years); please see main text for meaning of markers (letters). (B) OpenBHB dataset [4], restricted to subjects with ages over 35 years to match Ageing HCP (resolution 1 mm isotropic; age range: 36–86 years; mean age: 57.9 years). (C) Full OpenBHB dataset (age range: 6–86 years, mean age: 25.2 years); please note the different scale of the colour bar. The ROI volumes are corrected by intracranial volume (by division) and sex (by regression). Further slices are shown in Extended Data Fig. 6.
