All scans were conducted at the Wayne State University MR Research Facility at Harper University Hospital (Detroit, MI), with a 3-T Siemens Magnetom Verio scanner using a 32-channel Head Matrix coil. T1-weighted whole-brain anatomy images were acquired using a magnetization-prepared rapid gradient-echo sequence. Children, adolescents, and young adults: 192 sagittal slices, repetition time (TR) = 2200 ms, echo time (TE) = 4.26 ms, flip angle (FA) = 9°, field of view (FOV) = 256 mm, 192 × 256 voxels, and voxel size = 1 mm × 0.5 mm × 1 mm. Older adults: 176 slices, TR = 1680 ms, TE = 3.51 ms, FA = 9°, FOV = 256 mm, voxel size = 0.7 mm × 0.7 mm × 1.3 mm).
Functional images were acquired using a T2*-weighted gradient-echo sequence (Children, adolescents, and young adults: 30 slices parallel to the AC–PC plane, TR = 2000 ms, TE = 30 ms, FA = 90°, voxel size = 3.1 mm × 3.1 mm × 4 mm; older adults: 37 slices parallel to the AC-PC plane, TR = 2200 ms, TE = 30 ms, FA = 80°, FOV = 220 mm, voxel size = 2.8 mm × 2.8 mm × 2.8 mm). For children, adolescents, and young adults, the encoding task was completed in three consecutive functional runs of 118 volumes, encoding 40 scenes in each, or 120 scenes in total. For older adults, the task was completed in one functional run of 276 volumes, encoding 80 scenes in total.
