  Sequence & imaging parameters 
  
  High-resolution anatomical scans were acquired using a T1-weighted (T1w) magnetization prepared rapid gradient echo 
  (MPRAGE) sequence (TR = 2500 ms, TE = 2.31 ms, T1 = 934 ms, flip angle = 7°, 0.8 mm thickness) followed by a gradient 
  echo fieldmap (TR = 758 ms; TE1 = 4.92 ms; TE2 = 7.38 ms; flip angle = 60°). A T2-weighted (T2w) turbo spin echo (TSE) 
  scan was also acquired with an oblique coronal orientation positioned orthogonally to the main axis of the hippocampus 
  (TR/TE = 9860/50 ms, flip angle = 122°, 0.4 × 0.4 mm2 in-plane resolution, 2 mm slice thickness, 38 interleaved slices 
  with no gap, total acquisition time = 5:42 min).
