ADVERSE EFFECTS
MRI data were collected using a 3 T Siemens Magnetom Verio Symo MR B17 (Siemens 243 Healthineers, Erlangen, Germany) located at the Hospital Germans Trias i Pujol. Participants were asked to rest with their eyes closed during the scan session, had head motion constrained, and were offered earplugs to reduce the adverse effects of scanner noise. Resting-state functional BOLD imaging scans were obtained with a gradient echo planar imaging sequence (acquisition time 8:08 min, voxel 3.1 × 3.1 × 3.0 mm, TR/TE 2000/25 ms, flip angle 78°, slices 39, thickness 3 mm, volumes 240). We also collected T1-weighted multi-planar reformat sequences (acquisition time 5:26 min, voxel 0.9 × 0.9 × 0.9 mm, TR/TE/TI 1900/2.73/900 ms, flip angle 9°, slices 192, thickness 0.9 mm) which were used during the rs-fMRI preprocessing to co-register functional and structural MRI data. Scans were visually checked by an expert neuroradiologist.
