All scans were performed using a Siemens 3 T Prisma Magnetom VD13 echo speed scanner with a 20-channel head coil located at the Wohl Institute for Advanced Imaging at the Tel-Aviv Sourasky Medical Center. Structural scans included a T1-weighted 3D axial spoiled gradient echo (SPGR) pulse sequence (repetition time/echo time [TR/TE] = 1860/2.74 ms, flip angle = 8°, voxel size = 1 × 1 × 1 mm, field of view = 256 × 256 mm, slice thickness = 1 mm).
Functional whole-brain scans of all fMRI tasks were performed in an interleaved bottom-to-top order with a T2*-weighted gradient echo planar imaging pulse sequence (TR/TE = 2500/30 ms, flip angle = 82°, voxel size = 2.3 × 2.3 × 3 mm, the field of view = 220 × 220 mm, slice thickness = 3 mm, 42 slices per volume). For three participants in the social feedback task and the guided self-evaluation task, the TE was 35, flip angle was 90° and 38 slices per volume were obtained. These participants were included in the analysis. The number of volumes acquired for each of the fMRI tasks was as follows: social feedback—246; guided self-evaluation—2 sessions including 118 volumes each; reward—2 sessions including 117 volumes each.
