Image acquisition.
Image acquisition was performed with a Siemens Prisma 3T scanner (Siemens Healthcare Gmbh), using a 64-channel head coil. Functional, blood-oxygen level-dependent (BOLD) T2*-weighted data were acquired with an echo-planar imaging (EPI) sequence (repetition time = 878 ms; echo time = 24 ms; flip angle = Ernst angle (56°); field of view = 476 × 476 mm; in plane resolution = 3 × 3 mm, slice thickness = 3 mm, parallel imaging factor = 1, simultaneous multi-slice factor = 3). For precise anatomical localization of functional effects, a high-resolution anatomical 3D T1-weighted MPRAGE scan was acquired before EPI data acquisitions (repetition time = 2,300 ms; echo time = 2.36 ms; flip angle = 8°; field of view = 288 × 288 mm; voxel resolution = 0.87 × 0.87 × 0.90 mm).Participants were equipped with MR-compatible goggles for stimulus presentation in the scanner. After the initial T1 sequence, a 12-minute resting state BOLD scan was obtained, during which participants were asked to keep their eyes open and focus on a fixation cross. They then performed tasks in a counterbalanced order. The order was the same on both sessions. The total scan time was no more than 90 minutes.
