MRI acquisition and pre-processing
For TBI-D subjects, a 3 T Siemens Magnetom Prisma magnetic resonance scanner was used to acquire 16.5 min of resting-state blood oxygen-level dependent (BOLD) data in three runs. The baseline MRI scan was acquired at least one day before treatment to provide time for preprocessing and target selection. The post-treatment MRI scan was acquired at least one day after the conclusion of treatment to avoid bias from acute effects of treatment. For HCP subjects, a 3 T Siemens Connectome Skyra was used to acquire 58 min of resting-state BOLD data in four runs. Preprocessing was conducted using in-house scripts described in Power et al.
