^*Anatomical labels were assigned by imposing each peak on two probabilistic atlases, the Harvard-Oxford Cortical and Subcortical Structural Atlases in the FSL analysis package. For the cerebellum, labels were assigned following visual inspection. Cluster units are number of voxels in MNI space.

TBI, traumatic brain injury; NC, normal comparisons; FPN, fronto-parietal network; ECN, executive control network; SMN, somato-motor network; DMN, default mode network; MNI, Montreal Neurological Institute.
