Regional amplitude of rsfMRI BOLD signal after mTBI was quantified using amplitude of low-frequency fluctuation (ALFF). The significant increase of ALFF around the impact regions at 24 h and renormalized at 50 days after mTBI may suggest the dynamics of neuronal activity and neurovascular response induced by the injury.
