In this study, we investigated the feasibility of integrating simultaneous fMRI and functional PET to uncover metabolic and hemodynamic changes linked with arousal. Our findings suggested that this multi-modal toolset can reliably detect brain-wide hemodynamic and metabolic changes spanning “alert”, “drowsy” and “sleep” conditions, therefore holding great promise in disentangling arousal-induced neuronal and vascular dynamics in future investigations.
