Regions with highest Z value appearing in the contrasts healthy controls (CTR) more than vegetative state/unresponsive wakefulness syndrome patients (VS/UWS) and preserved in vegetative state/unresponsive wakefulness syndrome patients for the three cases of FDG‐PET, fMRI total neuronal and conjunction analyses of FDG‐PET and fMRI. Regions with highest Z values corresponding to a higher decrease in FDG‐PET with respect to fMRI total neuronal and with a higher decrease in fMRI total neuronal with respect to FDG‐PET (for the contrast healthy controls more than vegetative state/unresponsive wakefulness syndrome patients). Regions are shown in talaraich space
