This study evaluated the effect of anesthesia on functional and metabolic brain connectivity, measured with simultaneous PET/MR using an awake monkey model. Results show a profound disruption of functional connectivity, effective connectivity, and novel approaches to metabolic connectivity following the administration of IV ketamine.
