Beyond Monoamines: The Role of the Nociceptin/Orphanin FQ Receptor in Major Depression

The overarching goals of this research are to investigate: (1) the activity of the Nociceptin/Orphanin FQ receptor system among individuals with current or remitted MDD; (2) neural foundations of approach/avoidance behaviors in current or remitted MDDs; (3) stress-induced inflammation in individuals with remitted MDD; (4) neural markers that predict future disease course. This will be achieved through an innovative method of using functional magnetic resonance imaging (fMRI) during an approach/avoidance decision-making task, in addition to a resting positron emission tomography (PET) scan.
