Beyond Monoamines: The Role of the Nociceptin/Orphanin FQ Receptor in Major Depression
This study looks at the role of the Nociceptin/Orphanin FQ receptor system in the brain of individuals with current or past major depressive disorder (MDD). It also examines how individuals with a history of depression make certain decisions and which brain regions are involved in such decisions. Information collected through MRI, PET, biospecimens (i.e., blood, saliva) and behavioral tasks will be used to predict depressive symptoms in the future.
