Aversive stimuliNociceptin Receptor Antagonist
What this trial is about
The study will investigate whether a nociceptin receptor antagonist will normalize neural and behavioral processes of approach/avoidance decision-making in unmedicated individuals with major depressive disorder (MDD) and anxiety disorders. More specifically, the study aims to investigate dysregulation within (1) corticostriatal-midbrain circuitry and (2) nociceptin/orphanin FQ peptide and the nociceptin receptor (NOPR).
