Study #2: Research on dopamine, emotions, and the brain

Are you feeling sad, blue, or down? Have you lost interest in activities you normally enjoy?


MGH and McLean Psychiatry researchers seek volunteers to understand the role of dopamine, a chemical that is naturally released by brain cells, in emotions and behavior. The study includes three sessions, including a PET scan (Positron Emission Tomography) and a fMRI scan (functional Magnetic Resonance Imaging).



You may be eligibile to participate if you:


  • are between the ages 18-45 years

  • are currently feeling depressed or down

  • have no past psychiatric or neurological illness other than depression

  • are not currently taking psychiatric medications




If eligible to participate, you can receive up to $380. Reimbursement for travel is also available.
