Further study details as provided by Affective Neuroscience Laboratory:

Primary Outcome Measures:

Whether an acute dose of bupropion vs. placebo differentially affects the neurobiology and behavior of reward processing in depressed participants. [ Time Frame: 1 day ] [ Designated as safety issue: Yes ]

Enrollment:	32
Study Start Date:	April 2005
Study Completion Date:	July 2007

Arms	Assigned Interventions
Placebo: Placebo Comparator	Drug: Placebo Administered 5 hours prior to fMRI scanning (randomly assigned, double blind)
Bupropion: Active Comparator	Drug: Bupropion 150 mg of bupropion administered 5 hours before fMRI scanning

Detailed Description:

A cardinal feature of Major Depressive Disorder is anhedonia, which is a lack of pleasure in normally enjoyable activities. In order to understand reward processing in depressed individuals it is also necessary to study reward processing in people who are not depressed. Bupropion, the active drug in the anti-depressant Wellbutrin XL, has been shown to increase brain reward functioning in animals. The goal of the present study is to investigate the effects of Wellbutrin XL administered to psychiatrically healthy individuals as they perform a computer task known to assess reward processing.
