This study examines the effects of an antidepressant medication and placebo on the brain functioning of normal subjects. In this study, recordings of brain electrical activity are being used to detect and monitor the response to treatment with venlafaxine IR (Effexor), a drug used for the treatment of depression. The intent of this study is to test specific hypotheses regarding: 1. long-term brain effects of a single course of antidepressant treatment 2. pharmaco-conditioning effects underlying antidepressant tolerance/sensitization 3. brain functional response to initial versus subsequent antidepressant trials in normal healthy subjects.


Inclusion Criteria: - Subject age is 18-75 years - Subject must be in overall good health (i.e., free of any medical condition known to affect brain function). - Subject must have participated in former study, Physiologic Monitoring of Antidepressant Medication Effects in Normal Controls Subjects (IRB#: 00-11-038-13) - Subject has had a normal physical exam within one year prior to entry of the study - Capacity to give Informed Consent Exclusion Criteria: - Subject has serious medical illness, such as high blood pressure, heart disease, renal impairment, or cirrhosis of the liver. - Subject meets DSM-IV Axis I criteria for a mood, anxiety, cognitive, or psychiatric disorder; or meets criteria for cluster A or B axis II diagnoses.
