Sponsor's own description
This study will use magnetic resonance spectroscopy (MRS) and the drug gabapentin to examine the role of the brain chemical gamma-amino-butyric acid (GABA) in regulating emotions in healthy people. Gabapentin, which is used to treat epilepsy, increases GABA concentrations in the brain. MRS, similar to magnetic resonance imaging (MRI), is a diagnostic test that uses a magnetic field and radio waves to produce images of the brain. Non-smoking, healthy normal volunteers between 18 and 60 years of age may be eligible for this study. Candidates are screened with a medical history and physical examination, psychiatric evaluation, blood and urine tests, and an electrocardiogram (EKG). At three separate clinic visits, participants are given either gabapentin or a placebo (an inactive look-alike capsule). They take placebo at one visit, 600 mg of gabapentin at another visit, and 1200 mg of gabapentin at another visit. One hour after taking the capsules, the amount of GABA in the brain is measured by MRS. For this procedure, the subject lies on a table that moves into the MRI scanner (a narrow cylinder), wearing earplugs to muffle loud knocking and thumping sounds that occur during the scanning process. The procedure lasts about 45 to 60 minutes, during which the patient is asked to lie still for up to a few minutes at a time.
