Official title

Studies of Frontal Lobe Function During Cognitive Stimulation as Measured With Oxygen-15 Water Positron Emission Tomography in Normal Subjects and Patients With Neuropsychiatric Disorders

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The purpose of this study is to use brain imaging technology to investigate the role of the frontal lobe of the brain in the thinking of individuals with schizophrenia and other neuropsychiatric disorders and healthy volunteers. Participants in this study will undergo a positron emission tomography (PET) scan of the brain while performing neuropsychological tests. Some of the tests involve cognitive operations that depend upon the frontal cortex. Interactions between frontal lobe activation, cognitive behavior, and neuropharmacology will be assessed by measuring regional cerebral blood flow (rCBF) during treatment with drugs that may affect frontal lobe physiology.
