Official title

Integrating EEG/MEG and fMRI: Activity Correlation Between Frontal and Temporal Lobe Structures in Schizophrenic Patients, Their Siblings and Unrelated Normal Volunteers

Brief summary

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

This study will explore how the brain works during memory testing in an effort to understand why some patients with schizophrenia have memory difficulties. Patients with schizophrenia and their unaffected family members are eligible for this study. Studying family members may help identify the genes related to the memory deficit in schizophrenia. Normal volunteers will also be studied. Normal volunteers, patients with schizophrenia, and their family members interested in participating in this study will be screened with a complete medical examination and psychiatric assessment, and performance of simple tasks. Study participants will be shown numbers on a screen and asked to recall them after a brief period. This will be done during electroencephalographic (EEG) recording, in which electrodes attached to the scalp measure the brain s electrical activity. The same test will be repeated while the patient has magnetic resonance imaging of the brain. The combined MRI and EEG testing will permit better localization of the brain s electrical activity. ...
