Study Summary
Background: Noninvasive brain stimulation (NIBS) may help diagnose and treat psychiatric and neurological illness. But there is not enough research on how to apply NIBS. This includes how strong to make it, where on the brain to apply it, and for how long. Researchers also want to see what the brain is doing when it receives NIBS. Objective: To increase the effectiveness of NIBS. Eligibility: Healthy native English speakers ages 18-65 Design: Participants will be screened under another protocol with: Medical and psychiatric history Psychiatric evaluation Physical exam Urine tests All participants will start with a 2-hour visit for screening. (see below). They may learn how to do tasks that will be used later. After the screening session, they will be scheduled for an MRI session. The next part of the study is 4 substudies. Each substudy includes up to 4 sessions. A session is usually 2-3 hours but can last up to 8 hours. Participants can join multiple substudies, but only 1 at a time. They can do only 1 session on a given day. Each substudy includes the following: Behavioral tests: Interviews; questionnaires; simple tasks; and tests of memory, attention, and thinking Electromyography: Small sticky electrodes on the skin measure muscle activity. Transcranial magnetic stimulation: A wire coil is held to the scalp. A brief electrical current passes through the coil and affects brain activity. Magnetic resonance imaging (MRI): Participants lie on a table that slides into a machine that takes pictures of the brain. A coil is placed over the head. They will perform simple tasks while in the scanner. They may also get TMS. Electroencephalography: Small electrodes on the scalp record brain waves. Sponsoring Institution: National Institute of M ...
