Study Summary
Background: People tend to pay more attention to one side of space than the other and this may be due to differences in the structure and function of the two sides of the brain. We are interested in whether we can detect those difference with magnetic resonance imaging (MRI), transcranial magnetic stimulation (TMS), and electroencephalography (EEG). Objective: The purpose of the study is to understand how differences in brain structure may cause people to pay more attention to one side than the other. Eligibility: Healthy adults ages 18-35 Design: Participants will be screened with a neurological exam. Participants will have 2-3 visits for a total duration of about 7/8 hours. Women of childbearing age must have a negative pregnancy test before each MRI scan. Visits may include: Physical exam Tests of attention, and thinking TMS. A brief electrical current will pass through a wire coil on the scalp. Participants will hear a click and may feel a pull. They may be asked to tense muscles or do tasks. Magnetic resonance imaging (MRI) scan for a maximum of 1 hour. Participants will lie on a table that slides into a cylinder in a strong magnetic field. They will do tasks on a computer screen or lie still. They will get earplugs for loud noise. EEG for no longer than 5 hours, with most lasting 3 hours. Gel and a cap with electrodes will be placed on the scalp. They will record brain waves while the participant gets TMS or does nothing. Questions about participants dominant hand and about the MRI.
