Noninvasive Study of Brain Connectivity With EEG and NIRS

Completed

Conditions studied: Healthy Volunteers

In brief

Background: \- Different regions of the brain are activated when a person performs a task. Electroencephalograms (EEGs) and near-infrared spectroscopy (NIRS) are tests that detect changes in the brain. EEG looks at changes in electrical signals, and NIRS looks at changes in blood flow. These tests can detect local changes in brain activity in a safe and noninvasive way. Researchers want to study brain activity more closely by combining these tests. Objectives: \- To use EEG and NIRS to study brain activity during specific tasks. Eligibility: \- Healthy volunteers at least 18 years of age. Design: * Participants will be screened with a physical exam and medical history. * Participants will have between one and five testing sessions. Each session will be 1 to 2 hours long. The tests given at each session will be determined by the researchers. * Participants will have EEG and NIRS tests, given either separately or together. During these tests, participants will perform tasks of thinking and reasoning. * Participants may also complete optional tests of thinking and reasoning. These tests will be given on paper or on a computer.
