|Brief Title ICMJE||Noninvasive Study of Brain Connectivity With EEG and NIRS|
|Official Title ICMJE||Non-Invasive Study of Brain Connectivity Using Combined EEG and NIRS|
- 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.
- To use EEG and NIRS to study brain activity during specific tasks.
- Healthy volunteers at least 18 years of age.
Objective: To record near-infrared optical signal (NIRS) simultaneously with EEG signal and correlate hemodynamic and neuronal responses, and to understand brain connectivity associated with cognitive functions using combined EEG/NIRS technology
Study population: 40 healthy volunteers
Design: The study will aim to capture the dynamics of brain interactions on two different scales by combing EEG (neuronal) and NIRS (hemodynamic) techniques. We will then correlate the two responses to study the brain connectivity in a more comprehensive way.
Outcome Measures: graded changes in blood flow and blood oxygenation, measured with NIRS, along with electrical signals recorded by EEG in response to different functional tasks.
