Are you an adult who does not have high blood pressure and is interested in research? This study will investigate how the brain regulates the body’s response to stress and how infection with HIV or pre-hypertension affects regulation. Your heart and brain activity will be measured while you are at rest, during a mentally stressful task, and while you feel angry. The study will also test whether a breathing exercise improves regulation. People with and without HIV and pre-hypertension will be included. To participate in this study, you must be between 21 and 65 years old and not have high blood pressure. This study is located in Miami, Florida.
