Adults: Healthy Volunteers

This research study is enrolling people to help us understand how physical activity, daily rhythms, and light affect mental health. 

Researchers are looking for healthy volunteers to help us learn more about how the brain works. We need to learn more about how the brain works so that we can learn more about how brains work in people with mood and anxiety disorders.

Several investigational studies are measuring proteins in the brain and body using Positron Emission Tomography (PET) technology to better understand the biological basis of mental illness and to eventually pave the way for new treatments.

How we feel can impact the choices we make. Feelings of sadness, stress, or pain can change our behavior. Researchers want to learn more about the choices we make when feeling bad.

Researchers are enrolling healthy volunteers for an outpatient research study to learn about the brain. A part of the study evaluates how the brain activates and represents memories. Participants will watch videos created in the “1 Second Everyday App” during a brain scan (MRI) and again during a MEG (magnetoencephalography) scan.

People feel different levels of pain. These differences are caused by social, cultural, and biological factors. Researchers at the National Institutes of Health are trying to better understand the different factors that impact pain and how people experience pain.

Adults, ages 18 to 70, who are in good physical and mental health are invited to participate in this research study. The goal of the study is to create a list of pre-qualified research volunteers who would like to participate in additional NIMH studies at the NIH Clinical Center in Bethesda, Maryland. 

This part of the facial recognition study is enrolling healthy adults without psychiatric conditions, between the ages of 18 and 35, who are in good medical health, and have a bad memory for faces. The overall purpose of the study is to learn about the brain, thinking and memory in people with and without autism spectrum disorders.

To learn more about what happens in the brain when someone has thought about or attempted suicide, researchers study a comparison group of people without suicidal thoughts.

How does brain activity impact transcranial magnetic stimulation (TMS) response? 

This research study seeks healthy adult participants to explore how transcranial magnetic stimulation (TMS) affects the brain. TMS is a non-invasive method which uses a magnet placed outside the head to stimulate precise locations inside the brain.

This research study seeks to learn about the brain, moods, memory, thinking and concentration in healthy adults and compare them to those who have HIV infections.
