Play Games Inside a Real Brain Scanner

Adopted and Foster Teens Ages 12–15 Can Earn Up to $245 in a UCLA Study

✅ Participants receive up to $245 for completing all study activities

✅ Teens participate in interactive brain games, lab activities, and MRI scans

✅ Get a photo of your teen's brain from the MRI scan

Could the tiny microbes in your teen’s gut influence how their brain develops? The Teen Bugs Study is designed for adopted and foster teens ages 12–15 and explores how organisms in the gut, such as bacteria and viruses, may affect brain and body development during the teen years. Researchers are especially interested in how these gut “bugs” may relate to mental health, including common challenges like anxiety and depression.


As part of the study, teens will participate in interactive activities during an MRI scan, while parents complete questionnaires that provide helpful background information.


You’ll also have the opportunity to follow your teen’s development over time. The study includes several check-ins over approximately five years, helping researchers understand how teens grow and change during these important years.

Meet the Lead Researcher

Dr. Bridget Callaghan

Dr. Callaghan is a psychologist and developmental neuroscientist at UCLA. Her research focuses on how early experiences, including stress and environmental factors, shape teen brain and mental health development. She has extensive experience conducting research with teens in safe and supportive lab environments.

Dr. Jennifer Silvers

Jennifer Silvers, Ph.D., is an Associate Professor in the Developmental and Social areas of the Department of Psychology at UCLA. Her research uses a combination of behavioral, physiological, and neuroimaging methods to understand how children, adolescents, and adults regulate their emotions, as well as how close relationships, such as friends and family, shape and support emotional experiences across development.
