The purpose of this study is to examine associations between an athlete's concussion history, perceived social support, perceived stress, and kinesiophobia (fear of movement) symptoms. A better understanding of these associations may help clinicians and researchers understand the importance of implementing mental health care into the rehabilitation process of recovering from a concussion.

In this study, we want to find out more about the relationship between jumping and running tasks and a virtual reality task. We also want to find out how a recent concussion (within the last 9 months) may impact completing these tasks.

Do you ever notice that you feel more energized or alert when meeting new people and forming first impressions? Other times, a first meeting will rub you the wrong way and you may feel less attentive. If you've experienced one or both of these, you may wonder: What makes a good first impression? How do you know you want to become friends with someone? What information do we pay attention to when interacting with someone for the first time? Good questions! Neuroscience and psychology researchers wonder about the same things. Here at the Social Neuroscience and Health lab, we study how the brain and the immune system work together to influence our behaviors and experiences. The Friendship Pathways Study is a research project aiming to answer questions about how the brain and immune system communicate when meeting new people and forming friendships.

Do you have a child between 12-14 years of age who is healthy but has some symptoms of anxiety or unexplained nervousness? You may be able to take part in a study with your child to better understand how anxiety develops across adolescence in brain and stress responses. Compensation provided.

Early detection of memory problems (such as seen in Alzheimer's Disease) in older adults is essential for planning strategies to improve patients' everyday function and quality of life. While patients and family members often talk to clinicians, our proposed research system is meant to capture changes in memory before they are identified by clinicians. You are being asked to be in the study because you are interested in helping us determine whether changes in voice could be related to physical function and memory changes over time.

The study aims to use a special chemical called [11C]UCB-J to measure the connections between brain cells and how these may be different between people with and without diabetes.

We would like to learn about how people who apply for healthcare financial assistance experience the application process, including things that make the application process work well or that were challenging. At this time we are not able to offer interviews to people who applied to UNC or Duke, we are interested in hearing from people who applied to other programs (such as Atrium, Novant, Wake, Vidant, ECU, Cape Fear Health Net, Physicians Reach Out, or Project Access).

This study aims to find better ways to serve children with autism spectrum disorder (ASD). We will use 3 rounds of online surveys to develop a list of functionality features that are most relevant for serving school-age autistic children. We hope this list can be used to improve services and support for those who are on the autism spectrum.

Are you someone living with Parkinson's disease? If so, you are aware that in addition to symptoms affecting movement, people with Parkinson's disease also experience non-motor symptoms such as problems with mood and motivation which can be difficult to treat. If you have been living with Parkinson's disease for at least 4 years and take medication for Parkinson's disease, you may be eligible to participate in a research study aimed at treating low motivation with a form of non-invasive brain stimulation called transcranial magnetic stimulation (TMS).

The purpose of this study is to use an MRI and other devices to observe the brain and body activity that happens when people feel certain emotions.
