The purpose this study is to examine how individual differences in health changes (muscle strength, blood pressure) and behavioral changes (sleep, physical activity) impact memory, attention, and the brain. We study these relationships in among a variety of older adults, including those with a history of concussion, traumatic brain injury (TBI), and posttraumatic stress disorder (PTSD). The long-term goal of this project is to identify modifiable factors that exacerbate or protect from age-related cognitive decline.

Children who suffered a stroke before or shortly after being born that was caused by blockage of blood flow in an artery, it often results in the child showing some weakness on one side of their body.

With this study, we want to find out if a type of therapy may help children who have weakness on one side of their body due to perinatal arterial ischemic stroke, learn how to better use their weaker arm.

All children will be in the study for about 13 - 15 months. Some children may be in the study for a longer period, depending on which treatment they receive during Phase 1 of the study. The I-ACQUIRE therapy involves fun learning and play, self-help activities, and manipulating interesting toys and objects.

This NIH-funded project will investigate patient-specific factors that may influence response to therapy for language impairment after stroke, or aphasia. Results from this work will assist with better estimation of prognosis for stroke survivors with aphasia, which could empower patients and families to make more informed health care decisions about how to pursue the most appropriate rehabilitation services based on their unique characteristics, such as genetics, cognitive skills, and brain structure after stroke.

The purpose of this study is to better understand the way the brain works in people who have depression and people who have previously been depressed. We are also testing healthy subjects for comparison. We hope our findings will lead to better ways to diagnose and treat mood disorders in the future. Participation involves an initial phone call and a 2 to 4 hour visit to find out if you are eligible. This visit will include completing questionnaires and interviews. If eligible, participants will have a second 3-5 hour visit for an MRI scan. Two months after the scan, participants will complete daily online questionnaires for 7 days. This process is repeated 2 months later (4 months after the scan). Participants can make up to $220 for full participation.

The purpose of the study is to look at how our brain networks interact for different mental functions and how individual differences in brain structure and function determines individual differences in behavior. During this study, we use magnetic resonance imaging methods: functional magnetic resonance imaging (fMRI) and diffusion weighted imaging (DWI). Functional MRI (fMRI) and DWI are typical imaging methods that use a strong magnetic field and radio waves to make pictures of your body. The total length of the study will be between 3 and 4 hours, including up to 2 hours outside the MRI scanner and 2 hours in the scanner.

The purpose of this study is to explore how family caregivers and persons with memory loss communicate and if certain ways of handling stress, such as mindfulness-based self managements, are helpful for family caregivers. You will be in the study for up to four months from the time of consent to the time of final study data collection. There will be 4 telephone or video calls, and each will take approximately 30 – 135 minutes.

The purpose of the study is to investigate how different parts of the brain are wired together and how they interact to form complex human behavior, and how our brain’s design makes each of us unique individuals. Different types of imaging methods - functional magnetic resonance imaging (fMRI ) and diffusion weighted imaging (DWI), imaging methods that use a strong magnetic field and radio waves to make pictures of your body, will be used to gather information from participants. No X-rays or other radiation is used in fMRI or DWI. Eye movements may be tracked as well, and you will be asked to respond to various conditions, questions, and stimuli.

The purpose of this study is to record the personal experiences of those who have had Deep Brain Stimulation (DBS) using the Vercise™ System, for the treatment of Parkinson's Disease.

The purpose of this study is to collect information and evaluate outcomes for Abbott Deep Brain Stimulation (DBS) systems that are approved and sold in your country.

In order to evaluate how the DBS system performs, data will be collected before, during and after DBS implant when you visit the study doctor. The data collected will include information on your movements, feelings, daily activities, and DBS program settings.

The information gathered in this study will add to the understanding of treatment options for future patients receiving DBS.

This study looks at how brain response to emotional cues affects behavior. This research is being done to better understand the brain and behavior system in young adults in order to help develop interventions in the future. To participate in this study you will need to come to the OSU campus 3 times over a 2-3 week period. Each visit will last from about 2 to 5 hours.
