We are conducting a study at the University of Arizona to understand the effectiveness of a six-week course of light exposure on cognitive functioning, mood, activity, and sleep in people that have suffered a head injury leading to a mild traumatic brain injury or "concussion." Participants will undergo a series of surveys and tasks that measure emotional and cognitive ability. Throughout the visit, we will be recording heart rate using a small heart rate monitor.
Participants will also complete two one-hour MRI scans, where "pictures" of your brain will be taken while you rest quietly. Participants will also be asked to wear a wrist activity monitor and complete daily sleep diaries.
