Integrated Eye Tracking and Neural Monitoring for TBI: Optimization

This study (N=100) will be a correlational study to assess cognitive function in healthy controls, individuals with mild TBI, and individuals with moderate-to-severe TBI.

In general, participants will provide demographic information, medical history, and details of their head injury. Participants will also complete a brief neuropsychological assessment to obtain an index of cognitive ability, along with the Fusion Test with eye tracking and linked EEG. MRI data may also be obtained.
