Laboratory for Neurocognitive Research

Research and Teaching

Research Topics:

Dr. Ettenhofer's Laboratory for Neurocognitive Research studies brain-behavior relationships after traumatic brain injury (TBI). The primary goal of this research is to identify factors related to outcome and recovery after TBI and to aid in the development of targeted treatments. Current studies focus upon the development of robust eye-tracking indicators of neurocognitive status to aid in management of TBI, and the use of virtual reality (VR) for assessment and remediation of driving abilities after TBI. Primary study populations include military personnel with TBI related to combat as well as civilians suffering from TBI related to sports and accidental injuries. Previously, Dr. Ettenhofer has also conducted research examining neurocognition, neuroimaging, and functional abilities in HIV/AIDS, aging/dementia, and adult ADHD.

Current Grant Support:

Department of Defense (DOD) Applied Research and Technology Development Award (ARATDA); Center for Neuroscience and Regenerative Medicine (CNRM) - CNS Repair and Recovery Award; DOD Congressionally Directed Medical Research Program (CDMRP); USUHS Intramural Research Award.

Methods and Approach:

Eye/gaze tracking; Virtual reality; Neuroimaging (i.e., MRI, DTI, fMRI); Electroencephalography (EEG); Neuropsychological assessment.

Medical Student Teaching:

MPS Course Director for MS-I Neuroscience & Behavior Module. Lectures on Psychological & Neuropsychological Assessment, and Traumatic Brain Injury.

Graduate Student Teaching:

Research Methods I (MPO901) and Neuropsychology (MPO533). Lectures on Traumatic Brain Injury, Human Cognitive Neuroscience, Technology Development in Behavioral Medicine, Cognitive Remediation, Historical Perspectives on Brain-Behavior Relationships, and Health Psychology.


Dr. Ettenhofer currently mentors five psychology graduate students, one post-doctoral fellow, three research associates, and two volunteers in research activities. He also provides clinical mentorship to seven psychology graduate students.
