In the Nielsen Brain & Behavior Lab, we are interested in answering questions about the organization of the brain and how neurological and psychiatric illnesses disrupt its organization. To answer these questions, we use a variety of analytical techniques to extract quantitative information from MRI scans. We currently have projects that investigate how the brain is affected in patients with autism, dementia, and mood and anxiety disorders. Our hope is that the information we learn as scientists will inform and improve the way clinicians diagnose and treat their patients.
