Behavioral neurology is a medical field that studies how your brain affects the way you act. Your brain is the part of your body that is responsible for thinking, feeling, and controlling your movements. Behavioral neurologists use tests, scans, and other tools to understand how changes in the brain's function cause changes in behavior. They use this information to help diagnose and treat people with brain disorders that affect their behavior. So, behavioral neurology is like a detective trying to figure out how the brain affects the way a person acts.
