Yeah, neurology is about the brain. The brain is part of the body. Biology covers all of that, so I’m not sure what you’re getting at. Psychology (behavior, conscious or unconscious) is not neurology (abnormal structure of brain, spinal cord, and peripheral nerves.) There are literal brain scans to show that trans people have brain maps that are SIGNIFICANTLY, if not matching, their preferred sex rather than the one they were assigned at birth. That is part of biology.
