Those were important to me too. I will be attending northwestern university in the fall and they have faculty specialized in those areas. They do a lot of research in stroke and cerebral palsy which both were most important to me. Most schools I visited had faculty specialized in Neuro and Pediatrics but northwestern was the first school I saw with extensive research in it. I would just start trying to visit schools and get to know the faculty because all staff will be supportive from what I've seen and will give you the opportunity to work within their specialties for research aid or projects. Best of luck to you!
