I would not choose an undergraduate institution based upon perceived strength of specific undergraduate programs except at select institutions where they offer a unique learning experience at that specific discipline that you cannot obtain elsewhere (e.g. Econ at UChicago, various engineering disciplines at MIT/Caltech, so on and so forth).
1. You might not pursue neuroscience (or even science at all) in a year.
2. No one truly cares about program rankings, save for perhaps "undergraduate business school rankings." Even then the prestige of the institution usually far outweighs any perceived difference in undergraduate programs.
3. If your purpose is getting into medical school, WashU is far better than Miami.
In the end, there is very little difference in curriculum for undergraduates in any field. Differences in any program is generally related to faculty, so to see relative strength of programs you could probably Google Scholar neuroscience faculty from each school and see which school's faculty generally have a stronger CV (# pubs, H-index). WashU is most likely the stronger program due to its biomedical research pedigree.
