<p>If you are talking about grad school (PhD program) for neuroscience, then the thing that will matter most is a demonstrated ability and interest in research. The most important thing, even more so than GRE or GPA, is your undergrad research experience. You still need good GPAs and GREs to get in the door, but publications and an ability to demonstrate (in interviews) an understanding of the research you did (not just perform experiments you were told to do) will be the key to getting into a good grad school. But if you can figure out what type of research you really like to do first, that will dictate more where you end up both in a lab and as far as which institution you might be at. Having a large variety of undergrad research options to explore, in my opinion, is extremely useful for an undergrad bioscience major with aspirations of grad school, which is why I would recommend larger research oriented schools over LACs. Med school admissions is a little different in that research is nice, but it isn’t the end all.</p>
