CU Boulder has a tight relationship with our Medical school, and a bus runs between Boulder and the Aurora Medical school campus. So you consider doing research work as an undergraduate at Anschutz Medical campus.
I would write
to the neuroscience faculty in Aurora and ask if they take undergraduates. A car might be good to have to drive to Aurora, but the bus leaves from Boulder Table Mesa bus stop to get to the Medical school. I personally know an applied mathematics student in Boulder who worked summers and term time in Aurora on bioinformatics. He got into the PhD in bioinformatics at CU Anshutz and very happy. I suspect neuroscience students who are motivated can get research positions at our medical school. That would make the degree a very strong one, but check in with neuroscience faculty to be sure this is possible for you.
