I don't know any specifics on the pre-med program, but Carleton is very highly regarded in the physical sciences. Here's a link to their pre-med page
Carleton College: Pre-Medical Program
also, they've just formed a neuroscience concentration

My daughter is interested in neuroscience (but not pre-med) - I emailed the director of the program and she said she'd be happy to talk to her when we tour.
Hope this helps
