You also have to consider that "neuroscience" is not the only degree that teaches you, well, neuroscience. It can also be called "neurobiology", "biopsychology", "psychobiology", and various other things. In the end, it teaches you the EXACT same stuff. And you can always take classes outside your major if you feel the major you picked doesn't have enough bio or psych or phylosophy (those are usually the departments that teach neuroscience-type stuff). Seriously, don't get stuck on a name. I got a major in one of those (biopsychology) and it was exactly the same thing that a cousin did in neurobiology and a friend did in neuroscience. There's really only so much we know about the brain, and that's what you'll learn.
