My experience is a bit odd, so wait for a more 'regular track' person to chime in but I'll throw my advice into the mix:
Neuroscience is a huge field and people with careers in neuroscience come from a variety of backgrounds though a few things are constant: If you want to research with a bit of choice on what you do you need a Phd. Otherwise you can research with a BS though you'll be told what to do and you be constantly at the whims of funding which you have no control over (very low job security). So if you want to do neuroscience on a research topic of your choice, get a BSc (doesn't have to be in neuroscience could be in auxilary field), get a Phd. There are many people with neuroscience Phds looking for work so, like virtually all academic fields, you are going to be facing stiff competition the whole way. It's a long, hard road and the main reward will be the chance to work on exactly what you want. Again, because neuroscience is a massive, relatively new field, there is potential to enter the field from a variety of angles (I entered from physics) and 'do' a bunch of different things. If you have any other questions maybe I can help. Also, where do you live? If you live in the States/Canada, expect the whole journey to take at least 8 years (assuming you work very hard and are very bright) but probably 10. If you live in UK/Euro, it's possible to do the whole thing in 6 but will prolly end up taking around 8. I can't comment on the length of studies in other areas.
