Cost of doctorate in cognitive science or neuroscience?

[tposside]

I'm a freshman in college at a top 15 liberal arts college. I'll be about 14.5k in debt when I graduate if everything goes according to plan.

I'm planning to major in cognitive science and I figured I should check out some of my post-grad options. I know there are some fields in which grad school costs a lot and some in which tuition is generally lower. Where do cognitive science and neuroscience fit into the picture? I searched around for an answer before I came here and couldn't really find a satisfactory one.

I realize it probably depends a lot on your transcript and where you go, but I'm asking about the average cog sci student and neuroscience student compared to other fields.

You should not be paying for a PhD in cognitive science or neuroscience. Most places will waive tuition and provide a living stipend.
