Neuroscience PhD Chance?

[NeuroGrad]

Hello everyone. I want to apply to Neuroscience PhD programs this fall and am wondering if I am aiming to high for the schools I want to apply to. First off, I have a GPA of 3.68 and am graduating Cum laude at UC San Diego with a BS in Neuroscience. I am doing a BS/MS program doing neuro research for my MS, and should have my masters degree in Biology by next spring. I have two years of research experience under my belt, and a great GPA, but my GRE scores are not so hot (Q: 630; V:550; AW: N/A yet). I also plan on applying for some graduate fellowships in the fall. I really want to apply to the following:

MIT

UCSF

UCB

BU

Columbia

UW

None of these school list a minimum GRE score. Do I have a good chance? Appreciate your input!
