You might want to look slightly outside the Neuroscience department. Math and CS departments also do quite a bit of computational neuroscience.

Here at NYU, we've got at least 5 computational neuroscience people within the courant institute (math+CS depts), and there are several more in the actual neuroscience department. Plus we have a computational biology Ph.D. program within cims.

I know Rutgers has the BioMAPS computational biology program, and I think princeton has something similar.
