Neural Simulator

[Gene Wallenstein]

I'm looking for a neural simulator which has the capacity to 
model "circuits" based on the cellular level. I've heard about 
GENESIS but was told that it is designed mainly to model single 
cells. Are their any decent, hopefully FTPable, packages out their 
that don't take a gig of disk space yet are still general enough
to do something like this?

                Thanks in advance,
