I agree with Jaya, I'd suggest SH-SY5Y to begin with as it's probably the best characterised one. There are also several established protocols for differentiation into mature neuronal phenotypes, which may or may not be of help to you depending on what you're studying...
@jaya viswanathan yes we have that cell line also but growth of this cell line is very slow so i am searching the alternative of that. Jaya do you any experience with your said cell line, so please suggest me how to maintain that cell line
