Call the programs that you are interested in and find out when the deadlines are. University of Chicago had an October 1, 2001 deadline. Penn has a December 1, 2001 deadline. All other programs fall somewhere in between. Keep in mind that all programs receive many apps but will interview only a handful. Many programs have already selected and scheduled their potential candidates to interview.
Also remember that it takes the SFMatch people around 2-3 weeks to compile your stuff and send it out to the various programs. And, at this point most of us applicants have already interviewed at ~2-3 programs.
That said, Neurology is a relatively easy match. The top programs will be as competitve as in any other field. But after that, it's easy pickings.
My suggestion. Call the programs and ask.
Good Luck.
