For the last few years we have been studying interspike interval
codes for the pitch of complex tones and for speech elements at
the level of the auditory nerve and the cochlear nucleus.
A large set of auditory nerve interspike interval distributions
can be found in two papers that just came out in J. Neurophysiol.
in September:
Cariani, P. and Delgutte, B. Neural correlates of the pitch of complex
tones. I & II, pp.1698-1734. September, 1996.
Many other relevant papers are cited there.
I also have a considerable amount of data from the cochlear nucleus
that's in poster form. Let me know more specifically what you're
looking for and I would be happy to give you pointers.
