the best reference i know for auditory physiology is "An Introduction to the
Physiology of Hearing", by J.O. Pickles.  It will surely have the answer to
this question and many others about auditory physiology.

To give something of an answer myself:  it is hard to say what is really
mandatory.  The Superior Olivary complex is generally assumed to be
responsible for spatial localization.  I've heard recently of work (sorry,
i don't have a reference) where the SOC was lesioned and animals could still

according to pickles, the ic receives input which contains information about
timing (spatial localization) and complex frequency analysis.  it seems to be
a center for both localization and source identification.  as such, it would
seem to be a critical synapse in the ascending pathway.
