I agree that these results contradict to an immediate readour of an tonotopic
pattern while they fit well to Langner's periodotopy in the IC as well as to my
idea of pitch via a cepstrum-like second (neural) analysis after cochlear
frequency analysis jointly corresponding to autocorrelation of the original
signal. Do you suggest a different explanation?
