    I very much appreciate both your well founded criticism and
your courage to frankly utter it. However, I feel we have to be
a bit more cautious. Pitch isn't already the whole hearing, and
evolution didn't follow the need for good musicians. I guess,
survival of an animal rather depends on localization. How does
it work? Except for very low or high frequency, cochlea performs
a Fourier Cosine Transform. This is only the first step. In
order to map location, the brain has then to perform some kind
of inverse transform as do radar and sonar. Of course, the only
way for neurons to do so is not Fourier analysis but a
correlational, i.e. coincidence analysis. Where might this
happen? I learned: A first coarse but fast cross-correlation is
very likely to occur within the SOC. Auto-correlation might be
one of the most important cortical functions. If this
speculation of mine is true, it could hopefully be the starting
point to a fist understanding of other (presumably younger)
patterns than location. Anyway, I wo
