Re: AW: the number of fixed categories in absolute pitch

Ok, that is interesting but I was refering to the use of the term "3 bits"
rather than to dimensionality.

There is recent evidence from neuro-imaging that the processing of pitch
information in the human brain is indeed two-dimensional.

So are we to understand, from "NAP subjects can 'transmit' about 3 bits
on a
single frequency dimention, while AP subjects can transmit about 3 bits
on
each of two dimensions: Pitch height and Chroma" that the brain is a
binary
system?
