The histogram of CSHW amplitudes seems to have very little information content, while the entire matrix of just-noticeable-differences of our experience seems to have a whole lot of information. If CSHWs are so important to determine a “brain state”, where is all the missing information?
Two points here. First, according to the theory -as Mike points out- the overall “mood” of the state is largely encoded in the low frequency harmonics, while the higher frequency ones are more important for semantic information. In a sense, you can think of the lower frequency harmonics as creating a set of buckets in which to put, juggle, and recombine the information provided by the higher frequency harmonics. Hence, while the specific information content of the experience might require a very fine level of resolution, both the valence and the broad information-processing steps might not. And second, there is more to the CSHWs than just the histogram of amplitudes. There is also a matrix of phase-locking relations between them, which increases the overall information content by a large amount.
