I suspect this goes a bit further, although there's a related article in
Neural Networks, Vol 7, Nr 3--Matsugu and Yuille, 1994, "Spatiotemporal
information storage in a content addressable memory using realistic
neurons." pages 419-440. Once you have a coherence detector, the
selective pressure will be on reducing the information needed to declare
a coherence is forming and doing the declaration as early as possible.
That will evolve towards a system where the downstream elements will cue
the upstream elements as soon as they've declared the coherence so that
the upstream elements can move to the next coherence without finishing
the previous one. Freeman seems to be pushing me to think in this
direction, but my foundations aren't firm yet. Something of this nature
is needed to address the evidence for nonstationary dimensionality in
EEG dynamics.
