Creativity in Asa H 2.0

Asa H discovered and reported to me that (in the context of something like a neural network with feedback or the related models of consciousness)  "feedback narrows view." This was something I did not know.   Much like with oscillators in electronics, feedback narrows bandwidth.  Subsequently, in searching google I find evidence that cortical feedback in the human brain may restrict the receptive field of that cortical cell assembly.
