Yet the brain still relies on hierarchies of models (or archetypes) to make any sense of the world at all. I mean, surely there is little variation in what people consider a nose or the sensation from touching a bumpy surface and how they would describe it. (I'm speculating here, of course.) Thee difference you're referring to in activation in response to stimuli, as I understand it, is a result of the way and timeline that the models were learned, but it doesn't change the fact that the cortex relies on hierarchies of models to form a representation that we understand to be reality. That is, if I understand you correctly and am not too outdated here.
