The two cases require a different arrangement of the > same ideas, but node-based theories cannot express this. The (now) "classical" solution to this problem is synchronicity, The cell assembly for RED and the cell assembly for BALL fire in synchrony if they are to express that it is the ball that is red. This idea dates back to the 70es (Christoph von der Malsburg, "A correlation theory of brain function", he actually cites someone from last century who had the same idea) but was confirmed only recently (1991 or so, Gray, Konig, Engel, Singer, in Nature: binding by motion).
