Fabulous question. I believe not. The only mammalian model that makes sense to me requires there to be only ONE point of central executive in the brain. If more than one could arise, you'd have chaos. All coordination of bilateral activity would be impossible, much less the initiation of action or a chain of perceptual focus or cognitive reasoning. With all animals above worms having bilateral symmetry, the introduction of one side becoming dominant must have ocurred very early in evolution. Thus ALL species with any cortex at all must have circuitry that prevents the bigger parts the nervous system from becoming fully decoupled and 'going' rogue.
