"The mediating role of the brain can perhaps be best envisaged in terms of synergetic concepts: In thinking or making plans certain parts of the brain undergo coherent, collective activity states of possibly a great number of neurons, where concepts or ideas function as, or are represented by, order parameters of these collective activities. This would mean that in H. Haken's terminology of synergetics neurons or certain states of them (as parts of World 1) become enslaved by elements of World 2 (psychic events) and World 3 (mental entities)."
