I disagree. Oliver Sachs reported that one of his patients while having
a migraine aura had the separation of self into two consciousness.
This can be understood as the self as an attractor of all experiences.
When the migraine created choas two selves were created. When the
client tried to integrate them back into each other they could not.
It sort like a disk balanced on a stick. When it is sent viberating
wildly. Two centers emerge oscillating around the really center.
Further support was collected with vestibular stimulation. A woman
who was paralyzed in her arm due to brain damage (Science News, October
21, 1995 page 271) was NOT conscious of her condition. When cold
water was put in her ear she now knew she was paralyzed. When the
effect wore off she now knew she was NOT paralyzed even though she was.
She denied ever saying she was paralyzed and did not remember the

researcher G. Bottini, E. Paulesu, R. Sterzl, E. Warburton, R.J.S. Wise,
G. Vallar, R.S.J. Frackowlak, & C. D. Frith in their article "Modulation
of conscious experience by peripheral sensory stimuli" revealed that
cold water ran in the ear of brain damaged patient who had lost the
sense of touch regain the sense temporally. "We show that in normal
subjects touch and vestibular signals share projectionss to the putamen,
insula, somatosensory area II, premotor cortex and supramarginal gyrus. In
our patient a subset of theres regions (right putamen and insula) was
pared by the lesion and was maximally active when touch and vestibular
stimulations were combined." (Bottini & etc. 1995)
All these example suggest correlational opponent processing to me.
