In the 18 minute clip on the below link, Neuroanatomist Jill Bolte Taylor talks at the TED conference about her personal experience of a stroke.
She had a blood vessel burst in her left brain causing her to gradually lose functions. Because of her background, she was able to monitor the shift and explore the consequences as a scientist. The experience also gave her a spiritual epiphany. She describes the experience and her discoveries. A remarkable story.
In the clip, she describes (and shows) the 2 hemispheres of the brain. She goes over how the hemispheres differ, that the left brain (controlling the right side) is the serial processor, the mathematician and organizer. The right brain is the parallel processor, the creative and spatial side.
Because the impairment was in her left hemisphere and she evidently carries the common viewpoint of neurobiologists that consciousness is an effect of the brain, she concludes that spiritual experiences are a function of the right hemisphere and the ego of the left.
That is where I think she is incorrect. Firstly, as well as being hemispheric, the brain has vertical variation in function. What is commonly called Triune. Secondly, consciousness itself has gradations of expression.
The ego is actually sustained in the mid-brain, know as the paleo-mammalian or limbic. If the upper brain is impaired, the stories of the ego may go off-line, thus impairing its function. This would open her up to more expanded states of awareness, as she described. This is what techniques such as meditation hope to achieve in transcending the mind. The right brain contributes to the ego but is not its actual seat in physiology. (not that the ego has a reality or “place”. We’re talking about how the mind sustains a concept of self) Its also true that the right brains more open and spatial properties contribute to expanded awareness but is not itself the seat of that. Its better to think of the brain as a liaison with consciousness.
As I have commented here prior, we are consciousness itself. That consciousness expresses itself through form, through our physiology, and creates effects we experience as thoughts, emotions, and physical responses. The 2 hemispheres process different values of consciousness but do not create it. Consciousness is causal rather than an effect.
In the clip, Jill speaks of now being able to shift her attention from hemisphere to hemisphere. While there may indeed be mental activity evidence that that is what she is doing, in fact she is actually shifting conscious perspectives or viewpoints. She is shifting from localized mind to unlocalized non-mind, which will have its corresponding physiological symptoms. The liaison or interface will respond to the shift in awareness.
I don’t say this as a competing theory or idea but rather as the experience. When you open yourself up to consciousness through systematic exploration, you discover this as a deeper reality than that of being ego-mind or physical body. Its not that ego-mind is an invalid perspective, but as Jill observed, being purely in who you are leads to a much more satisfying life.
