Seeing with "Right" side of brain and need to balance both sides

‘There is no such thing as fact (or truth), only interpretation’. Immanuel Kant

The brain is wider than the sky,

For, put them side by side,

The one the other will contain

With ease, and you beside.


Emily Dickenson

I truly am thinking the major part of our "Ego" is housed in the "left side of brain"...if nothing else on the on the "Need for Certainity"

,the right-side knowing there is very few 100% certainities.

The Way I See
" Looking at it all,
In the Fullest view, searching for all the context that I may.Yet finding the time hinders me, not time to look at every thing from, and from every point of view"-Michael Emery

The statement above was one source of my early life filled with great depression,due in a great part I live in a society rushing around in madness,not taking the time to truly see the "Context of it All"

THE DIVIDED BRAIN is a mind-altering odyssey about one man’s quest to prove a growing imbalance in our brains, and help us understand how this makes us increasingly unable to grapple with critical economic, environmental and social issues; ones that shape our very future as a species.
THE DIVIDED BRAIN follows McGilchrist on a journey of discovery as he travels to meet his biggest champions and critics and defends his unique vision of the implications of his theory. Dr. Ian McGilchrist is a soft-spoken British psychiatrist and neuroscientist but one who may have uncovered an insidious problem with the way our brains function. He believes that one half of our brain – the left hemisphere – is slowly taking power, and we in the Western world are simultaneously feeding its ambitions. This half of the brain is very proficient at creating technologies, procedures and systems, but it cannot understand the implications of these on the people and the world around it.
Has our society been hijacked by the left hemisphere?
Is it too late?
McGilchrist knows that if he is right, we may be creating the technologies and the conditions that will spell our own downfall. With the clock ticking on critical issues, he must make his case and find ways to restore the balance before it’s too late?-Dr. Iain McGilchrist

Roger Wolcott Sperry and split-brain theory

-Nobel Prize-  Sperry was granted numerous awards over his lifetime, including the California Scientist of the Year Award in 1972, the National Medal of Science in 1989, the Wolf Prize in Medicine in 1979, and the Albert Lasker Medical Research Award in 1979, and the Nobel Prize for Medicine/Physiology in 1981 that he shared with David H. Hubel and Torsten N. Wiesel. Sperry won this award for his work with "split-brain" patients.
  The brain is divided into two hemispheres, the left and right hemispheres, connected in the middle by a part of the brain called the corpus callosum. In "split-brain" patients, the corpus callosum has been severed due to the
Nobel Prize
patients suffering from epilepsy, a disease that causes intense and persistent seizures. Seizures begin in one hemisphere and continue into the other hemisphere. Cutting the corpus callosum prevents the seizures from moving from one hemisphere to the other, which then prevents seizures from occurring, thus allowing the patients to function normally instead of suffering from continuous seizures.
  Sperry first became interested in "split-brain" research when he was working on the topic of interocular transfer, which occurs when "one learns with one eye how to solve a problem then, with that eye covered and using the other eye, one already knows how to solve the problem".[17] Sperry asked the question: "how can the learning with one eye appear with the use of the other?"[18] Sperry cut nerves in the eyes of cats so the left eye was connected to the left hemisphere and the right eye was connected to the right hemisphere; he also cut the corpus callosum. The cats were then taught to distinguish a triangle from a square with the right eye covered.[17] Then the cats were presented the same problem with the left eye covered; the cats had no idea what they had just learned with the right eye and because of this could be taught to distinguish a square from a triangle. Depending on which eye was covered, the cats would either distinguish a square from a triangle or a triangle from a square, demonstrating that the left and right hemispheres learned and remembered two different events. This led Sperry to believe that the left and right hemispheres function separately when not connected by the corpus callosum.
  Sperry’s research with "split-brain" cats helped lead to the discovery that cutting the corpus callosum is a very effective treatment for patients who suffer from epilepsy. Initially after the patients recovered from surgery there were no signs that the surgery caused any changes to their behavior or functioning. This observation rendered the question: if the surgery had absolutely no effect on any part of the patients' normal functioning then what is the purpose of the corpus callosum? Was it simply there to keep the two sides of the brain from collapsing, as Karl Lashley jokingly put it? Sperry was asked to develop a series of tests to perform on the "split-brain" patients to determine if the surgery caused changes in the patients' functioning or not.
  Working with his graduate student Michael Gazzaniga, Sperry invited several of the "split-brain" patients to volunteer to take part in his study to determine if the surgery affected their functioning. These tests were designed to test the patients' language, vision, and motor skills. When a person views something in the left visual field (that is on the left side of their body), the information travels to the right hemisphere of the brain and vice versa. In the first series of tests, Sperry would present a word to either the left or right visual field for a short period of time. If the word was shown to the right visual field, meaning the left hemisphere would process it, then the patient could report seeing the word. If the word was shown to the left visual field, meaning the right hemisphere would process it, then the patient could not report seeing the word. This led Sperry to believe that only the left side of the brain could articulate speech. However, in a follow-up experiment, Sperry discovered that the right hemisphere does have some language abilities. In this experiment, he had the patients place their left hands in a tray full of objects located under a partition so the patient would not be able to see the objects. Then a word was shown to the patient's left visual field, which was processed by the right side of the brain. This word described one of the objects in the tray, so the patient's left hand picked up the object corresponding to the word. When participants were asked about the word and the object in their hand, they claimed they had not seen the word and had no idea why they were holding the object. The right side of the brain had recognized the word and told the left hand to pick it up, but because the right side of the brain cannot speak and the left side of the brain had not seen the word, the patient could not articulate what they had seen.
  In another series of experiments further examining the lateralization of language in the left and right hemispheres, Sperry presented one object to the left visual field and a different object to the right visual field of the "split-brain" patients. The patient’s left hand was put under a partition and then the patient was asked to draw with their left hand what they had been shown. The patients would draw what they had seen in their left visual field, but when asked what they had drawn would describe what had been shown to their right visual field. These tests proved that when the corpus callosum is severed, it breaks the connection between the left and right hemispheres, making them unable to communicate with each other. Not only are they unable to communicate with each other, but also without the corpus callosum connecting them one hemisphere has no idea that the other hemisphere even exists. There was even evidence of this outside the laboratory when some of the patients reported that, "while their left hand was unbuttoning their shirt, the right hand would follow along behind and button it again."[19] These experiments were beneficial to numerous people in many different ways.
  In his words, each hemisphere is:
indeed a conscious system in its own right, perceiving, thinking, remembering, reasoning, willing, and emoting, all at a characteristically human level, and . . . both the left and the right hemisphere may be conscious simultaneously in different, even in mutually conflicting, mental experiences that run along in parallel
— Roger Wolcott Sperry, 1974

The curse of knowledge is a cognitive bias that occurs when an individual, communicating with other individuals, unknowingly assumes that the others have the background to understand.[1] For example, in a classroom setting, teachers have difficulty teaching novices because they cannot put themselves in the position of the student. A brilliant professor might no longer remember the difficulties that a young student encounters when learning a new subject. This curse of knowledge also explains the danger behind thinking about student learning based on what appears best to faculty members, as opposed to what has been verified with students.[2]

Michael Gazzaniga

      Dr. Gazzaniga has led pioneering studies in learning and understanding split brained patients and how their brains work.[3] He has performed numerous studies and done large amounts of research on split brain patients to provide a higher quality understanding into the lives of those affected by this rare phenomenon. He has studied how people who have the two halves of the brain separated function in comparison to those who do not. Dr. Gazzaniga has looked into what bodily functions are controlled by each half of the brain. He has looked at what split brained patients are able to do as a result of their condition such as the ability to draw two different objects with each hand, an ability that a person with a non split brain is unable to do. They study how those with split brain act emotionally and physically in comparison to those who do not have a split brain. Through Gazzaniga’s studies a much greater understanding of the split brain phenomenon has been brought to other physiologists as well as the general population of the world.[4][5]

For more than a century, we’ve known that the brain’s two sides serve differing functions. Accidents, strokes, and tumors in the left hemisphere generally impair activities of the rational, verbal, nonintuitive mind, such as reading, writing, speaking, arithmetic reasoning, and understanding. Similar lesions in the right hemisphere seldom have such dramatic effects.
By 1960 the left hemisphere (or “left brain”) was well accepted as the dominant or major hemisphere, and its quieter companion as the subordinate or minor hemisphere. The left hemisphere is rather like the moon’s facing side—the one easiest to observe and study. It talks to us. The other side is there, of course, but hidden.
When surgeons first separated the brain’s hemispheres as a treatment for severe epilepsy, they effectively created a small population of what have been called the most fascinating people on earth—split-brain people who are literally of two minds. The peculiar nature of our visual wiring enables researchers to send information to either the patients’s left or right brain by having the patient stare at a spot and then flashing a stimulus to the right or left of it. (They could do this with you, too, but in your intact brain the telltale hemisphere that received the information would instantly call the news to its partner across the valley. Split-brain surgery severs the phone cables—the corpus collosum—across the valley.) Finally, the researchers quiz each hemisphere separately.
In an early experiment, psychologist Michael Gazzaniga asked split-brain patients to stare at a dot as he flashed HE•ART. Thus HE appeared in their left visual field (which transmits to the right brain) and ART in the right field (which transmits to the left brain). When he then asked them what they had seen, the patients said they saw ART and so were startled when their left hands (controlled by the right brain) pointed to HE. Given an opportunity to express itself, each hemisphere reported only what it had seen. The left hand intuitively knew what it could not verbally report.

Similarly, when a picture of a spoon was flashed to their right brain, the patients could not say what they saw. But when asked to identify what they had seen by feeling an assortment of hidden objects with their left hands, they readily selected the spoon. If the experimenter said, “Right!” the patient might reply, “What? Right? How could I possibly pick out the right object when I don’t know what I saw?” It is, of course, the left brain doing the talking here, bewildered by what it’s nonverbal right brain quietly knows.
These experiments demonstrate that the right brain understands simple requests and easily perceives objects. In fact, the right brain is superior to the left at copying drawings, recognizing faces, perceiving differences, sensing and expressing emotion.
Although the left brain is adept at literal interpretations of language, the right brain excels in making subtle inferences. If “primed” with the flashed word foot, the left brain will be especially quick to then recognize the closely associated word heel. But if primed with foot, cry, and glass, the right brain will more quickly recognize another word that is distantly related to all three: cut. And if given a verbal problem—what word goes with high, district, and house?—the right brain more quickly than the left recognizes that the solution is school. As one patient explained after suffering right-brain stroke damage, “I understand words, but I’m missing the subtleties.” Thus, the right brain helps us modulate our speech to make meaning clear—as when we ask “What’s that in the road ahead?” instead of “What’s that in the road, a head?”
Some split-brain surgery patients have temporarily been bothered by the unruly independence of their left hand, which might unbutton a shirt while the right hand buttoned it.
Some split-brain surgery patients have temporarily been bothered by the unruly independence of their left hand, which might unbutton a shirt while the right hand buttoned it, or put groceries back on the shelf after the right hand put them in the cart. It was as if each hemisphere was thinking “I’ve half a mind to wear my green (blue) shirt today.” Indeed, said Nobel laureate psychologist Roger Sperry, split-brain surgery leaves people “with two separate minds.” (Reading these reports, I imagine a split-brain person enjoying a solitary game of “rock, paper, and scissors”—left hand versus right.)
When the two minds are at odds, the left brain acts as the brain’s press agent, doing mental gymnastics to rationalize unexplained action. If the right brain commands an action, the left brain will intuitively justify it. If the right brain is commanded to laugh, the patient will respond with laughter. The left brain, when asked why the laughter, will rationalize, perhaps pointing to the “funny research.” If a patient follows an order sent to the right brain (“Walk”), the left brain will offer a ready explanation (“I’m going into the house to get a Coke”). Michael Gazzaniga concludes that the left brain is an “interpreter” that instantly constructs theories to justify our behavior. We humans have a quick facility for constructing meaning.
Most of the body’s paired organs—kidneys, lungs, breasts—perform identical functions, providing a backup should one side fail. Not so the brain’s two halves. They are a biological odd couple, serving differing functions, each seemingly with a mind of its own. From simply looking at the similarly shaped hemispheres, who would suppose that they contribute uniquely to the harmony of the whole?
And not even Freud (who didn’t anticipate the cool intelligence of the hidden mind) could have supposed that our brains are humming with so much resourceful activity outside our conscious awareness, and that our interpretive left brain, grasping at straws, can so speedily intuit false explanations for our behavior. Beneath the surface there is much intelligence, and above the surface there is much self-delusion.
