“With few exceptions, the bulk of the collected lesion evidence up through the 1950s into the early '60s converged to support the picture of a leading, more highly evolved and intellectual left hemisphere and a relatively retarded right hemisphere that by contrast, in the typical righthander brain, is not only mute and agraphic but also dyslexic, word-deaf and apraxic, and lacking generally in higher cognitive function.”

“When the brain is whole, the unified consciousness of the left and right hemispheres adds up to more than the individual properties of the separate hemispheres.”

New Mindset on Consciousness (1987)

“There is no doubt that right-hemisphere intuitive thinking may perceive patterns and connections too difficult for the left hemisphere; but it may also detect patterns where none exist. Skeptical and critical thinking is not a hallmark of the right hemisphere. And unalloyed right-hemisphere doctrines, particularly when they are invented during new and trying circumstances, may be erroneous or paranoid.”

“Sooner or later, if human society is to evolve—indeed, if it is to survive—we must match our lives to our new knowledge. For too long, the Two Cultures—the esthetic, feeling humanities and cool, analytical science—have functioned independently, like the right and left hemispheres of a split-brain patient. We have been the victims of our collective divided consciousness.”

“Unlike other aspects of cognitive function, emotions have never been readily confinable to one hemisphere.”

Nobel lecture (1981)
Context: Unlike other aspects of cognitive function, emotions have never been readily confinable to one hemisphere. Though generated by lateralized input, the emotional effects tend to spread rapidly to involve both hemispheres, apparently through crossed fiber systems in the undivided brain stem.

“Left hemisphere industrialism has blinded the Chinese to the effects of our alphabet: pattern recognition is in the right hemisphere.”

“Earlier contentions that the right hemisphere is not even conscious largely gave way by the mid seventies to an intermediate position conceding that the mute hemisphere may be conscious at some lower elemental levels, but claiming that it lacks the higher, reflective, self-conscious kind of inner awareness that is special to the human mind and is needed, so it is said, to qualify the right conscious system as a "self' or "person". Self awareness in particular is reported, on the basis of mirror tests mainly, to be a predominantly human attribute and is rated by developmental as well as by evolutionary standards to be a highly advanced phase of conscious awareness.”

“David Galin, among other researchers, has pointed out that teachers have three main tasks: first, to train both hemispheres — not only the verbal, symbolic, logical left hemisphere, which has always been trained in the traditional education, but also the relational, holistic right hemisphere, which is largely neglected in today's schools; second, to train students to use the cognitive style suited to the tasks at hand; and third, to train students to be able to bring both styles — both hemispheres — to bear on a problem in an integrated manner.
When teachers can pair the complementary modes or fit one mode to the appropriate task, teaching and learning will become a much more precise process. Ultimately, the goal will be to develop both halves of the brain. Both modes are necessary for full human functioning and both are necessary for creative work of all kinds, whether writing or painting, developing a new theory in physics, or dealing with environmental problems.”

“You', the ego, live in your left brain. When we say that man is the only creature who spends 99 per cent of his time inside his own head, we mean, in fact, inside his left cerebral hemisphere. And in the basement of the left hemisphere is the library full of filing cabinets -- the stuffy room that we mistake for reality.”

“The next phase of the work was when Joseph LeDoux and I came up with the idea of the interpreter. Twenty-five years into studying these patients we finally got around to asking the patients, "Why did you do that?" after they had a response with the left hand that was being governed by the separated, silent, speechless right hemisphere. We began to understand that the left hemisphere "made up" a story as to why the patient did what he/she did, and in that moment we began to see the cardinal feature of the left hemisphere: the ability to interpret actions generated outside its realm of conscious awareness.”

Michael S. Gazzaniga (1939) American neuroscientist
