Left Hemisphere Quotes & Sayings

There is another connection between infancy and dreams: both are followed by amnesia. When we emerge from either state, we have great difficulty remembering what we have experienced. In both cases, I would suggest, the left hemisphere of the neocortex, which is responsible for analytic
recollection, has been functioning ineffectively. — Carl Sagan

The main theme to emerge ... is that there appear to be two modes of thinking, verbal and nonverbal, represented rather separately in left and right hemispheres respectively and that our education system, as well as science in general, tends to neglect the nonverbal form of intellect. What it comes down to is that modern society discriminates against the right hemisphere. — Roger Wolcott Sperry

This is the left hemisphere confabulating. It does this for all of us, every waking moment. It edits our conscious experiences, makes them comprehensible and palatable. It's the brain's spin-doctor. — Paul Broks

When you read a book, you generate beta waves irrespective of the book's content. But if you look up from it, and start watching TV - it doesn't matter what the content of the program is - the beta waves disappear and you start processing alpha and theta waves. These are the same waves that you generate during meditation. Reading is primarily left hemisphere and watching television is primarily right hemisphere. Now how could that not have a major effect on our culture? — Leonard Shlain

Sacred play is anything that takes you into that right hemisphere of your brain. It turns out that this move away from left to the right hemisphere, that sense of expansiveness and everything, can be accomplished through unusual rhythmic action, or any action that requires so much attention away from words that you cannot think in words. — Martha Beck

Some people can never learn to ski powder snow without exerting tremendous effort and strength because they allow their rational, left-brain hemisphere to control the entire situation. — Dolores LaChapelle

As the language areas of the left hemisphere enter their sensitive period during the middle of the second year of life, grammatical language in the left integrates with the interpersonal and prosodic elements of communication already well developed in the right. As the cortical language centers mature, words are joined together to make sentences and can be used to express increasingly complex ideas flavored with emotion. As the frontal cortex continues to expand and connect with more neural networks, memory improves and a sense of time slowly emerges and autobiographical memory begins to connect the self with places and events, within and across time. The emerging narratives begin to organize the nascent sense of self and become the bedrock of our sense of self in interpersonal and physical space — Louis Cozolino

We have to be wary of our brains. They make our decisions before we make them. They lead us to still waters. They renounceth free will. And it gets weirder: If you slice a brain down the middle, the left hemisphere and the right hemisphere will operate self-sufficiently and not know what the other is doing. — E.L. Doctorow

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. — Carl Sagan

Some evidence suggests the left-handers are more likely to have problems with such left-hemisphere functions as reading, writing, speaking and arithmetic; and to be more adept at such right -hemisphere functions as imagination, pattern recognition and general creativity. — Carl Sagan

Major scientific insights are characteristically intuitive, and equally characteristically described in scientific papers by linear analytical arguments. There is no anomaly in this: it is, rather, just as it should be. The creative act has major right-hemisphere components. But arguments on the
validity of the result are largely left-hemisphere functions. — Carl Sagan

If the left hemisphere of the brain goes on dominating you, you will live a successful life - so successful that by the time you are forty you will have ulcers; by the time you are forty-five, you will have had at least one or two heart attacks. By the time you are fifty you will be almost dead - but successfully dead! You may become a great scientist, but you will never become a great being. You may accumulate enough wealth, but you will lose all that is of worth. You may conquer the whole world like an Alexander, but your own inner territory will remain unconquered. — Osho

patients with aphasia and left-hemisphere lesions, says they have lost 'abstract' and 'propositional' thought - and compares them with dogs (or, rather, he compares dogs to patients with aphasia). — Oliver Sacks

When split-brain patients fabricate verbal (left hemisphere based) explanations for behaviors that were produced by the right hemisphere, the left hemisphere is generating explanations of behaviors produced by nonconscious systems and does so in the maintenance of a sense of self. That is, our behavior is an important way we come to know who we are. This is the essence of Gazzaniga's interpreter theory of consciousness (see Chapter 6). — Joseph E. Ledoux

In a way, science might be described as paranoid thinking applied to Nature: we are looking for natural conspiracies, for connections among apparently disparate data. Our objective is to abstract patterns from Nature (right-hemisphere thinking), but many proposed patterns do not in fact correspond to the
data. Thus all proposed patterns must be subjected to the sieve of critical analysis (left-hemisphere thinking). — Carl Sagan

The scientific study of the relationship between brain and mind began in 1861, when Broca, in France, found that specific difficulties in the expressive use of speech, aphasia, consistently followed damage to a particular portion of the left hemisphere of the brain. — Oliver Sacks

The left side of my brain had been shut down like a damaged section of a spinship being sealed off, airtight doors leaving the doomed compartments open to vacuum. I could still think. Control of the right side of my body soon returned. Only the language centers had been damaged beyond simple repair. The marvelous organic computer wedged in my skull had dumped its language content like a flawed program. The right hemisphere was not without some language - but only the most emotionally charged units of communication could lodge in that affective hemisphere; my vocabulary was now down to nine words. (This, I learned later, was exceptional, many victims of CVAs retain only two or three.) For the record, here is my entire vocabulary of manageable words: fuck, shit, piss, cunt, goddamn, motherfucker, asshole, peepee, and poopoo; — Dan Simmons

The left hemisphere is more sophisticated and specialized, a very late outgrowth of the primate, and especially the hominid, brain. On the other hand, it is the right hemisphere which controls the crucial powers of recognizing reality which every living creature must have in order to survive. — Oliver Sacks

The left hemisphere is very interested in language; it communicates in words, it has a past, a present, and a future; it has a time component and it's all about details. The right hemisphere is more about the right now-right here experience where everything is an enormous collage of all the sensory systems flooding into our brains. — Jill Bolte Taylor

When Western people train the mind, the focus is generally on the left hemisphere of the cortex, which is the portion of the brainthat is concerned with words and numbers. We enhance the logical, bounded, linear functions of the mind. In the East, exercises of this sort are for the purpose of getting in tune with the unconscious
to get rid of boundaries, not to create them. — Edward T. Hall

Don't leave home without your left hemisphere — Michael Gazzaniga

In such cases, each hemisphere might well have its own beliefs. Consider what this says about the dogma - widely held under Christianity and Islam - that a person's salvation depends upon her believing the right doctrine about God. If a split-brain patient's left hemisphere accepts the divinity of Jesus, but the right doesn't, are we to imagine that she now harbors two immortal souls, one destined for the company of angels and the other for an eternity in hellfire? — Sam Harris

The right hemisphere controls sensory attention and body image; the left hemisphere controls skilled movements and some aspects of language. — Michio Kaku

It's likely that taboo words are stored in the right hemisphere of the brain. Massive left hemisphere strokes or the entire surgical removal of the left hemisphere can leave people with no articulate speech other than the ability to swear, spout cliches and song lyrics. — Steven Pinker

It is as if one hemisphere of your brain is perceiving the world as reflected in a mirror. Through a mirror. See? So left becomes right, and all that that implies. And we don't know yet what that does imply, to see the world reversed like that. Topologically speaking, a left-hand glove is a right-hand glove pulled through infinity. — Philip K. Dick

If my brain were surgically divided by callosotomy tomorrow, this would create at least two independent conscious minds, both of which would be psychologically continuous with the person who is now writing this paragraph. If my linguistic abilities happened to be distributed across both hemispheres, each of these minds might remember having written this sentence. The question of whether I would land in the left hemisphere or the right doesn't make sense - being based, as it is, on the illusion that there is a self bobbing on the stream of consciousness — Sam Harris

As Gazzaniga put it, these findings all suggest that the interpretive mechanism of the left hemisphere is always hard at work, seeking the meaning of events. It is constantly looking for order and reasons, even when there is none - which leads it continually to make mistakes. — David Eagleman

Via our left hemisphere language centers, our mind speaks to us constantly, a phenomenon I refer to as "brain chatter." It is that voice reminding you to pick up bananas on your way home and that calculating intelligence that knows when you have to do your laundry. There is vast individual variation in the speed at which our minds function. For some, our dialogue of brain chatter runs so fast that we can barely keep up with what we are thinking. Others of us think in language so slowly that it takes a long time for us to comprehend. Still others of us have a problem retaining our focus and concentration long enough to act on our thoughts. These variations in normal processing stem back to our brain cells and how each brain is intrinsically wired. — Jill Bolte Taylor

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. — Roger Wolcott Sperry

THE SPLIT-BRAIN PARADOX One way in which this picture, based on the corporate hierarchy of a company, deviates from the actual structure of the brain can be seen in the curious case of split-brain patients. One unusual feature of the brain is that it has two nearly identical halves, or hemispheres, the left and right. Scientists have long wondered why the brain has this unnecessary redundancy, since the brain can operate even if one entire hemisphere is completely removed. No normal corporate hierarchy has this strange feature. Furthermore, if each hemisphere has consciousness, does this mean that we have two separate centers of consciousness inside one skull? — Michio Kaku

The White Hand did not fry all the brain. He fried some
from the right hemisphere and some from the left. The
remaining brain, The White Hand wrapped in tin foil,
carefully. Tomorrow is, after all, another day, and food should be kept
in storage so it won't go bad. — Siberian Hellhole By Michael Mulvihill

You begin by engaging the left hemisphere of the brain with the overall shape, the basic structure of the painting, and then eventually you engage with the colour, with the mood of the painting and then you are entering the activities of the right hemisphere - and it is in the right hemisphere that ideas of space are born, the realization that you are seeing space. — Guido Molinari

For many of us, once we have made a decision, then we are attached to that decision forever. I have found that often the last thing a really dominating left hemisphere wants is to share its limited cranial space with an open-minded right counterpart! — Jill Bolte Taylor

In the fifteenth century the Pope deeded the entire western hemisphere to Spain and Portugal and nobody paid the slightest attention to the fact that the real estate was already occupied by several million Indians with their own laws, customs, and notions of property rights. His grant deed was pretty effective, too. Take a look at a western hemisphere map sometime and notice where Spanish is spoken and where Portuguese is spoken - and see how much land the Indians have left. — Robert A. Heinlein

The left hemisphere seems to feel quite defensive-in a strange way insecure-about the right hemisphere; and, if this is so, verbal criticism of intuitive thinking becomes suspect on the ground of motive. Unfortunately, there is every reason to think that the right hemisphere has comparable misgivings -expressed nonverbally, of course- about the left. — Carl Sagan

The purpose of all of this (left hemisphere's way of choosing denial or repression over considering an anomaly) is to impose stability on behavior and to prevent vacillation because indecisiveness doesn't serve any purpose. Any decision, so long as it is probably correct, is better than no decision at all. A perpetually fickle general will never win a war. — V.S. Ramachandran
