Brain Capacity Quotes & Sayings

Grove encourages his people to work in small, autonomous work units in which everyone understands the system and their role in it. Each person contributes their knowledge, expertise and creativity. Team members are trained and motivated to produce to the best of their capacity. When crises arise, the team willingly puts in the extra time, energy and brain power to meet and beat the problems faced. — Napoleon Hill

Damn! What did Ansermet, that most faithful friend, know about Stravinsky's poverty of heart? What did he, that most devoted friend, know about Stravinsky's capacity to love? And where did he get his utter certainty that the heart is ethically superior to the brain? Are not vile acts committed as often with the heart's help as without it? Can't fanatics, with their bloody hands, boast of a high degree of "affective activity"? Will we ever be done with this imbecile sentimental Inquisition, the heart's Reign of Terror? — Milan Kundera

I'm tough, I'm pushy, I'm really loud. I used to spend a lot of time thinking about it. But we only have so much brain capacity, so if I'm spending part of my brain thinking about how I'm acting, A, I'm not spending all of my brain doing, and B, I'm not actually in that moment. — Christine Quinn

What distinguishes the various kinds of fears is the combination and amount of the raw materials involved. What ties together all instances of fear is the awareness that a threat to well-being is present or is soon very likely to occur. In short, in order to be felt as fear, components of a nonconscious defensive motivational state have to invade and become a presence98 in conscious awareness. This can only happen in organisms that have the capacity to both be aware of brain representations of internal and external events and to know in a personal, autobiographical sense that the event is happening to them - someone has to be home in the brain in order to feel fear when the defensive state knocks on the door.99 — Joseph E. Ledoux

A failing grade does not denounce a child to fail in life. An IQ is what I would call an 'inadequate question', it may state our brain capacity or tell us how smart we are, but it does not predict our future. Happy Character Traits and positive Reinforcements will help a child succeed better than a number that means nothing — Davis Carlson

The human brain has evolved the capacity to impose a narrative, complete with chronology and cause-and-effect logic, on whatever it encounters, no matter how apparently random. — Robin Marantz Henig

Structurally we should understand that one cannot think that the human brain is different from the brain of the other vertebrates. It is an important question, because we can investigate what is the difference between the brain of a mouse and ours, and of course the difference is enormous, in size and capacity. — Rodolfo Llinas

I'm an actor, and, beyond that, the thing I do most compulsively is writing. So I come at it very much from this sense of character. I get interested in people. And I feel confident in my capacity to absorb and manifest the characteristics of people. I have a real auditory hang-up for dialogue; re-creating the way people talk really is an addiction in my brain. — Edward Norton

Like most early enthusiasts, I always thought the way the Internet encouraged multitasking made users less vulnerable to manipulation, while simultaneously exploiting even more of our brain's capacity than before. Apparently not. — Douglas Rushkoff

ABNER Marsh had a mind that was not unlike his body. It was big all around, ample in size and capacity, and he crammed all sorts of things into it. It was strong as well; when Abner Marsh took something in his hand it did not easily slip away, and when he took something in his head it was not easily forgotten. He was a powerful man with a powerful brain, but body and mind shared one other trait as well: they were deliberate. Some might even say slow. Marsh did not run, he did not dance, he did not scamper or slide along; he walked with a straightforward dignified gait that nonetheless got him where he wanted to go. So it was with his mind. Abner Marsh was not quick in word or thought, but he was far from stupid; he chewed over things thoroughly, but at his own pace. — George R R Martin

it seemed entirely possible to him that religion and literature and art and music were all merely side effects of a brain structure that comes into the world ready to make language out of noise, sense out of chaos. Our capacity for imposing meaning, he thought, is programmed to unfold the way a butterfly's wings unfold when it escapes the chrysalis, ready to fly. We are biologically driven to create meaning. And if that's so, he asked himself, is the miracle diminished? It — Mary Doria Russell

It is a question of cubic capacity," said he; "a man with so large a brain must have something in it. — Arthur Conan Doyle

Success"

If you want a thing bad enough
To go out and fight for it,
Work day and night for it,
Give up your time and your peace and your sleep for it

If only desire of it
Makes you quite mad enough
Never to tire of it,
Makes you hold all other things tawdry and cheap for it

If life seems all empty and useless without it
And all that you scheme and you dream is about it,

If gladly you'll sweat for it,
Fret for it,
Plan for it,
Lose all your terror of God or man for it,

If you'll simply go after that thing that you want.
With all your capacity,
Strength and sagacity,
Faith, hope and confidence, stern pertinacity,

If neither cold poverty, famished and gaunt,
Nor sickness nor pain
Of body or brain
Can turn you away from the thing that you want,

If dogged and grim you besiege and beset it,
You'll get it! — Berton Braley

Hmm." Hell, he'd lost his voice. Maybe his capacity for thought. They were headed where his body had wanted her since the day they met. Blood surged to his groin, leaving his brain defenseless. "What's that?"

She rubbed a finger across his lower lip. "Do I make you nervous?"

She threw off his equilibrium, but he could work with that since he was trained to adapt to new and dangerous situations. He licked his lips, letting his tongue brush the finger she still pressed against him.

"I can handle you."

"Oh, sweetheart, I doubt it. — Cindy Skaggs

Gorgons and Hydras, and Chimaeras - dire stories of Celaeno and the Harpies - may reproduce themselves in the brain of superstition - but they were there before. They are transcripts, types - the archetypes are in us, and eternal. How else should the recital of that which we know in a waking sense to be false come to affect us at all? Is it that we naturally conceive terror from such objects, considered in their capacity of being able to inflict upon us bodily injury? O, least of all! These terrors are of older standing. They date beyond body - or without the body, they would have been the same ... That the kind of fear here treated is purely spiritual - that it is strong in proportion as it is objectless on earth, that it predominates in the period of our sinless infancy - are difficulties the solution of which might afford some probable insight into our ante-mundane condition, and a peep at least into the shadowland of pre-existence. — Charles Lamb

Supercomputers will achieve one human brain capacity by 2010, and personal computers will do so by about 2020. — Ray Kurzweil

The brain itself does not produce consciousness. That it is, instead, a kind of reducing valve or filter, shifting the larger, nonphysical consciousness that we possess in the non physical worlds down into a more limited capacity for the duration of our mortal lives. — Eben Alexander

This sense of the brain's remarkable plasticity, its capacity for the most striking adaptations, not least in the special (and often desperate) circumstances of neural or sensory mishap, has come to dominate my own perception of my patients and their lives. So much so, indeed, that I am sometimes moved to wonder whether it may not be necessary to redefine the very concepts of "health" and "disease," to see these in terms of the ability of the organism to create a new organization and order, one that fits its special, altered disposition and needs, rather than in the terms of a rigidly defined "norm. — Oliver Sacks

Try to inspire them to consider the power and implications of such potential. I tell them that no computer network on earth can come close to the capacity of the average human brain. This resource that each one of us has is a tremendous gift from God - the most complex organ system in the entire universe. — Ben Carson

When possible, the brain makes a behavior into a habit, which saves effort and therefore gives us more capacity to deal with complex, novel, or urgent matters. — Gretchen Rubin

Our perceptions of truth are built around what is practical, not what is true. Even the smartest human brain doesn't have the capacity for discerning true facts. That's why so many of us settle for scientific facts. It's the best we can do. — Scott Adams

Language [can] be expressed ... by movements of the hands and face just as well as by the small, sound-generating movements of the throat and mouth. Then the first criterion for language that I had learned as a student - it is spoken and heard - was wrong; and, more important, language did not depend on our ability to speak and hear but must be a more abstract capacity of the brain. It was the brain that had language, and if that capacity was blocked in one channel, it would emerge through another. — Harlan Lane

The brain is the largest data store facility to ever exist, even exceeding the storage capacity of a man's testicles (yes, if you are a man you can be proud of your pair, as they store more data than any computer). The — Bill McDowell

If you would only stop rating a child's ability by your own; and try to find out just what ability a child has, our young folks throughout this big world would show a surprisingly willing disposition to try things which would bring your approbation. A child's brain is an astonishing thing. It has, in its construction, an astounding capacity for absorbing what is brought to it; and not only to think about, but to find ways for improving it. It is today's child who, tomorrow, will, you know, laugh at our ways of doing things. — Ernest Vincent Wright

If you still use the word "I" to identify and represent yourself,
that explains why you still use less than 20% of brain capacity. — Toba Beta

By understanding and increasing just this one capacity of the human brain, an enormous amount of social change can be fostered. Failure to understand and cultivate empathy, however, could lead to a society in which no one would want to live - a cold, violent, chaotic, and terrifying war of all against all. This destructive type of culture has appeared repeatedly in various times and places in human history and still reigns in some parts of the world. And it's a culture that we could be inadvertently developing throughout America if we do not address current trends in child rearing, education, economic inequality, and our core values. — Bruce D. Perry

Based on the above analyses, it is reasonable to expect the hardware that can emulate human-brain functionality to be available for approximately one thousand dollars by around 2020. As we will discuss in chapter 4, the software that will replicate that functionality will take about a decade longer. However, the exponential growth of the price-performance, capacity, and speed of our hardware technology will continue during that period, so by 2030 it will take a village of human brains (around one thousand) to match a thousand dollars' worth of computing. By 2050, one thousand dollars of computing will exceed the processing power of all human brains on Earth. Of course, this figure includes those brains still using only biological neurons. — Ray Kurzweil

But the female mind has demonstrated a capacity for all the mental acquirements and achievements of men, and as generations ensue that capacity will be expanded; the average woman will be as well educated as the average man, and then better educated, for the dormant faculties of her brain will be stimulated to an activity that will be all the more intense and powerful because of centuries of repose. Woman will ignore precedent and startle civilization with their progress. — Nikola Tesla

When we learn to read, it's a real product of civilization and a civilized society. It affects your brain. It affects the way you think, and it gives you that capacity for self-reflection that you simply do not have without the agency of books. — Jeanette Winterson

The brain-disease model overlooks four fundamental truths: (1) our capacity to destroy one another is matched by our capacity to heal one another. Restoring relationships and community is central to restoring well-being; (2) language gives us the power to change ourselves and others by communicating our experiences, helping us to define what we know, and finding a common sense of meaning; (3) we have the ability to regulate our own physiology, including some of the so-called involuntary functions of the body and brain, through such basic activities as breathing, moving, and touching; and (4) we can change social conditions to create environments in which children and adults can feel safe and where they can thrive. — Bessel A. Van Der Kolk

Who can doubt the presence of God in the sight of men whom He has given wings?
I recall that so precisely because I've had time to consider my error. God didn't give man wings; He gave him the brain and the spirit to give himself wings. Just as He gave us the capacity to laugh when we hurt, or to struggle on when we feel like giving up.
I've come to believe that how we choose to live with pain, or injustice, or death ... is the true measure of the Divine within us. Some choose to do harm to others. Others bear up under their pain and help others to bear it. — Alan Brennert

If we are not using our brains' capacity for challenge it feels to me as though it atrophies like an unused muscle. — Philippa Perry

I have always heard that you need to give yourself a long time to unplug when you do a sabbatical. I unplugged so fast I was a little concerned that I was losing brain capacity. — John Ortberg

The injured brain cannot heal itself. Now we know that the brain has amazing powers of healing, unsuspected in the past. The brain's hardwiring cannot be changed. In fact, the line between hard and soft wiring is shifting all the time, and our ability to rewire our brains remains intact from birth to the end of life. Aging in the brain is inevitable and irreversible. To counter this outmoded belief, new techniques for keeping the brain youthful and retaining mental acuity are arising every day. The brain loses millions of cells a day, and lost brain cells cannot be replaced. In fact, the brain contains stem cells that are capable of maturing into new brain cells throughout life. How we lose or gain brain cells is a complex issue. Most of the findings are good news for everyone who is afraid of losing mental capacity as they age. — Deepak Chopra

Comparing the capacity of computers to the capacity of the human brain, I've often wondered, where does our success come from? The answer is synthesis, the ability to combine creativity and calculation, art and science, into whole that is much greater than the sum of its parts. — Garry Kasparov

Latent brain functions can be enabled by force majeure
when we are facing the weirdness of an unknown reality. — Toba Beta

[W]e may now be on the threshold of a new kind of genetic takeover. DNA replicators built 'survival machines' for themselves - the bodies of living organisms including ourselves. As part of their equipment, bodies evolved onboard computers - brains. Brains evolved the capacity to communicate with other brains by means of language and cultural traditions. But the new milieu of cultural tradition opens up new possibilities for self-replicating entities. The new replicators are not DNA and they are not clay crystals. They are patterns of information that can thrive only in brains or the artificially manufactured products of brains - books, computers, and so on. But, given that brains, books and computers exist, these new replicators, which I called memes to distinguish them from genes, can propagate themselves from brain to brain, from brain to book, from book to brain, from brain to computer, from computer to computer. — Richard Dawkins

There is a concept in cognitive psychology called the channel capacity, which refers to the amount of space in our brain for certain kinds of information. — Malcolm Gladwell

We have learned that trauma is not just an event that took place sometime in the past; it is also the imprint left by that experience on mind, brain, and body. This imprint has ongoing consequences for how the human organism manages to survive in the present. Trauma results in a fundamental reorganization of the way mind and brain manage perceptions. It changes not only how we think and what we think about, but also our very capacity to think. — Bessel A. Van Der Kolk

scientists are learning that people have more capacity for lifelong learning and brain development than they ever thought. — Carol S. Dweck

In the morning this light breasts your windowpane and, having pried your eye open like a shell, runs ahead of you, strumming its lengthy rays - like a hot-footed schoolboy running his stick along the iron grate of the park or garden - along arcades, colonnades, red-brick chimneys, saints and lions. "Depict! Depict!" it cries to you, either mistaking you for some Canaletto or Carpaccio or Guardi, or because it doesn't trust your retina's ability to retain what it makes available, not to mention your brain's capacity to absorb it. Perhaps art is simply an organism's reaction against its retentive limitations. At any rate, you obey the command and grab your camera, supplementing both your brain cells and your pupil. Should this city ever be short of cash, it can go straight to Kodak for assistance - or else tax its products savagely. By the same token, as long as this place exists, as long as winter light shines upon it, Kodak shares are the best investment. — Joseph Brodsky

I have never examined the subject of humor until now. I am surprised to find how much ground it covers. I have got its divisions and frontiers down on a piece of paper. I find it defined as a production of the brain, as the power of the brain to produce something humorous, and the capacity of percieving humor. — Mark Twain

Our minds have the incredible capacity to both alter the strength of connections among neurons, essentially rewiring them, and create entirely new pathways. (It makes a computer, which cannot create new hardware when its system crashes, seem fixed and helpless). — Susannah Cahalan

Institutions are "stable, valued, recurring patterns of behavior," as Huntington put it, the most important function of which is to facilitate collective action. Without some set of clear and relatively stable rules, human beings would have to renegotiate their interactions at every turn. Such rules are often culturally determined and vary across different societies and eras, but the capacity to create and adhere to them is genetically hard-wired into the human brain. A natural tendency to conformism helps give institutions inertia and is what has allowed human societies to achieve levels of social cooperation unmatched by any other animal species. — Anonymous

Your brain has a capacity for learning that is virtually limitless, which makes every human a potential genius. — Michael J. Gelb

We are part of nature, a product of a long evolutionary journey. To some degree, we carry the ancient oceans in our blood. ... Our brains and nervous systems did not suddenly spring into existence without long antecedents in natural history. That which we most prize as integral to our humanity - our extraordinary capacity to think on complex conceptual levels - can be traced back to the nerve network of primitive invertebrates, the ganglia of a mollusk, the spinal cord of a fish, the brain of an amphibian, and the cerebral cortex of a primate. — Murray Bookchin

Rather they are largely related to an underdeveloped brain, for the areas that govern social awareness, empathy, and related language skills are not fully operational until we're about thirty years old. Despite this neurological handicap, scientific research shows that anyone - young or old - can exercise the language and social-awareness centers of the brain in ways that will enhance their capacity to communicate more effectively with others. — Andrew B. Newberg

A lizard brain fired the gun that wounded you, but it was the combination of three brains that orchestrated the elaborate circumstances in which the trigger was pulled. Way back when, the Landlord believed a second brain would endow some of his lower life forms with the capacity for emotional connections. By adding the third brain, he probably planned on having his ... higher forms empowered with the ability to not only think before acting, but to feel regret afterwards when their actions were wrong. But that's not what happened, is it? — Richard Finney

I think any apparent contradiction in scripture is my limited capacity. Me trying to understand God is like an ant trying to understand the Internet. I don't have the brain capacity. — Rick Warren

In the last few years, we've learned that the formation and maintenance of categories have their roots in known biological processes in the brain. Neurons are living cells, and they can connect to one another in trillions of different ways. These connections don't just lead to learning - the connections are the learning. The number of possible brain states that each of us can have is so large that it exceeds the number of known particles in the universe. The implications of this are mind-boggling: Theoretically, you should be able to represent uniquely in your brain every known particle in the universe, and have excess capacity left over to organize those particles into finite categories. Your brain is just the tool for the information age. — Daniel J. Levitin

In other words, every human brain has the built-in capacity to become, over time, what we demand of it. No ability is fixed. Practice can even change the brain. — Lisa Delpit

The capacity of the brain to forsee the future has much to do with the fear of death.
For when the body is worn out and the brain is tired, the whole organism welcomes death. But it is difficult to understand how death can be welcome when you are young and strong, so that you come to regard it as a dread and terrible event. For the brain, in its immaterial way, looks into the future and conceives it a good to go on and on and on forever - not realizing that its own material would at last find the process intolerably tiresome. Not taking this into account, the brain fails to see that, being itself material and subject to change, its desires will change, and a time will come when death will be good. On a bright morning, after a good night's rest, you do not want to go to sleep. But after a hard day's work the sensation of dropping into unconsciousness is extraordinarily pleasant. — Alan W. Watts

When something horrible happens, your brain doesn't process the memories right. It stores everything
sounds, pain, smells, feelings
all mixed up. It doesn't matter if you believed it or it made sense; it gets stored. — Cherise Sinclair

What the Net seems to be doing is chipping away my capacity for concentration and contemplation. Whether I'm online or not, my mind now expects to take in information the way the Net distributes it: in a swiftly moving stream of particles. Once I was a scuba diver in the sea of words. Now I zip along the surface like a guy on a Jet Ski. — Nicholas Carr

Some wise being organized my system, and gave me my capacity, put into my heart and brain something that delights, charms, and fills me with rapture at the sound of sweet music. — Brigham Young

People lost the capacity of using their brain. It's all about the label. Not about the labels showing but subtlety of the labels. — Barbara Hulanicki

What these [personality] tests tell employers about potential employees is hard to imagine since the 'right' answer should be obvious to anyone who has ever encountered the principle of hierarchy and subordination. Do I work well with others? You bet, but never to the point where I would hesitate to inform on them for the slightest infraction. Am I capable of independent decision making? Oh yes, but I know better than to let this capacity interfere with a slavish obedience to orders ... The real function of these tests, I decide, is to convey information not to the employer but to the potential employee, and the information being conveyed is always: You will have no secrets from us. We don't just want your muscles and that portion of your brain that is directly connected to them; we want your innermost self. — Barbara Ehrenreich

The ultimate creative capacity of the brain may be, for all practical purposes, infinite. — George Leonard

Dogma is a defence against the brain's capacity for free thought based on the fear that such thought might lead to a scary place. — Joe Blow

Enlightenment of your brain means the limited capacity of your brain has to become unlimited in its capacity to realize God. — Nirmala Srivastava

[Speaking to a group of wealthy New Yorkers]
A million years ago, the cave man, without tools, with small brain, and with nothing but the strength of his body, managed to feed his wife and children, so that through him the race survived. You on the other hand, armed with all the modern means of production, multiplying the productive capacity of the cave man a million times - you are incompetents and muddlers, you are unable to secure to millions even the paltry amount of bread that would sustain their physical life. You have mismanaged the world, and it shall be taken from you. — Jack London

If we're talking about brain performance, the best predictor of brain speed is aerobic capacity - how well you can run up a hill is very strongly correlated with brain speed and cognitive shifting ability, — Hal Elrod

The different political systems, religions and social habits demonstrate that the same brain can be tuned in different manners. But the tuning capacity is limited. We can never feel as a jaguar, for example. We can imagine a man who believes or who intends to be a jaguar, but to intend is not the same as to be. We can have other ideologies, but we will continue restricted by the nature of our brain and of our body. — Rodolfo Llinas

I have only a second rate brain, but I think I have a capacity for action. — Theodore Roosevelt

The human brain has a marvelous capacity to screen and sort experience, protecting itself against the unbearable. — Rick Yancey

The human brain is a marvel. A mere 20 watts of energy are required to power the 22 billion neurons in a brain that's roughly the size of a grapefruit. To field a conventional computer with comparable cognitive capacity would require gigawatts of electricity and a machine the size of a football field. — John E. Kelly III

The worst period I ever went through at work," a friend confides, "was when the company was restructuring and people were being 'disappeared' daily, followed by lying memos that they were leaving 'for personal reasons.' No one could focus while that fear was in the air. No real work got done." Small wonder. The greater the anxiety we feel, the more impaired is the brain's cognitive efficiency. In this zone of mental misery, distracting thoughts hijack our attention and squeeze our cognitive resources. Because high anxiety shrinks the space available to our attention, it undermines our very capacity to take in new information, let alone generate fresh ideas. Near-panic is the enemy of learning and creativity. — Daniel Goleman

Children are trained to think linearly instead of imaginatively; they are taught to read slowly and carefully, and are discouraged from daydreaming. They are trained to reduce the use and capacity of their brain. — Tony Buzan

People followed him not because of his idea of a changed America. People followed him because of their idea of a changed America. The part of the brain that influences our behavior and decisions does not have the capacity for language. We have trouble saying clearly, in emotional terms, why we do what we do, and offer rationalizations that, though valid and true, are not powerful enough to inspire others. — Simon Sinek

Two brains are better than one. You've twice the brain capacity and you have two sets of experiences and genes to bring to any challenge. — Philippa Perry

At still higher doses psilocybin triggers this activity in the language-forming capacity of the brain that manifests as song and vision. Psilocybin may have synergized the emergence of higher forms of psychic organization out of primitive protohuman animals. It can be seen as a kind of evolutionary enzyme, or evolutionary catalyst. — Terence McKenna

Possibly, over the course of time, the brain capacity of homo sapiens will have made such great progress, that complications as contained in this game can be fathomed instantly with a shrug and a smile. Then, not only will the game of chess have ceased to exist, but also will the remembrance of frequently missed objectives elicit pity, as a reaction to the shortcomings of a lower organized form of life. — Lodewijk Prins

What constrains or enables the capacity of human beings to work in groups is not so much the technology, but rather the capacity of the human brain to have and monitor social interactions. — Nicholas A. Christakis

The intelligence we will create from the reverse-engineering of the brain will have access to its own source code and will be able to rapidly improve itself in an accelerating iterative design cycle. Although there is considerable plasticity in the biological human brain, as we have seen, it does have a relatively fixed architecture, which cannot be significantly modified, as well as a limited capacity. We are unable to increase its 300 million pattern recognizers to, say, 400 million unless we do so nonbiologically. Once we can achieve that, there will be no reason to stop at a particular level of capability. We can go on to make it a billion pattern recognizers, or a trillion. — Ray Kurzweil

Morality is not a large, constructed *thing* you have or have not, but simply a capacity. Something you carry with you in your brain and in your hands. — Barbara Kingsolver

The human brain is incredible in its capacity to heal and rewire itself. The human brain can be shaped and trained to be more resilient, calm, compassionate and alert - we can condition ourselves to be successful. Through mindfulness meditation, we can literally re-wire our brains through new experiences, which modify our neural network and our neural chemistry. Mindfulness also enhances gamma synchrony and improves the function of the human brain. — Christopher Dines

A person cannot direct his emotional life in the way he bids his motor system to reach for a cup. He cannot will himself to want the right thing or to love the right person or to be happy after a disappointment, or even to be happy in happy times. People lack this capacity not through a deficiency of discipline but because the jurisdiction of will is limited to the latest brain and to those functions within its purview. Emotional life can be influenced, but it cannot be commanded. — Thomas Lewis

The storage capacity of the average human brain is two-hundred and fifty-six exabytes. However, the average adult human only uses approximately one billionth of that storage space effectively. This means my knowledge capacity is approximately three thousand trillion times that of your average human. — Michael Monroe

The brain is not a shoebox that 'gets full,' but rather a muscle that expands its capacity with increased use. The more you know, the more you can know. — Douglas Wilson

The human brain is like a freight car, guaranteed to carry a certain capacity but often running empty. — Lorraine Gokul

I don't think it had ever occurred to me that man's supremacy is not primarily due to his brain, as most of the books would have one think. It is due to the brain's capacity to make use of the information conveyed to it by a narrow band of visible light rays. His civilization, all that he had achieved or might achieve, hung upon his ability to perceive that range of vibrations from red to violet. Without that, he was lost. — John Wyndham

It is the large brain capacity which allows man to live as a human being, enjoy taxes, canned salmon, television, and the atomic bomb. — Gustav Heinrich Ralph Von Koenigswald

The neurons that do expire are the ones that made imitation possible. When you are capable of skillful imitation, the sweep of choices before you is too large; but when your brain loses its spare capacity, and along with it some agility, some joy in winging it, and the ambition to do things that don't suit it, then you finally have to settle down to do well the few things that your brain really can do well
the rest no longer seems pressing and distracting, because it is now permanently out of reach. The feeling that you are stupider than you were is what finally interests you in the really complex subjects of life: in change, in experience, in the ways other people have adjusted to disappointment and narrowed ability. You realize that you are no prodigy, your shoulders relax, and you begin to look around you, seeing local color unrivaled by blue glows of algebra and abstraction. — Nicholson Baker

This moment of lucidity does not last long. But it serves as the punishment for your sins, a Promethean entrails-pecking moment, crouching half-horse half-man, with the knowledge that you cannot appreciate the destination without knowing the starting point; you cannot revel in the simplicity unless you remember the alternatives.
And that's not the worst of your revelation. You realize that the next time you return here, with your thick horse brain, you won't have the capacity to ask to become a human again. You won't understand what a human is. Your choice to slide down the intelligence ladder is irreversible. And just before you lose your final human faculties, you painfully ponder what magnificent extraterrestrial creature, enthralled with the idea of finding a simpler life, chose in the last round to become a human. — David Eagleman
