Brain What System Quotes & Sayings

Though it accounts for only 2 percent of the body's mass, it uses up a fifth of all the oxygen we breathe, and it's where a quarter of all our glucose gets burned. The brain is the most energetically expensive piece of equipment in our body, and has been ruthlessly honed by natural selection to be efficient at the tasks for which it evolved. One might say that the whole point of our nervous system, from the sensory organs that feed information to the glob of neurons that interprets it, is to develop a sense of what is happening in the present and what will happen in the future, so that we can respond in the best possible way. Strip away the emotions, the philosophizing, the neuroses, and the dreams, and our brains, in the most reductive sense, are fundamentally prediction and planning machines. — Joshua Foer

The brain controls pain. It controls fear. Sleep. Empathy. Hunger. Everything we associate with the heart or the soul or the nervous system is actually controlled by the brain. Everything. What if you could control it? — Dennis Lehane

He had found a Nutri-Matic machine which had provided him with a plastic cup filled with a liquid that was almost, but not quite, entirely unlike tea. The way it functioned was very interesting. When the Drink button was pressed it made an instant but highly detailed examination of the subject's taste buds, a spectroscopic analysis of the subject's metabolism and then sent tiny experimental signals down the neural pathways to the taste centers of the subject's brain to see what was likely to go down well. However, no one knew quiet why it did this because it invariable delivered a cupful of liquid that was almost, but not quite, entirely unlike tea. The Nutri-Matic was designed and manufactured by the Sirius Cybernetics Corporation whose complaint department now covers all the major landmasses of the first three planets in the Sirius Tau Star system. — Douglas Adams

the job of the brain is to constantly monitor and evaluate what is going on within and around us. These evaluations are transmitted by chemical messages in the bloodstream and electrical messages in our nerves, causing subtle or dramatic changes throughout the body and brain. These shifts usually occur entirely without conscious input or awareness: The subcortical regions of the brain are astoundingly efficient in regulating our breathing, heartbeat, digestion, hormone secretion, and immune system. However, these systems can become overwhelmed if we are challenged by an ongoing threat, or even the perception of threat. This accounts for the wide array of physical problems researchers have documented in traumatized people. Yet our conscious self also plays a vital role in maintaining our inner equilibrium: We need to register and act on our physical sensations to keep our bodies safe. — Bessel A. Van Der Kolk

We are a country that lacks riches. The Jewish brain, that's what we have. Everything that we've had and will have in this country is the direct and clear product of higher education. If we harm this system, we will drastically decline and cease to exist. — Aaron Ciechanover

The heart is a muscle. You 'know' in your limbic system. The seat of instinct. The mammalian brain. Deeper, wider, beyond logic. That is where advertising works, not in the upstart cortex. What we think of as 'mind' is only a sort of jumped-up gland, piggybacking on the reptilian brainstem and the older, mammalian mind, but our culture tricks us into recognizing it as all of consciousness. The mammalian spreads continent-wide beneath it, mute and muscular, attending its ancient agenda. And makes it buy things. — William Gibson

we have a plastic brain that changes in response to our experience. It bears repeating: The brain doesn't tell us what to do; it is part of a system in which our life experience teaches our brain what to do. So you can practice mindfulness, will power, overcoming procrastination, and other healthy new skills with the confidence that you are changing your brain. Each day's practice does some good, and if you slip and fall off your diet or exercise program or mindfulness practice, all that you have learned before is not undone; it's still there in your brain waiting for you to get back in the saddle. — Richard O'Connor

Fear ... " I uncrossed her arms and linked my fingers with hers. "Is what makes us feel alive. Fear causes our blood vessels to constrict, and then the amygdala, a tiny almond shaped part of our brain, sends signals to our nervous system. The signal says run or fight. — Rachel Van Dyken

Everyone else new you ever meet, and this continues through life, is stronger than you are, knows the system better and sees right through to the back of your brain and finds what they see to be wholly inadequate. Everyone you encounter carries, as it were, a huge club behind their back, while all you hold behind yours is a weedy cotton-bud. — Stephen Fry

Here's what I think: when you're born, you're assigned a brain like you're assigned a desk, a nice desk, with plenty of pigeonholes and drawers and secret compartments. At the start, it's empty, and then you spend your life filling it up. You're the only one who understands the filing system, you amass some clutter, sure, but somehow it works: you're asked the capital of Oregon, and you say Salem; you want to remember your first-grade teacher's name, and there it is, Miss Fox. Then suddenly you're old, and though everything's still in your brain, it's crammed so tight that when you try to remember the name of the guy who does the upkeep on your lawn, your first childhood crush comes fluttering out, or the persistent smell of tomato soup in a certain Des Moines neighborhood. — Elizabeth McCracken

If a stranger saying we are "dependable" activates the reward system, imagine what praise from a boss, a parent, or even an unaccomplished slightly older graduate student will do. Of course, we all know that praise is a good thing, as long as it isn't too unconditional, but until very recently, we had no idea that praise taps into the same reinforcement system in the brain that enables cheese to help rats learn to solve mazes. And positive social regard is a renewable resource. Rather than having less of something after using it, when we let others know we value them, both parties have more. — Matthew D. Lieberman

What Positive Input Does Promotes overall balance, or homeostasis. Moves easily through the system, without obstruction or blockages. Generates new neural pathways. Promotes the production of new brain cells. Improves gene expression. Allows every cell to function normally, without anomalies or aberrant behavior. Supports the immune system, increasing resistance to disease. Counteracts the effects over time of entropy and aging. Increases a sense of wellbeing: The person feels healthy, vibrant, and alive. — Deepak Chopra

Everything you see is filtered through your visual system (imperfect) and your brain (also imperfect, despite what your mom told you). Witness testimony is the worst kind of evidence in science. — Seth Shostak

originally is like a little empty attic, and you have to stock it with such furniture as you choose. A fool takes in all the lumber of every sort that he comes across, so that the knowledge which might be useful to him gets crowded out, or at best is jumbled up with a lot of other things, so that he has a difficulty in laying his hands upon it. Now the skilful workman is very careful indeed as to what he takes into his brain-attic. He will have nothing but the tools which may help him in doing his work, but of these he has a large assortment, and all in the most perfect order. It is a mistake to think that that little room has elastic walls and can distend to any extent. Depend upon it there comes a time when for every addition of knowledge you forget something that you knew before. It is of the highest importance, therefore, not to have useless facts elbowing out the useful ones." "But the Solar System!" I protested. "What the deuce is it to me?" he interrupted impatiently: "you — Arthur Conan Doyle

A powerful AI system tasked with ensuring your safety might imprison you at home. If you asked for happiness, it might hook you up to a life support and ceaselessly stimulate your brain's pleasure centers. If you don't provide the AI with a very big library of preferred behaviors or an ironclad means for it to deduce what behavior you prefer, you'll be stuck with whatever it comes up with. And since it's a highly complex system, you may never understand it well enough to make sure you've got it right. — James Barrat

What is the matter with these people, these people who won't stop fighting, won't stop hurting each other long enough to see that a body is a thing of beauty, is a miracle of rivers and oceans and islands and continents contained within itself? That the brain is divided into two hemispheres, each symmetrical, each perfect, each with its own system of waterways. These people of war should be shown an x-ray of an intraparenchymal hemorrhage, of a hemorrhage in an eighteen-year-old girl's brain, a girl named Ivy. Take a look at that, people of war. See, you should not hurt each other, and this is why. Without you ever even trying, this is what can happen to your body, your beautiful body, and your brain, your beautiful symmetrical brain, and your heart, and your soul. — Alison McGhee

Artificial intelligence is based on the assumption that the mind can be described as some kind of formal system manipulating symbols that stand for things in the world. Thus it doesn't matter what the brain is made of, or what it uses for tokens in the great game of thinking. Using an equivalent set of tokens and rules, we can do thinking with a digital computer, just as we can play chess using cups, salt and pepper shakers, knives, forks, and spoons. Using the right software, one system (the mind) can be mapped onto the other (the computer). — George Johnson

The most flattering spin I can put on this phase of paradoxes and metaphysical tangles is that I was smart enough, at age fourteen, to destroy any fledgling hypothesis I came up with. A tentative explanation, theory, or formulation would pop up in my brain only to be attacked by what amounted to a kind of logical immune system, bent on eliminating all that was weak or defective. Which is to say that my mind had become a scene of furious predation, littered with the half-eaten corpses of vast theories and brilliant syntheses. — Barbara Ehrenreich

In front of her, Samuel Rain's spectacles shimmered, and she belatedly realized they weren't old-fashioned at all, but tools to allow him to see to a microcellular level. "Imbeciles." The engineer shut the interface panel, nodded at Vasic to close the protective carapace. "Stealing my work and thinking they know what to do with it. Like monkeys deciding to program a computronic system."
"Can you fix it?" Vasic asked.
"No, I'm brain damaged." With that, he put away the tool, snapped the toolbox shut, and hefted it. "Come back tomorrow."
Ivy stared after the engineer, hope a tight, hard knot in her chest. "He's either mad or brilliant."
"There's often only a razor-thin line between the two."
"And" - Rain called over his shoulder - "bring the dog! — Nalini Singh

It is important to understand that while oxytocin may be the hub of the evolution of the social brain in mammals, it is part of a very complex system. Part of what it does is act in opposition to stress hormones, and in that sense release of oxytocin feels good - as stress hormones and anxiety do not feel good. — Patricia Churchland

What kind of competition is there in your body? Suppose your brain said ' I'm the most important organ, and the liver said 'I am, and I want to go in a free enterprise-system.' You would rot away in a month, if every organ of your body, were out for itself. — Jacque Fresco

While he attends to his rats, Persinger gives me the lowdown on the haunt theory. Why would a certain type of electromagnetic field make one hear things or sense a presence? What's the mechanism? The answer hinges on the fact that exposure to electromagnetic fields lowers melatonin levels. Melatonin, he explains, is an anti-convulsive; if you have less of it in your system, your brain - in particular, your right temporal lobe - will be more prone to tiny epileptic-esque microseizures and the subtle hallucinations these seizures can cause. — Mary Roach

There has been significant debate in the scientific community about whether desire is a symptom of a system infected with amor deliria nervosa, or a pre-condition of the disease itself.
It is unanimously agreed, however, that love and desire enjoy a symbiotic relationship, meaning that one cannnot exist without the other. Desire is enemy to ncontentment; desire is illness, a feverish brain. Who can be considereed healthy who wants? The very word want suggests a lack, an impoverishment, and that is what desire is: an impoverishment of the brain, a flaw, a mistake. Fortunately, that can now be corrected.
- From The Roots and Repercussions of Amor Deliria Nervosa on Cognitive Functioning, 4th edition, by Dr. Phillip Berryman — Lauren Oliver

What mysteries remain to be revealed in the nervous system, that web of structures both material and ethereal, that network of threads that runs throughout the body, composed of a thousand Ariadne's clues, all leading to the brain, that shadowy central den where the human bones lie scattered and the monsters lurk — Margaret Atwood

I think that cognitive scientists would support the view that our visual system does not directly represent what is out there in the world and that our brain constructs a lot of the imagery that we believe we are seeing. — Galen Rowell

A software system is transparent when you can look at it and immediately see what is going on. It is simple when what is going on is uncomplicated enough for a human brain to reason about all the potential cases without strain — Eric S. Raymond

Reflecting on my experience, I find myself agreeing with the eminent Cambridge philosopher, Dr C. D. Broad, 'that we should do well to consider much more seriously than we have hitherto been inclined to do the type of theory which Bergson put forward in connection with memory and sense perception. The suggestion is that the function of the brain and nervous system and sense organs is in the main eliminative and not productive. Each person is at each moment capable of remembering all that has ever happened to him and of perceiving everything that is happening everywhere in the universe. The function of the brain and nervous system is to protect us from being overwhelmed and confused by this mass of largely useless and irrelevant knowledge, by shutting out most of what we should otherwise perceive or remember at any moment, and leaving only that very small and special selection which is likely to be practically useful.' According — Aldous Huxley

Sadhana It is important not to keep eating through the day. If you are below thirty years of age, three meals every day will fit well into your life. If you are over thirty years of age, it is best to reduce it to two meals per day. Our body and brain work at their best only when the stomach is empty. So be conscious of eating in such a way that within two and a half hours, your food moves out of the stomach, and within twelve to eighteen hours completely out of the system. With this simple awareness you will experience much more energy, agility, and alertness. These are the ingredients of a successful life, irrespective of what you choose to do with it. — Sadhguru

The illusion of the self isn't that there is no such thing as you. Nor does the illusion of free will mean that you cannot make choices. Instead, the illusion is that the self and free will are not really what they seem to be from your, the "end user's," perspective. The illusion of free will is that free will has infinite scope, rather than being a flexible set of feedback loops between higher-order body maps and emotional and memory-storage systems in the brain. The illusion of the self is that self is a kernel, rather than a distributed, emergent system. — Sandra Blakeslee

To make biological survival possible, Mind at Large has to be funnelled through the reducing valve of the brain and nervous system. What comes out at the other end is a measly trickle of the kind of consciousness which will help us to stay alive on the surface of this particular planet. To formulate and express the contents of this reduced awareness, man has invented and endlessly elaborated those symbol-systems and implicit philosophies which we call languages. Every individual is at once the beneficiary and the victim of the linguistic tradition into which he or she has been born
the beneficiary inasmuch as language gives access to he accumulated records of other people's experience, the victim in so far as it confirms him in the belief that reduced awareness is the only awareness and as it be-devils his sense of reality, so that he is all too apt to take his concepts for data, his words for actual things. — Aldous Huxley

In the recumbence of depression, your information-gathering system collates its intelligence and reports to you these facts: (1) there is nothing to do; (2) there is nowhere to go; (3) there is nothing to be; (4) there is no one to know. Without meaning-charged emotions keeping your brain on the straight and narrow, you would lose your balance and fall into an abyss of lucidity. And for a conscious being, lucidity is a cocktail without ingredients, a crystal clear concoction that will leave you hung over with reality. In perfect knowledge there is only perfect nothingness, which is perfectly painful if what you want is meaning in your life. — Thomas Ligotti

Our brain is a circuit board with neurons and terminals ready to be wired. We are born free, then programmed to obey our parents, to tell the truth, pass exams, pursue and achieve, love and propagate, age and fade unfulfilled and uncertain what it has all been for. We swallow the operating system with our mother's milk and sleepwalk into the forest of consumer illusion craving shoes, houses, cars, magazines, experiences that endorse our preconceived dreams and opinions. We grow into our parents. We becomes clones, robots, matchstick men thinking and saying the same, feeling the same, behaving the same, appreciating in books and films and art shows those things we already recognize and understand. — Chloe Thurlow

Really, how much of one's life is made up of these private incidents; how submerged one is. You know, for example, that you will recover from a broken heart, but somehow that piece of information, that factoid, never arrives at the soul or the brain or the nervous system, yes, the nervous system, where it might do some good. But if you know you're going to be all right, why then do you suffer so? To get there. To get where you know you are going to get to anyway. How pathetic, then, to feel about having arrived. I survived, you say. Yes, but what else would you do? No one dies from love. Come, come. — David Gilmour
