Brain By Scientists Quotes & Sayings

When scientists get old, they get interested in the brain, and I'm a little bit afraid I'm falling into that. — Elizabeth Blackburn

The discovery that modified speech can drive neuroplasticity in the mature brain is just the most dramatic example (so far) of how sensory stimuli can rewire neuronal circuits. In fact, soon after Merzenich and Tallal published their results, other scientists began collecting data showing that, as in my own studies of OCD patients, brain changes do not require changes in either the quantity or the quality of sensory input. To the contrary: the brain could change even if all patients did was use mindfulness to respond to their thoughts differently. Applied mindfulness could change neuronal circuitry. — Jeffrey M. Schwartz

The tape measures and weighing scales of the Victorian brain scientists have been supplanted by powerful neuroimaging technologies, but there is still a lesson to be learned from historical examples such as these. State-of-the-art brain scanners offer us unprecedented information about the structure and working of the brain. But don't forget that, once, wrapping a tape measure around the head was considered modern and sophisticated, and it's important not to fall into the same old traps. As we'll see in later chapters, although certain popular commentators make it seem effortlessly easy, the sheer complexity of the brain makes interpreting and understanding the meaning of any sex differences we find in the brain a very difficult task. But the first, and perhaps surprising, issue in sex differences research is that of knowing which differences are real and which, like the intially promising cephalic index, are flukes or spurious. — Cordelia Fine

Mankind will someday realize that we are actually in contact with the dead and with the other world, whatever it is; right now we could predict, if we only exerted enough mental will, what is going to happen within the next hundred years and be able to take steps to avoid all kinds of catastrophes. When a man dies he undergoes a mutation in his brain that we know nothing about now but which will be very clear someday if scientists get on the ball. The bastards right now are only interested in seeing if they can blow up the world. — Jack Kerouac

We underestimate the power of science, and overestimate the power of personal observation. A peer-reviewed, journal-published, replicated report is worth far more than what you see with your own eyes. Our own eyes can deceive us. People can fool themselves, hallucinate, and even go insane. The controls on publication in major journals are more trustworthy than the very fabric of your brain. If you see with your own eyes that the sky is blue, and Science says it is green, then sir, I advise that you trust in Science.
This is not what most scientists will tell you, of course; but I think it is pragmatically true. Because in real life, what happens is that your eyes have a little malfunction and decide that the sky is green, and science will tell you that the sky is blue. — Eliezer Yudkowsky

Many scientists (the most notable being Albert Einstein) think in visual, spatial, and physical images rather than in mathematical terms and words. (N.B.: That the theoretical physicist, Stephen Hawking, used an arboreal term to picture the cosmos [i.e., affirming that the universe "could have different branches,"] is a tribute to his [very visual] primate brain.) — David B. Givens

AI scientists tried to program computers to act like humans without first answering what intelligence is and what it means to understand. They left out the most important part of building intelligent machines, the intelligence! "Real intelligence" makes the point that before we attempt to build intelligent machines, we have to first understand how the brain thinks, and there is nothing artificial about that. Only then can we ask how we can build intelligent machines — Jeff Hawkins

It is easy to make out three areas where scientists will be concentrating their efforts in the coming decades. One is in physics, where leading theorists are striving, with the help of experimentalists, to devise a single mathematical theory that embraces all the basic phenomena of matter and energy. The other two are in biology. Biologists-and the rest of us too-would like to know how the brain works and how a single cell, the fertilized egg cell, develops into an entire organism — Dennis Flanagan

A ... reason we are so-so scientists is that our brains were shaped for fitness, not for truth. Sometimes truth is adaptive, but sometimes it is not. — Steven Pinker

My staff is made up of politicians, Rachel, not scientists. You've met Dr. Marlinson. I think he's terrific, but if I let an astrophysicist loose on my team of left-brain, think-inside-the-box intellectuals, I'll end up with a herd of deer in the headlights. — Dan Brown

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

Our lives are shaped as profoundly by personality as by gender or race. And the single most important aspect of personality - the "north and south of temperament," as one scientist puts it - is where we fall on the introvert-extrovert spectrum. Our place on this continuum influences our choice of friends and mates, and how we make conversation, resolve differences, and show love. It affects the careers we choose and whether or not we succeed at them. It governs how likely we are to exercise, commit adultery, function well without sleep, learn from our mistakes, place big bets in the stock market, delay gratification, be a good leader, and ask "what if."* It's reflected in our brain pathways, neurotransmitters, and remote corners of our nervous systems. Today introversion and extroversion are two of the most exhaustively researched subjects in personality psychology, arousing the curiosity of hundreds of scientists. — Susan Cain

Scientists who study brain-wave activity found that the longer one watches television, the more likely the brain will slip into "alpha" level: a slow, steady brain-wave pattern in which the mind is in its most receptive mode. It is noncoggnitive mode; i.e., information can be placed into the mind directly, without viewer participation. — Jerry Mander

Habits, scientists say, emerge because the brain is constantly looking for ways to save effort. — Charles Duhigg

The brain scans and mood swings of an infatuated lover, scientists have recently discovered, look remarkably similar to the brain scans and mood swings of a cocaine addict - and not surprisingly, as it turns out, because infatuation is an addiction, with measurable chemical effects on the brain. As the anthropologist and infatuation expert Dr. Helen Fisher has explained, infatuated lovers, just like any junkie, will go to unhealthy, humiliating, and even physically dangerous lengths to procure their narcotic. — Elizabeth Gilbert

The mind of the polyglot is a very particular thing, and scientists are only beginning to look closely at how acquiring a second language influences learning, behavior and the very structure of the brain itself. — Jeffrey Kluger

When an animal is looking for something that increases its chances of survival and reproduction (e.g. food, partners or social status), the brain produces sensations of alertness and excitement, which drive the animal to make even greater efforts because they are so very agreeable. In a famous experiment scientists connected electrodes to the brains of several rats, enabling the animals to create sensations of excitement simply by pressing a pedal. When the rats were given a choice between tasty food and pressing the pedal, they preferred the pedal (much like kids preferring to play video games rather than come down to dinner). The rats pressed the pedal again and again, until they collapsed from hunger and exhaustion — Yuval Noah Harari

So often, we look at lacking as a negative thing, but do you know God is looking for people who lack? He seeks out those who are missing something. He does this because the more you lack, the more He can increase. The more you miss, the more He can fill in. God is not necessarily looking for rocket scientists and brain surgeons to start businesses. You do not need your master's degree or a million dollars to start a business. What God is looking for are willing saints to yield their destinies. — V.L. Thompson

People have a basic desire to feel good about themselves, and we therefore have a tendency to be unconsciously biased in favor of traits similiar to our won, even such seemingly meaningless traits as our names. Scientists have even identified a discrete area of the brain, called the dorsal striatum, as the structure that mediates much of this bias. — Leonard Mlodinow

As a number of scientists have
noted, research on the human brain is complicated by the fact
that the brain is struggling to understand itself. This three-pound
organ is perhaps the only bit of matter in the universe - at least as
far as we know - that is observing itself, wondering about itself,
trying to analyze itself, and attempting to gain better control of
its own capabilities. — Betty Edwards

A single human brain has about a hundred million nerve cells ... and a computer program that throws light on the mind/brain problem will have to incorporate the deepest insights of biologists, nerve scientists, psychologists, physiologists, linguists, social scientists, and even philosophers. — Tony Hoare

As I spoke with scientists about the way fat behaves, I couldn't resist drawing an analogy to the realm of narcotics. If sugar is the methamphetamine of processed food ingredients, with its high-speed, blunt assault on our brains, then fat is the opiate, a smooth operator whose effects are less obvious but no less powerful. — Michael Moss

Until recently, scientists were largely convinced that anger, fear, sadness, happiness, and disgust, as emotional faculties, arise from separate, innate, culturally universal neural modules in the brain (for a review see [5,9]). — Anonymous

The brain scientists are the wave of the future in the financial world. If you seek to maximize understanding, whether you're in academia or in the investment community, you'd better pay serious attention to them. — Daniel Kahneman

According to the 'Language Institute Regina Coeli' 'Learning a language allows parts of your brain to grow' By using MRI technology, scientists have collected evidence to prove that parts of the brain actually grow when a person studies a language intensively over a longer period of time. 'Multilingualism keeps Alzheimer's at bay — Hanife Hassan O'Keeffe

Biology doesn't know in advance what the end product will be; there's no Stuffit Compressor to convert a human being into a genome. But the genome itself is very much akin to a compression scheme, a terrifically efficient description of how to build something of great complexity-perhaps more efficient than anything yet developed in the labs of computer scientists (never mind the complexities of the brain, there are trillions of cells in the rest of the body, and they are all supervised by the same 30,000-gene genome). And although there is no counterpart in nature to a program that compresses a picture into a compact description, there is a natural counterpart to the program that decompresses the compressed encoding, and that's the cell. Genome in, organism out. Through the logic of gene expression, cells are self-regulating factories that translate genomes into biological structure. — Gary F. Marcus

Some say that eating chocolate is better than kissing, and scientists have dutifully tested this hypothesis by carrying out a set of experiments. In 2007, a team led by Dr. David Lewis recruited pairs of passionate lovers, whose brain activity and heart rate were monitored first while they kissed each other and then while they ate chocolate (separately). The researchers found that although kissing set the heart pounding, the effect did not last as long as when the participants ate chocolate. The study also showed that when the chocolate started melting, all regions of the brain received a boost far more intense and longer lasting than the brain activity measured while kissing. — Mark Miodownik

Indeed, brain scans done by scientists at Washington University in St. Louis indicate that areas used to recall memories are the same as those involved in simulating the future. In particular, the link between the dorsolateral prefrontal cortex and the hippocampus lights up when a person is engaged in planning for the future and remembering the past. — Michio Kaku

Geometric shapes hold an energy pattern, and scientists did some experiments which say certain geometric shapes can affect matter around them. It's simply because when a human looks at a shape, they instantly receive energy from their brain. — Tom DeLonge

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

Scientists now know that the brain is incapable of paying attention to two things at the same time. — Susan Cain

Anyone who can read history with both hemispheres of the brain knows that a world comes to an end every instant
the waves of time leave washed up behind themselves only dry memories of a closed & petrified past
imperfect memory, itself already dying & autumnal. And every instant also gives birth to a world
despite the cavillings of philosophers & scientists whose bodies have grown numb
a present in which all impossibilities are renewed, where regret & premonition fade to nothing in one presential hologrammatical psychomantric gesture. — Hakim Bey

The world needs scientists, engineers - and if a brain is qualified to do such work, it should be encouraged, not smothered because it is a female brain. — Marguerite Rawalt

Scientists are cautiously beginning to question the view that the brain is the sole and absolute ruler over the body. The gut not only possesses an unimaginable number of nerves, those nerves are also unimaginably different from those of the rest of the body. The gut commands an entire fleet of signaling substances, nerve-insulation materials, and ways of connecting. There is only one other organ in the body that can compete with the gut for diversity - the brain. The gut's network of nerves is called the "gut brain" because it is just as large and chemically complex as the gray matter in our heads. Were the gut solely responsible for transporting food and producing the occasional burp, such a sophisticated nervous system would be an odd waste of energy. Nobody would create such a neural network just to enable us to break wind. There must be more to it than that. — Giulia Enders

Even this abbreviated rundown of mind-brain philosophies would not be complete without what the Australian philosopher David Chalmers calls "don't-have-clue materialism." This is the default position of those who have no idea about the origins of consciousness or the mind but assert that "it must be physical, as materialism must be true," as Chalmers puts it. "Such a view is held widely, but rarely in print." One might add that many working scientists hold this view without really reflecting on the implications of it. — Jeffrey M. Schwartz

Scientists say we use 10% of our brain. That's way too much. By doing just a little every day, I can gradually let the task completely overwhelm me. — Ashleigh Brilliant

Lisa, love is magical," Rema said. "Scientists give such simplified explanations for it, and they're wrong, because love isn't something that happens in your brain. Love happens in your soul. — Monique Snyman

I realized, 'Oh my gosh! I'm having a stroke! I'm having a stroke!' The next thing my brain says to me is, 'Wow! This is so cool! How many brain scientists have the opportunity to study their own brain from the inside out?' — Jill Bolte Taylor

Using MRI scans, scientists can now read thoughts circulating in our brains. Scientists can also insert a chip into the brain of a patient who is totally paralyzed and connect it to a computer, so that through thought alone that patient can surf the web, read and write e-mails, play video games, control their wheelchair, operate household appliances, and manipulate mechanical arms. In fact, such patients can do anything a normal person can do via a computer. — Michio Kaku

Both scientists and laypeople can find themselves seduced into the easy trap of wanting to assign each function of the brain to a specific location. Perhaps because of pressure for simple sound bites, a steady stream of reports in the media (and even in the scientific literature) has created the false impression that the brain area for such-and-such has just been discovered. Such reports feed popular expectation and hope for easy labeling, but the true situation is much more interesting: the continuous networks of neural circuitry accomplish their functions using multiple, independently discovered strategies. The brain lends itself well to the complexity of the world, but poorly to clear-cut cartography. — David Eagleman

Scientists have discovered that the small brave act of cooperating with another person, of choosing trust over cynicism, generosity over selfishness, makes the brain light up with quiet joy. — Natalie Angier

Neuroscience may one day resolve how planning takes place. The first hints are coming from the hippocampus, which has long been known to be vital both for memory and for future orientation. The devastating effects of Alzheimer's typically begin with degeneration of this part of the brain. As with all major brain areas, however, the human hippocampus is far from unique. Rats have a similar structure, which has been intensely studied. After a maze task, these rodents keep replaying their experiences in this brain region, either during sleep or sitting still while awake. Using brain waves to detect what kind of maze paths the rats are rehearsing in their heads, scientists found that more is going on than a consolidation of past experiences. — Frans De Waal

It is now established by verifiable evidence that religion stultifies the brain and is the great obstacle in the path of intellectual progress.
The more religious a person is, the more he is steeped in ignorance and superstition, the less is his sense of moral responsibility. The more intelligent a person, the less religious he is. There is an old saying that 'where there are three scientists, there are two atheists.'
The countries whose governments are dominated by religion and religious institutions are the most backward. By the same token, the countries whose people are the most enlightened, and whose governments are based upon the principle of secularism - the separation of church and state - are the most progressive.
And let me tell you: When man is intellectually free, the progress he will make is beyond calculation. — Joseph Lewis

Scientists still know very little about how the olfactory cortex in the brain converts impulses from receptors into conscious senses of smell. But Harry wasn't thinking so much about the hows, he just knew that when he smelled her, all sorts of things started happening in his head and body. Like his eyelids closing halfway, like his mouth spreading into a broad grin and his mood soaring. — Jo Nesbo

I want to know where joy lives. I'd interview scientists, religious leaders and heads of state. I'd want to find out exactly what makes people happy. I'd want to look into the biology, the chemistry of the human brain. — Goldie Hawn

He found that mice with a defect in their CREB activator gene were virtually incapable of forming long-term memories. They were amnesiac mice. But even these forgetful mice could learn a bit if they had short lessons with rest in between. Scientists theorize that we have a fixed amount of CREB activator in the brain that can limit the amount we can learn in any specific time. If we try to cram before a test, it means that we quickly exhaust the amount of CREB activators, and hence we cannot learn any more - at least until we take a break to replenish the CREB activators. — Michio Kaku

Every brilliant experiment, like every great work of art, starts with an act of imagination. Unfortunately, our current culture subscribes to a very narrow definition of truth. If something can't be quantified and calculated, then it can't be true. Because this strict scientific approach has explained so much, we assume that it can explain everything. But every method, even the experimental method, has limits. Take the human mind. Scientists describe our brain in terms of its physical details; they say we are nothing but a loom of electrical cells and synaptic spaces. What science forgets is that this isn't how we experience the world. (We feel like the ghost, not like the machine.) It is ironic but true: the one reality science cannot reduce is the only reality we will ever know. This is why we need art. By expressing our actual experience, the artist reminds us that our science is incomplete, that no map of matter will ever explain the immateriality of our consciousness. — Jonah Lehrer

I have been diagnosed with Amyotrophic Lateral Sclerosis (ALS). It's a terminal disease with an average lifespan of two to five years post-diagnosis, and scientists don't know what causes it. ALS prevents your brain from talking to your muscles. As a result, muscles die. As a result, every 90 minutes people die. I am a person. — Steve Gleason

It uses the greatest random-access indexing system ever invented - one that computer scientists haven't come even close to replicating. Whereas an index in the back of a book provides a single address - a page number - for each important subject, each subject in the brain has hundreds if not thousands of addresses. Our internal memories are associational, nonlinear. You don't need to know where a particular memory is stored in order to find it. It simply turns up - or doesn't - when you need it. Because of the dense network that interconnects our memories, we can skip around from memory to memory and idea to idea very rapidly. — Joshua Foer

Scientists have a second brain where other people have their hearts. — Martha Albrand

Some social scientists say that in-group/out-group biases are hard-wired into the human brain. Even without overt prejudice, it is cognitively convenient for people to sort items into categories and respond based on what is usually associated with those categories: a form of statistical discrimination, playing the odds. — Rosabeth Moss Kanter

Scientists have made extraordinary advances in understanding the brain and its disorders. — Kay Redfield Jamison
