Synaptic Quotes & Sayings

Or, if you want to go just a wee bit deeper, we could talk about the nature of freedom itself. Does freedom mean that you are allowed to do whatever you want to do? Or we could talk about all the limiting influences in your life that actively work against your freedom. Your family genetic heritage, your specific DNA, your metabolic uniqueness, the quantum stuff that is going on at a subatomic level where only I am the always-present observer. Or the intrusion of your soul's sickness that inhibits and binds you, or the social influences around you, or the habits that have created synaptic bonds and pathways in your brain. And then there's advertising, propaganda, and paradigms. Inside that confluences of multifaceted inhibitors," she sighed, "what is freedom really? — Wm. Paul Young

In the present chapter, we tried to pinpoint the place in the brain where quantum action might be important to classical behaviour, and have apparently been driven to consider that it is through the cytoskeletal control of synaptic connections that this quantum/classical interface exerts its fundamental influence on the brain's behaviour. — Roger Penrose

Playful stimulation probably hits all kinds of synaptic possibilities. It is all make-believe and all over the map. The potentiality of the synapses and the potentiality of playfulness are a beautiful marriage. — Brian Sutton-Smith

Through the topic of motivation, we begin to see the mental trilogy in action. A mind is not, as cognitive science has traditionally suggested, just a thinking device. It's an integrated system that includes, in the broadest possible terms, synaptic networks devoted to cognitive, emotional, and motivational functions. More important, it involves interactions between networks involved in different aspects of mental life. — Joseph E. Ledoux

Most theoretical work since the proposals of Hebb (1949) and Hayek (1952) has relied upon particular forms of dependent synaptic rules in which either pre- or postsynaptic change is contingent upon closely occurring events in both neurons taking part in the synapse. — Gerald Edelman

Sensitive periods are triggered via the interaction of genetic timing and experience. Sensitive periods are times of rapid learning when thousands of synaptic connections are made each second (Greenough, 1987; ten Cate, 1989). The timing of sensitive periods varies — Louis Cozolino

By the way, pornography? It's a new synaptic pathway. You wake up in the morning, open a thumbnail page, and it leads to a Pandora's box of visuals. There have probably been days when I saw 300 vaginas before I got out of bed. — John Mayer

Does freedom mean that you are allowed to do whatever you want to do? Or we could talk about all the limiting influences in your life that actively work against your freedom. Your family genetic heritage, your specific DNA, your metabolic uniqueness, the quantum stuff that is going on at a subatomic level where only I am the always-present observer. Or the intrusion of your soul's sickness that inhibits and binds you, or the social influences around you, or the habits that have created synaptic bonds and pathways in your brain. And then there's advertising, propaganda, and paradigms. Inside that confluence of multifaceted inhibitors," she said, sighing, "what is freedom really? — Wm. Paul Young

Synaptic summation is the technical term used in neurophysiology for those instances in which some neuron C is fired only by a combination of neurons A and B. — Gregory Bateson

Use-induced cortical reorganization, says Taub, "involves alterations different from mere learning and memory. Rather than producing just increased synaptic strength at certain junctions, which is believed to underlie learning, some unknown mechanism is instead producing wholesale topographic reorganization." And more: we are seeing evidence of the brain's ability to remake itself throughout adult life, not only in response to outside stimuli but even in response to directed mental effort. We are seeing, in short, the brain's potential to correct its own flaws and enhance its own capacities. — Jeffrey M. Schwartz

Complicating matters, adolescent brains are more susceptible to substance abuse and dependence than adult brains, because they're making so many new synaptic connections and sloshing around with so much dopamine. Pretty much all quasi-vices to which human beings turn for relief and escape - drinking, drugs, video games, porn - have longer-lasting and more intense effects in teenagers. It makes acting out especially tempting to them, and it makes their habits especially hard to break. — Jennifer Senior

What is a memory, anyway? Is it an indelible record, unimpeachable, frozen in some synaptic arrangement and stored away for some moment it might be needed in the future? Or is it subject to editing and revision, something plastic that our brains can shape into another form we can handle, something less toxic than the original, something less able to poison us? — Jon Harrison

All of our memories are, like S's, bound together in a web of associations. This is not merely a metaphor, but a reflection of the brain's physical structure. The three-pound mass balanced atop our spines is made up of somewhere in the neighborhood of 100 billion neurons, each of which can make upwards of five to ten thousand synaptic connections with other neurons. A memory, at the most fundamental physiological level, is a pattern of connections between those neurons. Every sensation that we remember, every thought that we think, transforms our brains by altering the connections within that vast network. By the time you get to the end of this sentence, your brain will have physically changed. — Joshua Foer

The complex human eye harvests light. It perceives seven to ten million colors through a synaptic flash: one-tenth of a second from retina to brain. Homo sapiens gangs up to 70 percent of its sense receptors solely for vision, to anticipate danger and recognize reward, but also - more so - for beauty. — Ellen Meloy

The housecleaning our bodies perform while we sleep is powered by the shakti that energizes the sympathetic, parasympathetic, and autonomous nervous systems to send instructions to the lymphatic system, the pituitary gland, and a host of other places in our slumbering forms. Whether it is blood circulating in the veins and arteries, a nerve impulse jumping a synaptic gap in the brain, our body straining while running the hundred-meter dash, or the working out of a physics or organic chemistry problem, our shakti provides the energy to accomplish the activity. — Thomas Ashley-Farrand

Imagine for a moment that we are nothing but the product of billions of years of molecules coming together and ratcheting up through natural selection, that we are composed only of highways of fluids and chemicals sliding along roadways within billions of dancing cells, that trillions of synaptic conversations hum in parallel, that this vast egglike fabric of micron-thin circuitry runs algorithms undreamt of in modern science, and that these neural programs give rise to our decision making, loves, desires, fears, and aspirations. To me, that understanding would be a numinous experience, better than anything ever proposed in anyone's holy text. — David Eagleman

Hebb place the Law of Effect at the synaptic level by proposing a correlation model of synaptic modification similar to that of Hayek (1952). This work was seminal in providing a basis for many subsequent theoretical studies . — Gerald Edelman

The forties are the time when you begin to take notice of certain aches and pains. Your body and brain behave in inexplicable ways: Less hair on your head, more in your ears and nostrils. More memories in the bank, less synaptic firepower with which to access them. Gravity has started to show its inexorable pull. — Hampton Sides

Have you ever looked at a map of our country, Necdet?' Green Headscarf says. 'It's a map of the human mind. We're split by water over two continents, Europe and Anatolia. We are seven per cent Europe, ninety-three per cent Asia. Conscious Thrace, unconscious, pre-conscious, sub-concious Anatolia. And Istanbul - have you ever seen a neuron, Necdet? A brain cell? The marvel is that the synapses don't touch. There is always a gap - there must a gap, otherwise consciousness would not exist. The Bosphorus is that synaptic cleft. Potential can flow across the cleft. It's the cleft that makes consciousness possible. — Ian McDonald

You could double the number of synaptic connections in a very simple neurocircuit as a result of experience and learning. The reason for that was that long-term memory alters the expression of genes in nerve cells, which is the cause of the growth of new synaptic connections. — Eric Kandel

I like the eclipses, the synaptic jumps of short stories. The reader has to participate very actively in the experience. — Deborah Eisenberg

Since the idea that modification of synaptic function can provide a basis for memory arose shortly after the first anatomical description of the synapse a number of models (Hebb 1949 . Hayek 1952 . Kendel 1981) have been proposed in which various cognitive activities are represented by combinations of the firing patterns of individual neurons. — Gerald Edelman

There's that effect that is very physical, very down there at the synaptic level, which really means microscopic cellular level, but also molecular level, because all of those structures are operating on an electrochemical basis and so the changes there are very important. — Antonio Damasio

The pattern recognition theory of mind that I articulate in this book is based on a different fundamental unit: not the neuron itself, but rather an assembly of neurons, which I estimate to number around a hundred. The wiring and synaptic strengths within each unit are relatively stable and determined genetically - that is the organization within each pattern recognition module is determined by genetic design. Learning takes place in the creation of connections between these units, not within them, and probably in the synaptic strengths of the interunit connections. — Ray Kurzweil

During the twentieth century, neuroscientists and psychologists also came to more fully appreciate the astounding complexity of the human brain. Inside our skulls, they discovered, are some 100 billion neurons, which take many different shapes and range in length from a few tenths of a millimeter to a few feet.4 A single neuron typically has many dendrites (though only one axon), and dendrites and axons can have a multitude of branches and synaptic terminals. The average neuron makes about a thousand synaptic connections, and some neurons can make a hundred times that number. — Nicholas Carr

My biggest fear was that the old Charlie was in there somewhere trying to communicate, but a synaptic disconnect made his behavior erratic. — Ruta Sepetys

You were designed to be very smart, Max,' she told me. 'We electrically stimulated your synaptic nerve endings while your brain was developing.' (The director)
And yet I still can't program my DVD player,' I said. (Max) — James Patterson

If I could fall in love with a girl, it'd be her. Those ifs are dangerous. You try them on in your head like dresses, so easy to slide in and out of. If I kissed girls, I'd kiss her. If we kissed, it'd go like this. At some point I dropped the if like a slip and just wore the feeling, nothing between it and my skin. When I kiss her. When it happens. All of it took place in my head, in silence, locked tight in skull bone and the frantic synaptic whispers between neurons, no clues popping out except the passive-aggressive haircut, the incriminating poem.
That's the problem with writers. Too much imagination.
The greater part of me knew it couldn't be real, but the hopeful part, which is more concentrated and condensed, rich in nine essential delusions, thought: It's not all in your head. — Leah Raeder

As the brain matures, one thing that happens is the pruning of the synapses. Synaptic pruning does not occur willy-nilly; it depends largely on how any one brain pathway is used. — Robin Marantz Henig

It seems that the brain has a "small world" architecture - or at least the cortex does. Everything can connect to everything else in a few synaptic steps. — Patricia Churchland

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

The best cure for cranial constipation is emotional fiber. Feel 'something', anything.
Pain, anger, joy; if your heart goes eerily cold or leaps erratically from your chest, your synaptic bowels will soon find release. — Muse

Daydreaming defeats practice; those of us who browse TV while working out will never reach the top ranks. Paying full attention seems to boost the mind's processing speed, strengthen synaptic connections, and expand or create neural networks for what we are practicing. — Daniel Goleman

Nevertheless, they can go screw themselves and they might just have to because I successfully managed to highjack both their boyfriends. Ha! That's the comeback! I can totally feel the inter-synaptic high-fives taking place in my brain. — Addison Moore

This I know: the mind, left to itself, repeats the same stories, the same loops. Mostly ones that don't serve us. So what's practical, what's transformative, is to consciously choose a thought. Then practice it again and again. With emotion, with feeling, with acceptance. Lay down the synaptic pathways until the mind starts playing it automatically. Do this with enough intensity over time and the mind will have no choice. That's how it operates. Where do you think your original loops came from? — Kamal Ravikant

The brain is its own galaxy, with more cells than stars in the Milky Way. The most powerful organ in the body, it rivals any supercomputer, processing 90,000 to 150,000 thoughts a day through billions of neurons and trillions of synaptic connections. Now that we have found a pathway to retrieving memories that before were inaccessible, we are perfecting its function too quickly. — Gwendolyn Womack
