Neuron Quotes & Sayings

He always reminded us that every atom in our bodies was once part of a distant star that had exploded. He talked about how evolution moves from simplicity toward complexity, and how human intelligence is the highest known expression of evolution. I remember him telling me that a frog's brain is much more complex than a star. He saw human consciousness as the first neuron of the universe coming to life and awareness. A spark in the darkness, waiting to spread to fire. — Greg Iles

[...] It is essentially this you can do with a human that you cannot do with a chimpanzee: train them to contribute modestly to society. To become a well-connected neuron in the collective human brain. Without the knowledge and tools of previous generations, humans are largely indistinguishable from chimpanzees. — Magnus Vinding

Some researchers have proposed that experiencing empathy and compassion through the mirror neuron system is equivalent to having compassion for yourself. Thus, "giving is receiving " is a brain-based truth. Insensitivity and selfishness are essentially bad for your brain and your mental health. In contrast, compassion and loving relationships are good for your brain and your mental health. — John B. Arden

In fact, it has been proposed that absolute neuron count, regardless of brain or body size, best predicts a species' mental powers.61 — Frans De Waal

The first attempts to consider the behavior of so-called "random neural nets" in a systematic way have led to a series of problems concerned with relations between the "structure" and the "function" of such nets. The "structure" of a random net is not a clearly defined topological manifold such as could be used to describe a circuit with explicitly given connections. In a random neural net, one does not speak of "this" neuron synapsing on "that" one, but rather in terms of tendencies and probabilities associated with points or regions in the net. — Anatol Rapoport

If my dramatic career doesn't work out, I will go on to research and find cures for Alzheimer's or Parkinson's and other motor neuron diseases. It's a very exciting field of research. But I'd like to continue in drama, so it wouldn't be very smart of me if I blew this amazing opportunity with an inappropriate lifestyle. — Freddie Stroma

The well-being of a neuron depends on its ability to communicate with other neurons. Studies have shown that electrical and chemical stimulation from both a neuron's inputs and its targets support vital cellular processes. Neurons unable to connect effectively with other neurons atrophy. Useless, an abandoned neuron will die. — Lisa Genova

Ceno's brain, soft and pink with blood - and veined with endless whorls and branches of sapphire threaded through every synapse and neuron, inextricable, snarled, intricate, terrible, fragile and new. — Catherynne M Valente

A study published in the October 22, 2014, issue of the journal Neuron suggests that the brain's chemistry changes when we become curious, helping us better learn and retain information. But curiosity is uncomfortable because it involves uncertainty and vulnerability. — Brene Brown

The human brain has 100 billion neurons, each neuron connected to 10 thousand other neurons. Sitting on your shoulders is the most complicated object in the known universe. — Michio Kaku

Crazy' is a term that's used incorrectly and far too often. It's also used with stigma and finality." He tapped his head. "We're all chemicals, Adrian. Our bodies, our brains. It's a simple yet vastly sophisticated system, and every so often, something goes awry. A cell mutation. A neuron misfiring. A lack of a neurotransmitter. — Richelle Mead

Well, technically, they're going to take my brain apart neuron by neuron. But yes, they'll probably just rip yours out.' Under his breath, the Doctor added, 'If they can find it . . . — Trevor Baxendale

Any man could, if he were so inclined, be the sculptor of his own brain. — Santiago Ramon Y Cajal

In my view, while the single neuron is the basic anatomical and information processing-signaling unit of the brain, it is not capable of generating behaviors and, ultimately, thinking. Instead, the true functional unit of the central nervous system is a population of neurons, or neural ensembles or cell assemblies. — Miguel Nicolelis

Most of the complexity of a human neuron is devoted to maintaining its life-support functions, not its information-processing capabilities. Ultimately, we will be able to port our mental processes to a more suitable computational substrate. Then our minds won't have to stay so small. — Ray Kurzweil

There are 100 billion neurons in the adult human brain, and each neuron makes something like 1,000 to 10,000 contacts with other neurons in the brain. Based on this, people have calculated that the number of permutations and combinations of brain activity exceeds the number of elementary particles in the universe. — Vilayanur S. Ramachandran

Stem cell research is the key to developing cures for degenerative conditions like Parkinson's and motor neuron disease from which I and many others suffer. The fact that the cells may come from embryos is not an objection, because the embryos are going to die anyway. — Stephen Hawking

Neurons giveth and neurons taketh away. — Abhijit Naskar

Brain cells are normally not sensitive to light. So by introducing light-sensitive proteins into specific types of neurons, we can now selectively control that specific type of neuron by shining light in the brain. — Feng Zhang

But our brains are different from mice. Their cortex is tiny, which means their ability to learn from experience is tiny. They are built to run on innate rather than learned circuits. Our cortex is huge because we are designed to fill it up with acquired knowledge. We are not meant to run on pre-loaded programs. Every creature in nature runs on as few neurons as possible because neurons are metabolically expensive. They consume more oxygen and glucose than an active muscle. It takes so much energy to keep a neuron alive that they actually make it harder to survive. Neurons only promote survival if you really get your money's worth out of them, by wiring them up with survival-relevant information. Natural selection gave humans a gargantuan number of neurons. That means we were meant to use the experience we've stored in our neurons, not to ignore — Anonymous

The human brain, it has been said, is the most complexly organised structure in the universe and to appreciate this you just have to look at some numbers. The brain is made up of one hundred billion nerve cells or "neurons" which is the basic structural and functional units of the nervous system. Each neuron makes something like a thousand to ten thousand contacts with other neurons and these points of contact are called synapses where exchange of information occurs. And based on this information, someone has calculated that the number of possible permutations and combinations of brain activity, in other words the numbers of brain states, exceeds the number of elementary particles in the known universe. — V.S. Ramachandran

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

What the ordinary person means by a 'miracle' is some gross distortion or suspension of the laws of nature ... but life itself strikes him as commonplace, when in truth a blade of grass or a neuron in the brain is a greater miracle ... — Sydney J. Harris

Our brains contain one hundred billion nerve cells (neurons). Each neuron makes links with ten thousand other neurons to form an incredible three dimensional grid. This grid therefore contains a thousand trillion connections - that's 1,000,000,000,000,000 (a quadrillion). It's hard to imagine this, so let's visualise each connection as a disc that's 1mm thick. Stack up the quadrillion discs on top of each other and they will reach the sun (which is ninety-three million miles from the earth) and back, three times over. — Nessa Carey

It might be thought the height of poor taste to ascribe good fortune to a healthy man with a young family struck down at the age of sixty by an incurable degenerative disorder from which he must shortly die. But there is more than one sort of luck. To fall prey to a motor neuron disease is surely to have offended the Gods at some point, and there is nothing more to be said. But if you must suffer thus, better to have a well-stocked head ... — Tony Judt

One of Sherrington's greatest pupils, Sir John Eccles, held similar views. Eccles won a Nobel Prize for his seminal contributions to our understanding of how nerve cells communicate across synapses, or nerve junctions. In his later years, he worked toward a deeper understanding of the mechanisms mediating the interaction of mind and brain-including the elusive notion of free will. Standard neurobiology tells us that tiny vesicles in the nerve endings contain chemicals called neurotransmitters; in response to an electrical impulse, some of the vesicles release their contents, which cross the synapse and transmit the impulse to the adjoining neuron. In 1986 Eccles proposed that the probability of neurotransmitter release depended on quantum mechanical processes, which can be influenced by the intervention of the mind. This, Eccles said, provided a basis for the action of a free will. — Jeffrey M. Schwartz

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

Some believe that if we could only crack the genetic code and map every neuron in the brain, we will know all of humanity's secrets. After all, if humans have no soul, and if thoughts, emotions and sensations are just biochemical algorithms, why can't biology account for all the vagaries of human societies? — Yuval Noah Harari

She wasn't stupid. She just didn't want to put her neuron power into long sentences. — Margaret Atwood

It was Heraclitus, of course, who came up with the formulation that we are never able to step into the same river twice. ... The obverse of Heraclitus's maxim may be that one is never able to step out of the river the same, twice. A neuron in the brain is altered with every experience. The self, if it exists, must be a constantly evolving thing. Those coming to the banks of the Ganges or Jordan to immerse themselves do not expect to leave the same as they arrive. — James Attlee

There is no scientific theory that could lead us from a detailed map of every single neuron in someone's brain to a conscious experience. We don't even have the beginnings of a theory whose conclusion would be such a system is conscious. — Stuart J. Russell

I'm interested in the ideas that sound a little crazy, such as radical life extension, curing cancer, being able to create a simulation of the human brain and map every neuron. — Bill Maris

A typical neuron makes about ten thousand connections to neighboring neurons. Given the billions of neurons, this means there are as many connections in a single cubic centimeter of brain tissue as there are stars in the Milky Way galaxy. — David Eagleman

Maybe I don't have the most common kind of motor neuron disease, which usually kills in two or three years. — Stephen Hawking

It's not
your fault that your brain is reduced to the size of one neuron and
that it itself is being annihilated by the loneliness. — Danka V.

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

Here is a neuron that fires when I reach and grab something, but it also fires when I watch Joe reaching and grabbing something ... It's as though this neuron is adopting the other person's point of view. — Vilayanur S. Ramachandran

We are compelled to drive toward total knowledge, right down to the levels of the neuron and the gene. When we have progressed enough to explain ourselves in these mechanistic terms ... the result might be hard to accept. — E. O. Wilson

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

Every single decision of your life is predicated on the healthy functioning of the prefrontal cortex. Even a slight malfunction in a tiny chunk of neuron anywhere in the PFC would lead to the mental deficit in your logical decision-making. — Abhijit Naskar

Your brain has a trillion neurons and every neuron has ten thousand little dendrites. The system of inter-communication is awe-inspiring. — Don DeLillo

The doctor who diagnosed me with ALS, or motor neuron disease, told me that it would kill me in two or three years. — Stephen Hawking

Studies of decision-making in the monkey, where activity of single neurons in parietal cortex is recorded, you can see a lot about the time-accuracy trade-off in the monkey's decision, and you can see from the neuron's activity at what point in his accumulation of evidence he makes his decision to make a particular movement. — Patricia Churchland

Neuron is to Consciousness, what D.N.A. is to Life. Thus, Biology of Mind is to the twenty-first century, what Biology of Life was to the twentieth century. — Abhijit Naskar

You probably think Stephen Hawking is in that wheelchair because of a motor neuron disease. But if you got as much barely-legal student poontang as The Hawkster, you'd be in a wheelchair too. — Scott Adams

All evidence indicates that the neuron does not reset. The synapses do not reset. They are always different. They're changing every millisecond. Your brain today is very, very different from what it was when you were 10 years old, and yet you may have profound memories from when you were 10. — Henry Markram

Inspirations sleet through the universe continuously. Their destination, as if they cared, is the right mind in the right place at the right time. They hit the right neuron, there's a chain reaction, and a little while later someone is blinking furiously in the TV lights and wondering how the hell he came up with the idea of pre-sliced bread in the first place.
Leonard of Quirm knew about inspirations. One of his earliest inventions was an earthed metal nightcap, worn in the hope that the damned things would stop leaving their white-hot trails across his tortured imagination. It seldom worked. He knew the shame of waking up to find the sheets covered with nocturnal sketches of seige engines for apple-peeling machines. — Terry Pratchett

Some forms of motor neuron disease are genetically linked, but I have no indication that my kind is. No other member of my family has had it. But I would be in favour of abortion if there was a high risk. — Stephen Hawking

All human behaviour, language, thoughts, feelings, actions, and consciousness emerge from this massively interconnected network of neurons. Each neuron is pretty dumb; it either fires in a certain situation or it doesn't, but out of this mass dumbness comes great cleverness. — Trevor Harley
