Nerve Cells Quotes & Sayings

Clostridium botulinum: Found in jams and preserves that weren't prepared properly, this bad bug produces one of the deadliest toxins on Earth-it enters our nerve cells and paralyzes them. Marketed as Botox, it's injected into people's foreheads to make wrinkles disappear! — Jennifer Gardy

In nerve-free multicellular organisms, the relationships of the cells to each other can only be of a chemical nature. In multicellular organisms with nerve systems, the nerve cells only represent cells like any others, but they have extensions suited to the purpose which they serve, namely the nerves. — Otto Loewi

Touch' is a multi-faceted concept, reflecting the different types of receptors. The simplest are free nerve endings which detect pain and changes in temperature; slightly more complex are Merkel's tactile cells (which detect pressure); followed by Grandry bodies, which consist of two to four tactile cells and detect movement (velocity); and the lamellated Herbst corpuscles (similar to Vater-Pacinian corpuscles in mammals), which are sensitive to acceleration. — Tim Birkhead

Ready made opinions can be distributed day by day through the press, radio, and so on, again and again, till they reach the nerve cell and implant a fixed pattern in the brain. Consequently, guided public opinion is the result, according to Pavlovian theoreticians, of good propaganda technique, and the polls [are] a verification of the temporary successful action of the Pavlovian machinations on the mind. — Joost Meerloo

In Molecules of Emotion, Pert revealed how her study of information-processing receptors on nerve cell membranes led her to discover that the same "neural" receptors were present on most, if not all, of the body's cells. Her elegant experiments established that the "mind" was not focused in the head but was distributed via signal molecules to the whole body. As importantly, her work emphasized that emotions were not only derived through a feedback of the body's environmental information. Through self-consciousness, the mind can use the brain to generate "molecules of emotion" and override the system. While proper use of consciousness can bring health to an ailing body, inappropriate unconscious control of emotions can easily make a healthy body diseased, — Bruce H. Lipton

These are the oldest memories on earth, the time codes carried in every chromosome and gene. Every step we've taken in our evolution is a milestone inscribed with organic memories. From the enzymes controlling the carbon-dioxide cycle, to the organization of the brachial plexus and the nerve pathways of the pyramid cells of the mid-brain. Each is a record of a thousand decisions taken in a chemical crisis. Just as psychoanalysis reconstructs the original traumatic situation in order to release the repressed material, so we are now being plunged back into the archaeopsychic past, uncovering the ancient taboos and drives that have been dormant for epochs. — J.G. Ballard

The magic of the mechanisms inside each genetic structure saying exactly where that nerve cell should go - the complexity of these mathematical models is beyond human comprehension. — Alexander Tsiaras

The moment you are born your death is foretold by your newly minted cells as your mother holds you up, then hands you to your father, who gently tickles the stomach where the cancer will one day form, studies the eyes where melanoma's dark signature is already written along the optic nerve, touches the back where the liver will one day house the cirrhosis, feels the bloodstream that will sweeten itself into diabetes, admires the shape of the head where the brain will fall to the ax-handle of stroke, or listens to your heart, which, exhausted by the fearful ways and humiliations and indecencies of life, will explode in your chest like a light going out in the world. — Pat Conroy

In the words of the late Francis Crick ... You, your joys and your sorrows, your memories and your ambitions, your sense of personal identity and free will, are in fact no more than the behavior of a vast assembly of nerve cells and their associated molecules. (13) — Mary Roach

Depression, in its insidious way, acts as a degenerative disease, harming nerve cells. Like — Peter D. Kramer

Energy is the language spoken by your body. You probably already know that your brain sends bioelectric signals to your organs and muscles through the nerve pathways in your body. But did you ever consider how your brain talks to your cells? — Ilchi Lee

What happens to the brain during exercise? At the start of physical activity, the brain recognizes this period as a moment of stress. And the body's response to stress is to release a certain protein called BDNF or Brain-Derived Neurotrophic Factor. This protein gives some sort of protective and reparative component to the memory and nerve cells. — Osnat Duman

Ladies and gentlemen, today we're here to honor electricity, the charge that charges everything from those electrons snapping in our brain to our father the sun. What's the sun It's kind of like a brain. Electromagnetic field, solar flares sparking back and forth from those nerve cells. We're all one, folks, giant blobs of electricity, all of us. Positive & negative, electromagnetic fields just circling each other. Positive, negative, north, south, male and female. Looking for that electric moment. Magnet to magnet, opposites attract. — Robin Green

The relative importance of the white and gray matter is often misunderstood. Were it not for the manifold connection of the nerve cells in the cortex by the tens of millions of fibres which make up the under-estimated white matter, such a brain would be useless as a telephone or telegraph station with all the interconnecting wires destroyed. — Edward Anthony Spitzka

Nerve cells communicate with one another at specialized points called synapses. And these synapses are plastic - they can be modified by learning. — Eric Kandel

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

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

Odd to think that the piece of you I know best is already dead. The cells on the surface of your skin are thin and flat without the blood vessels or nerve endings. Dead cells, thickest on the palms of your hands and the soles of your feet. — Jeanette Winterson

The human brain is estimated to have about a hundred billion nerve cells, two million miles of axons, and a million billion synapses, making it the most complex structure, natural or artificial, on earth. — Tim Green

Made up of a dozen billion microscopic nerve-cell units interconnected by millions upon millions of conducting nerve-threads weaving incredibly intricate patterns, the brain, as an object of research, presents a defiant challenge to its own ingenuity. — William Feindel

The actual organization of behavior goes on the level of the individual nerve cells and their connections, and we have a hundred billion nerve cells, probably a hundred trillion connections. It's just mind-boggling to think of all the different ways in which they're arranged in a baby's head. — Steven Pinker

The hunger drive is truly a mind-body connection. Eating is so important that the nerve cells of appetite are located in the hypothalamus region of the brain. — Evelyn Tribole

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

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

Just tell us," Harding said, bent over the wound. "Darwin had no idea ... " "That life is so unbelievably complex," Malcolm said. "Nobody realizes it. I mean, a single fertilized egg has a hundred thousand genes, which act in a coordinated way, switching on and off at specific times, to transform that single cell into a complete living creature. That one cell starts to divide, but the subsequent cells are different. They specialize. Some are nerve. Some are gut. Some are limb. Each set of cells begins to follow its own program, developing, interacting. Eventually there are two hundred and fifty different kinds of cells, all developing together, at exactly the right time. Just when the organism needs a circulatory system, the heart starts pumping. Just when hormones are needed, the adrenals start to make them. Week after week, this unimaginably complex development proceeds perfectly - perfectly. It's incredible. No human activity comes close. — Michael Crichton

There is some evidence that chronic severe depression causes some atrophy or shrinkage in the hippocampus. Depressive illness could therefore be seen as a very subtle form of degeneration in some nerve cells. — Stefan Cembrowicz

The human brain is the last, and greatest, scientific frontier. It is truly an internal cosmos that lies contained within our skulls. The more than 100 billion nerve cells and trillion supporting cells that make up your brain and mine constitute the most elaborate structure in the known universe. — Joel Davis

By mobilizing our thoughts and practicing new ways of thinking, we can reshape our nerve cells and change the way our brains work. — Dalai Lama XIV

Among the millions of nerve cells that clothe parts of the brain there runs a thread. It is the thread of time, the thread that has run through each succeeding wakeful hour of the individual. — Wilder Penfield

The body and dendrites of a nerve cell are specialized for the reception and integration of information which is conveyed as impulses that are fired from other nerve cells along their axons. — John Eccles

There is one thing that humans strive for with every cell, every gene, every nerve fiber of our beings ... More than Mallomars, more than hot sex, we want to belong. — Cynthia Heimel

Three quick breaths triggered the responses: he fell into the floating awareness ... focusing the consciousness ... aortal dilation ... avoiding the unfocused mechanism of consciousness ... to be conscious by choice ... blood enriched and swift-flooding the overload regions ... one does not obtain food-safety freedom by instinct alone ... animal consciousness does not extend beyond the given moment nor into the idea that its victims may become extinct ... the animal destroys and does not produce ... animal pleasures remain close to sensation levels and avoid the perceptual ... the human requires a background grid through which to see his universe ... focused consciousness by choice, this forms your grid ... bodily integrity follows nerve-blood flow according to the deepest awareness of cell needs ... all things/cells/beings are impermanent ... strive for flow-permanence within ... — Frank Herbert

An immune system of enormous complexity is present in all vertebrate animals. When we place a population of lymphocytes from such an animal in appropriate tissue culture fluid, and when we add an antigen, the lymphocytes will produce specific antibody molecules, in the absense of any nerve cells. I find it astonishing that the immune system embodies a degree of complexity which suggests some more or less superficial though striking analogies with human language, and that this cognitive system has evolved and functions without assistance of the brain. — Niels Kaj Jerne

We are in the mountains and they are in us, kindling enthusiasm, making every nerve quiver, filling every pore and cell of us ... How glorious a conversion, so complete and wholesome it is, scarce memory enough of old bondage days left as a standpoint to view it from! In this newness of life we seem to have been so always — John Muir

The advances of biology during the past 20 years have been breathtaking, particularly in cracking the mystery of heredity. Nevertheless, the greatest and most difficult problems still lie ahead. The discoveries of the 1970's about the chemical roots of memory in nerve cells or the basis of learning, about the complex behavior of man and animals, the nature of growth, development, disease and aging will be at least as fundamental and spectacular as those of the recent past. — H. Bentley Glass

The structure of the human brain is enormously complex. It contains about 10 billion nerve cells (neurons), which are interlinked in a vast network through 1,000 billion junctions (synapses). The whole brain can be divided into subsections, or sub-networks, which communicate with each other in a network fashion. All this results in intricate patterns of intertwined webs, networks of nesting within larger networks. — Fritjof Capra

A person's mental activities are entirely due to the behavior of nerve cells, glial cells, and the atoms, ions, and molecules that make them up and influence them. — Francis Crick

The injurious agent in cigarettes comes principally from the burning paper wrapper. The substance thereby formed is called "acrolein." It has a violent action on the nerve centers, producing degeneration of the cells of the brain, which is quite rapid among boys. Unlike most narcotics, this degeneration is permanent and uncontrollable. I employ no person who smokes cigarettes. — Thomas A. Edison

With its hundred billion nerve cells, with their hundred trillion interconnections, the human brain is the most complex phenomenon in the known universe - always, of course, excepting the interaction of some six billion such brains and their owners within the socio-technological culture of our planetary ecosystem! — Steven Rose

Corporeal reality is much more rich and precious than we realize. It feels good to have a body, to surge on currents of emotion, to have nerve endings, mitochondria in our cells, tangible focused energy, the embodiment of light - given a voice. — Laurie Perez

Take care with manufactured chemicals, certainly. Your safety and long term health are more important than anything. Yet don't forget that if you grow even a dozen different plants, you are surrounded by chemistry. Inside their cells even the most ordinary plants creates potent fungicides, insecticides, irritants, balms, hallucinogens, sedatives, nerve toxins, cell repair stimulants, lures, repellents ... you name it. Treat all plants with respect! — Janet Macunovich

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

The mind is the seat of perception of the things we see, hear, and feel. It is through the mind that we see the beauties of the earth and sky, or music, of art, in fact, of everything. That silent shuttle of thought working in and out through cell and nerve weaves into one harmonious whole the myriad moods of mind, and we call it life. — Charles Fillmore
