He solved at a stroke the great question of the direction of nerve-currents in their travel through brain and spinal cord.
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.
The stimulus of competition, when applied at an early age to real thought processes, is injurious both to nerve-power and to scientific insight.
The brain seems a thoroughfare for nerve-action passing its way to the motor animal. It has been remarked that Life's aim is an act not a thought. To-day the dictum must be modified to admit that, often, to refrain from an act is no less an act than to commit one, because inhibition is coequally with excitation a nervous activity.
Even when I took the drugs I realized that this just wasn't fun anymore. The drugs had become a part of my routine. Something to wake me up. Something to help me sleep. Something to calm my nerves. There was a time when I was able to wake up, go to sleep, and have fun without a pill or a line to help me function. These days it felt like I might have a nervous breakdown if I didn't have them.
Training can get on a man's nerves. There is no profit or use in denying it.
Oh Christ, the exhaustion of not knowing anything. It's so tiring and hard on the nerves. It really takes it out of you, not knowing anything. You're given comedy and miss all the jokes. Every hour you get weaker. Sometimes, as I sit alone in my flat in London and stare at the window, I think how dismal it is, how heavy, to watch the rain and not know why it falls.
Food is good for the nerves and the spirit. Courage comes from the belly – all else is desperation.
The sound of distant breakers made her heart ache with melancholy. She was in the mood when the sea has a saddening effect upon the nerves. It is only when we are very happy that we can bear to gaze merrily upon the vast and limitless expanse of water, rolling on and on with such persistent, irritating monotony to the accompaniment of our thoughts, whether grave or gay. When they are gay, the waves echo their gaiety; but when they are sad, then every breaker, as it rolls, seems to bring additional sadness and to speak to us of hopelessness and of the pettiness of all our joys.
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.
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.
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.
Every brain is civilized, Every nerve is analyzed, Everything is criticized when you are in need.
You shake my nerves and you rattle my brain.
Pictures, propagated by motion along the fibers of the optic nerves in the brain, are the cause of vision.
If, however, there is to be a war of nerves let us make sure our nerves are strong and are fortified by the deepest convictions of our hearts.
You can always tell when the relationship is over. Little things start getting on your nerves, 'Would you please stop that! That breathing in and out, it's so repetitious.'
Whatever touches the nerves of motive, whatever shifts man's moral position, is mightier than steam, or calorie, or lightening.
Every class of society has its cant of lamentation, which is understood or regarded by none but themselves; and every part of life has its uneasiness, which those who do not feel them will not commiserate. An event which spreads distraction over half the commercial world, assembles the trading companies in councils and committees, and shakes the nerves of a thousand stockjobbers, is read by the landlord and the farmer with frigid indifference.
All living organisms are but leaves on the same tree of life. The various functions of plants and animals and their specialized organs are manifestations of the same living matter. This adapts itself to different jobs and circumstances, but operates on the same basic principles. Muscle contraction is only one of these adaptations. In principle it would not matter whether we studied nerve, kidney or muscle to understand the basic principles of life. In practice, however, it matters a great deal.
My nerves could use a drink.
The cosmos is a vast living body, of which we are still parts. The sun is a great heart whose tremors run through our smallest veins. The moon is a great nerve center from which we quiver forever. Who knows the power that Saturn has over us, or Venus? But it is a vital power, rippling exquisitely through us all the time.
Men wake up aroused in the morning. We can't help it. We just wake up and we want you. And the women are thinking, "How can he want me the way I look in the morning?" It's because we can't see you. We have no blood anywhere near our optic nerve.
The brain is a monstrous, beautiful mess. Its billions of nerve cells - called neurons - lie in a tangled web that displays cognitive powers far exceeding any of the silicon machines we have built to mimic it.
It takes something to get married: nerve, hope, a strong desire to make a certain statement - and it takes something to stay married: more hope, determination, a sense of humor, and needs that are best met by being in a pair.
