Brain Structure Quotes

The human brain, then, is the most complicated organization of matter that we know.

Now, we used to think the brain was like a computer. But now, we realize that's not true. There's no programming of the brain. There's no Windows. And we think the brain is more like a large corporation. Because think of the unconscious mind. In a corporation, you have subdivisions which operate independently of the main office.

The brain of man, like that of all animals is double, being parted down its centre by a thin membrane. For this reason pain is not always felt in the same part of the head, but sometimes on one side, sometimes on the other, and occasionally all over.

Brains, you see, vary a lot from person to person - they vary as much as faces do.

The brain was designed by evolution, so each part of it is optimized for what it does, and it's incredibly, incredibly complex.

Some scholars argue that although the brain might contain neural subsystems, or modules, specialized for tasks like recognizing faces and understanding language, it also contains a part that constitutes a person, a self: the chief executive of all the subsystems.

Your brain does not manufacture thoughts. Your thoughts shape neural networks.

Shaped a little like a loaf of French country bread, our brain is a crowded chemistry lab, bustling with nonstop neural conversations.Imagine the brain, that shiny mound of being, that mouse-gray parliament of cells, that dream factory, that petit tyrant inside a ball of bone, that huddle of neurons calling all the plays, that little everywhere, that fickle pleasuredome, that wrinkled wardrobe of selves stuffed into the skull like too many clothes into a gym bag.

Much more of the brain is devoted to movement than to language. Language is only a little thing sitting on top of this huge ocean of movement.

The amygdala is one of those brain structures that a lot of people know a little bit about, and there's a definite tendency to conflate the amygdala and the fear response itself - as if the amygdala, and the amygdala alone, 'causes' fear.

The brain isn't like the heart. They learned how to transplant a heart. The brain is more complex.

Then one day, we’ll put the reward in the old place, and put in the rat, and, by golloy, the old habit will rememerge right away. habits never really disappear. They’re encoded into the sturctures of our brain, and that’s a huge advantage for us, because it would be awful if we had to relearn how to drive after every vacation. The problem is that your brain can’t tell the difference between bad and good habits, and so if you have a bad one, it’s always lurking there, waiting for the right cues and rewards.

Those who grew up digital have different brains.

When it comes to brains, size matters. It's not all that matters, of course. Whales and dolphins have brains that are larger than humans', but few of the flippered and fluked set win tenure at Stanford. Our brains are the largest in proportion to body size, and they're also highly sophisticated.

And in man is a three-pound brain which, as far as we know, is the most complex and orderly arrangement of matter in the universe.

As someone who was basically a software engineer for many years, I became fascinated with how the brain functions and is put together and works in such a different fashion than computers do.

As long as our brain is a mystery, the universe, the reflection of the structure of the brain will also be a mystery.

You certainly can't tell anything from the microscopic structure of the brain whether the person was an idiot or a genius.

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.

The brain weighs only three pounds, yet it is the most complex object in the solar system.

The brain, is the most complex thing we have yet discovered in our universe.

I consider the differences between man and animals in propensities, feelings, and intellectual faculties, to be the result of the same cause as that which we assign for the variations in other functions, viz. difference of organization; and that the superiority of man in rational endowments is not greater than the more exquisite, complicated, and perfectly developed structure of his brain, and particularly of his ample cerebral hemispheres, to which the rest of the animal kingdom offers no parallel, nor even any near approximation, is sufficient to account for.

Neuroscientists talk a lot about brain circuits. In fact, the word 'circuit' is probably misleading. We do not know where most circuits begin and end. And unlike an electrical circuit, brain connections are heavily reciprocal and recursive, so that a direction of information flow can be inferred but sometimes not proven.

The brain is really hard to see. The whole thing is very large - the human brain is several pounds in weight - but the connections between brain cells, known as synapses, are really tiny. They're nanoscale in dimension. So if you want to see how the cells of the brain are connected in networks, you have to see those connections, those synapses.

Communications technology changes possibilities for communication, but that doesn't mean it changes the inherited structure of the brain. So you may think that you're addicted to online reading, but as soon as it isn't available anymore, your brain will pretty immediately adjust to other forms of reading. It's a habit like all habits.
