Quotes About Brain

There was something built into the human brain by natural selection which was once useful, and which now manifests itself as religion.

The evolution of the capacity to simulate seems to have culminated in subjective consciousness.

The evolution of complex life, indeed its very existence in a universe obeying physical laws, is wonderfully surprising - or would be but for the fact that surprise is an emotion that can exist only in a brain which is the product of that very surprising process

But the very fact that Darwinism is true makes it even more important for us to fight against the naturally selfish and exploitative tendencies of nature.We can do it.Probably no other species of animal or plant can. We can do it because our brains (admittedly given to us by natural selection for reasons pf short-term Darwinian gain) are big enough to see into the future and plot long-term consequences.

Constructing models is something the human brain is very good at. When we are asleep it is called dreaming; when we are awake we call it imagination or, when it is exceptionally vivid, hallucination.

Physics appears to be a complicated subject, because the ideas of physics are difficult for us to understand. Our brains were designed to understand hunting and gathering, mating and child-rearing: a world of medium-sized objects moving in three dimensions at moderate speeds.

my trillions are American, like all my units: one American trillion is a million millions; an American billion is a thousand millions). Our brains are no better equipped to handle extremes of complexity than extremes of size and the other difficult extremes of physics.

Human thoughts and emotions emerge from exceedingly complex interconnections of physical entities within the brain.

what I want to say is that it doesn't matter what particular style of nonsense infects the child brain. Once infected, the child will grow up and infect the next generation with the same nonsense, whatever it happens to be.

They are the outward and visible (audible, etc.) manifestations of the memes within the brain.

They may be perceived by the sense organs of other individuals, and they may so imprint themselves on the brains of the receiving individuals that a copy (not necessarily exact) of the original meme is graven in the receiving brain.

The new copy of the meme is then in a position to broadcast its phenotypic effects, with the result that further copies of itself may be made in yet other brains.

The human brain, and the body that it controls, cannot do more than one or a few things at once. If a meme is to dominate the attention of a human brain, it must do so at the expense of 'rival' memes.

When you plant a fertile meme in my mind you literally parasitize my brain, turning it into a vehicle for the meme's propagation in just the way that a virus may parasitize the genetic mechanism of a host cell.

An 'idea-meme' might be defined as an entity that is capable of being transmitted from one brain to another.

A brain that is good at simulating models in imagination is also, almost inevitably, in danger of self-delusion.

There are more cells in your brain than there are brains in your entire body.

Creierul este o mas? de materie de circa 1300g, pe care o puteÈ›i È›ine în mân? È™i care poate concepe un univers de o sut? de miliarde de ani-lumin? în diametru." Marian C. Diamond

For three million years we were hunter-gatherers, and it was through the evolutionary pressures of that way of life that a brain so adaptable and so creative eventually emerged. Today we stand with the brains of hunter-gatherers in our heads, looking out on a modern world made comfortable for some by the fruits of human inventiveness, and made miserable for others by the scandal of deprivation in the midst of plenty.

Your teen is probably trying—and trying hard—to do everything his or her peers are expected to do as they mature and face increasing responsibilities. But it's a daily struggle when the teen has a deficiency in what are called executive skills, the functions of our brains and thought processes that help us regulate our behavior, set goals and meet them, and balance demands and desires, wants, needs, and have-tos.

To highlight these issues of development in the adolescent brain, a recent article in Parade magazine compared the teenage brain to a Ferrari. It is fast, shiny, sleek, and it handles well. The problem is it has lousy brakes.

Over a period of 10 to 12 years, beginning around puberty, the plasticity of the adolescent brain allows for rewiring. What the final wiring diagram looks like depends on two factors: what teens bring with them up to puberty and what experiences they have over the next 10 years or so.

The fragmented contents of the previous night bubbled in my brain like a carelessly made fish stew. Indigestible chunks appeared on the surface, wobbled in the currents of memory, and sank again.

You can deal with the brain, as I say; it looks sensible, whereas the heart, the human heart, I'm afraid, looks a fucking mess.
