Quotes About Brain

I just don't know what I'd do without a brain, Simone!" I say. "I mean, what's a person without one?

Smell and taste are processed in parts of our brains that are reactive and emotional rather than intellectual, which is one reason developing a good vocabulary of aromas is so difficult. It's a long journey from our lizard brain way up to where language is processed.

The reason we remember song lyrics more easily than poetry is that music is stored in the cleaner, mathematical side of our brains. Poetry is shoveled into the cluttered, creative side.

Based on my reading, the human brain is mostly a voracious consumer of patterns, a soft pudgy gray Pac-Man of concepts. Games are just exceptionally tasty patterns to eat up.

They have more in common with how our brain visualizes things than they do with how reality is actually formed. Since our perception of reality is basically abstraction anyway,*

Fun is all about our brains feeling good — the release of endorphins* into our system. There are a variety of complex cocktails of chemicals that result in different sensations. Science has shown that the pleasurable chills that we get down the spine after exceptionally powerful music or a really great book are caused by the same sorts of chemicals we get when we have cocaine, an orgasm, or chocolate.

Stress imbalances microbiome, disrupts gut, promotes brain dysfunction Imbalanced microbiome disrupts gut, promotes brain dysfunction, induces exaggerated response to stress Dysfunctional gut imbalances microbiome, promotes brain dysfunction, induces exaggerated response to stress

The brain is a three-pound mass you can hold in your hand that can conceive of a universe a hundred billion light years across. —Marian Diamond

The lesson of these new insights is that our brain is entirely like any of our physical muscles: Use it or lose it.

If we were magically shrunk and put into someone's brain while she was thinking, we would see all the pumps, pistons, gears and levers working away, and we would be able to describe their workings completely, in mechanical terms, thereby completely describing the thought processes of the brain. But that description would nowhere contain any mention of thought! It would contain nothing but descriptions of pumps, pistons, levers! —G. W. LEIBNIZ (1646–1716)

Phosphatidylserine is a natural constituent of the cell membrane but is found in especially high concentrations in the brain. Supplementing with phosphatidylserine slows down memory loss and has been shown to reverse memory loss in some patients with age-related memory decline. It also lowers levels of cortisol, a principal hormone of aging.

In the latest brain image studies, we can see real-time movies of individual interneuronal connections actually creating new synapses (connection points between neurons), so we can see our brain create our thoughts and in turn see our thoughts create our brain.

Predicting the future is actually the primary reason that we have a brain.

our primate ancestors was the development of a larger cerebral cortex as well as the development of increased volume of gray-matter tissue in certain regions of the brain.32 This change occurred, however, on the very slow timescale of biological evolution and still involves an inherent

it could be simply an accident of fate that our brains are too weak to understand themselves. Think of the lowly giraffe, for instance, whose brain is obviously far below the level required for self-understanding—yet it is remarkably similar to our brain.

However, we have the benefits of the billions of years of evolution that have already taken place, which are responsible for the greatly increased order of complexity in the natural world. We can now benefit from it by using our evolved tools to reverse engineer the products of biological evolution (most importantly, the human brain).

Hoewel we de illusie hebben dat we beelden met hoge resolutie ontvangen van onze ogen, stuurt de oogzenuw slechts contouren en aanwijzingen over interessante punten in ons blikveld naar het brein. We 'hallucineren' eigenlijk de wereld vanuit ons corticale geheugen.

Once nonbiological intelligence gets a foothold in the human brain (this has already started with computerized neural implants), the machine intelligence in our brains will grow exponentially (as it has been doing all along), at least doubling in power each year.

A universe saturated with intelligence at 1090 cps would be one trillion trillion trillion trillion trillion times more powerful than all biological human brains on Earth today.3 Even a one-kilogram "cold" computer has a peak potential of 1042 cps, as I reviewed in chapter 3, which is ten thousand trillion (1016) times more powerful than all biological human brains.

Our ability to create models—virtual realities—in our brains, combined with our modest-looking thumbs, has been sufficient to usher in another form of evolution: technology. That development enabled the persistence of the accelerating pace that started with biological evolution. It will continue until the entire universe is at our fingertips.

we are constantly predicting the future and hypothesizing what we will experience. This expectation influences what we actually perceive. Predicting the future is actually the primary reason that we have a brain.

Moreover, the detailed arrangement of connections and synapses in a given region is a direct product of how extensively that region is used. As brain scanning has attained sufficiently high resolution to detect dendritic-spine growth and the formation of new synapses, we can see our brain grow and adapt to literally follow our thoughts. This gives new shades of meaning to Descartes' dictum "I think therefore I am.

We have fifty billion neurons in the cerebellum that deal with skill formation, billions in the cortex that perform the transformations for perception and rational planning, but only about eighty thousand spindle cells dealing with high-level emotions.

The dream acts as a safety-valve for the over-burdened brain. —Sigmund Freud
